Description of the aquarium:
Category:
Lake Malawi
Tank size:
150x50x52 = 375 liters ~ 99 gallons (us)
Specific features:
After my first year running a pool on now already and so far everything has been very good work it's time to take this summer a new project in attack.
With my first bowl I had also South America focused me, but this time I wanted to leave this continent.
After my enthusiasm for the Asian region held rather limited wandered the focus on East Africa and the local grave lakes.
Although the Lake Tanganyika has its charm liked the Malawi slightly better, especially since I will also direct a species found that convinced me immediately.

*****************************************
It should therefore be a Malawi basin.
Outfitted as a species pool for Ps. Demasoni.

*****************************************

Looking for a suitable pool I found in a tender a used 375l tank (150x50x50cm) with velvet black cabinet and cover (which wanted to be but fashioned only times of gray to black)

Because the pool is on an outside wall near the window and the morning incident sunlight would fall directly on the left side window, this had to be darkened.
The same was true for the back side, otherwise the white wallpaper would be visible, which would harm the general rather dark look.
So both discs were darkened with static liable AutoglassFilm.
The feared reflection failed to materialize and the whole works great.
To visually enhance the edges and covering the ends of films black-painted corner strips were glued.
The spray-textured paint used in this case and for the cover is worth gold.

Aquarium decoration:
Gravel:
When pools several bags of mysterious "black" gravel were about the at first glance not bad looked and could go well.
But upon closer inspection on a lot at once, in addition to the beautiful black grains small splinters were present everywhere.
This worked extremely sharp and "glass-like", almost like little pieces of broken glass.
According to research and some reports I learned that such a black gloss gravels are preferred to win time of blast furnace slag.
And something in a Malawi basin, where the fish might like to browse the ground? - no way.

*****************************************

Although a dark ground to bring the colors of the fish better advantage fell my choice on a lighter quartz sand from the local Building Materials.

So: ca. 40 kg lighter beige quartz sand with a grain size of 0.3-0.5 mm

Despite the award: washed, dried and dusted fire I have the sand a few times washed, what indeed turned out to be potentially unnecessary expense, but clarify the water accelerated.

Thus, the sand without air inclusions could be introduced it was poured into the already partially filled aquarium.

*****************************************
Plants:
Although plants are not typical of the natural habitat of Ps. Demasoni I do not want to give up some green aspects.
First, they act as a contrast to the dark stone constructions and the bright ground.
Second, they work very well as a retreat for young and small fish.

Of course, planting on bass just plants limited:

Anubias barteri - Speer leaves
in the variants: barteri, nana nana & 'petite'

The Anubien're seemingly in the classic perch or Malawi basin.
And also for me they are "grown" to one of my favorite plants.
So they may not be missing here.
In an online shop of my confidence, I found directly Anubias package.
Including:
- A mother plant Anubias barteri (with handsome height and width of about 25cm)
- Two pots A. barteri
- Three pots A. nana
- Two pots bonsai A. n.


Since the individual plantlets were very large part they were divided partly.
As with Aufsitzer- or rhizomatous usual, I've strapped on the stones.
Especially the combination of different sizes is visually amazing.

Light requirements: very low - medium
Temperature: 20 - 30 ° C
pH: 5.5 to 9.0
Water hardness: very soft - very hard

-------------------------

Vallisneria spiralis - ordinary water screw

Since these plants send almost to proliferate now my entire basin and South America to be sorted out on a regular basis, it was almost obvious that one or the other branch would probably migrate to the new pool.
Here they form the "picture frame and cover on both sides, the edges of the rear wall.
Since they are apparently rather undemanding I just have to make sure that they do not like to start at the other pool with the time to proliferate.

Height: up to 2 m possible
Light requirements: medium - high
Temperature: 18 - 28 ° C
pH: 6.5 to 8.0
Water hardness: soft - hard

Special features of the facility:
After some back and forth I decided to set up a home-built rear wall instead of using a purchased.
After studying various building instructions the plans were laid.
Two rear panels in the two corners of it should be, which cover the side windows and on each one-third the rear window.
A third element, which should cover the middle, while the construction of the two corner elements discarded
In the right rear corner of both the intake and the heater is hidden.

The base of the rear wall form 10 cm thick styrofoam plates that have been processed using a heat gun.
In order to enhance the spatial effect the Styroprdicke was doubled in some places.
In turn, (and because when blow drying partly holes were burned into the wall) have been incorporated on the back of the wall transitions that will allow the fish to swim along behind the rear wall.
After a multi-layer tile adhesive paint (colored with Tinting in black and white) followed by the sealing with epoxy resin.

I think the results can be quite impressive, but after several hours of work were invested in the construction.
Should I once again come into the embarrassment to build a back wall I now know what to look for and will definitely have much less trouble with it.
I sincerely hope that I have done correctly when building anything and everything turned out as it should.
Again and again, there is talk of incomplete curing and late side effects by substances that have been separated from the wall at the backround.
Since I had been looking extensively at the materials and have resorted to recommended sources I hope, however, that such horror stories are not happen with me.

Were glued the rear wall parts with black aquarium silicone.
Here, I've probably used as much, that an expansion might be difficult.

*****************************************

In addition to the caves which provides the rear wall need the Ps. Demasoni representing the Mbuna more rock structures.

For this form 12 basalt paving stones the foundations for the rocks.
These were piled up from just under 80 kg Warsteiner fracture to three groups of rocks.

The foundation of the stone constructions rests directly on a 3 mm thick plexiglass screen is indeed offer little protection against rockfall, but sufficient, the bottom disk from scratches while you set up to protect.
Since the stones were but built directly on the floor and not on the sand, the fish do not undermine the stones and then a collapse of the superstructure only be triggered by careless handling.

The stone structures are broken down into the main rock in the basin center and two small rocks on the sides. The main rock covers about half the pool length between the two rear wall parts, so that the remaining open space is covered.
Almost up to the windscreen and partly piled up to the water surface of the main rock forms a partition between the two pelvic halves.
Since the stone tower height increases steadily tapering forms the Bursting Stone series only a wreath and rear window creates a large-scale craters in addition to the mother plant Anubias and a second flow pump could provide a hidden place.

On the right side, a smaller rock structure forms a tunnel to the suction point in the pelvic area.
This page also found an artificial rock of the basin was there and optically to the stone towers fit into place.

*****************************************

Overall, the rock structures and the durchschwimmbaren rear wall elements form countless caves that are the Ps. Demasoni as retreats available.
This makes it difficult, although in the long run determine the exact number of fish, but increases the tension when observing.
It is virtually never possible to see all the fish simultaneously.
It is also very captivating to watch the fish while swimming through the rocks, or watch as they curious look out from the crevices.

After the bright ground the colors of the fish only [...]
Aquarium equipment:
Lighting:
The basin and the cover has a total of four T8 tubes, which were also fully equipped with the takeover.
As for Malawi basin not too strong lighting is adequate and well-kept plants will manage with less light is turned on only one of the existing pipes.

Even the light of a T8 tube is almost too bright, it may be necessary here to be improved and a blackout be made.

Is Illuminated 8:00 to 12:00 and 4:00 p.m. to 22:00.

The current burning Neonsonne is a 40W Aqua Glo.
The light color looks pure optically somewhat purple, what strikes me as something unnatural.
Since I am not entirely satisfied with the color of light I have to look mal ne alternative to me here. Possibly also a switch to LED conceivable.

*****************************************
Filtration:
The filtering is performed by a external filter:

Manufacturer: Eheim
Type: Professional 3-600; 2075
Pump capacity: 1250 l / h
Power Consumption: 16 W
Filter volume: 6 l

As filter media, I leave the MECHpro supplied the filters in the two lowest filter baskets. Instead of bioMECH and SUBSTRATpro, which was also the filter case, I have filled the upper two baskets with Sinterglaßringen in two different sizes.

Installation sets 1 and 2 of Eheim come As with the South Basin here again for use. The intake is tucked behind the back wall, so it is not visible.

*****************************************
Other equipment:
Heater:

EHEIM Jäger Thermocontrol 150 suitable for tanks of about 200 with a power consumption of 150 W - 300 liters of water volume.
Here you might think that the performance is marginal, but so far it seems to be sufficient. The temperature must of course be closely watched when winter approaches. The heating element is hidden next to the intake manifold behind the rear wall.

*****************************************

Stömungspumpen:

Two Turbelle Nano Stream contribute to the flow generation.

Pump No. 1 behind the central rock.:

Manufacturer: Tunze
Type: Turbelle nanstream 6015
Flow performance: ca. 1.800l / h
Power Consumption: 3.5W

The small flow pump which was installed at the beginning at the left side window has been postponed in the wake of the advent of larger flow pump behind the central rock, so that they now displaced from there the right pelvis mainly near the surface in the flow.

Pump No. 2 on the left side window

Manufacturer: Tunze
Type: Turbelle nanstream 6045
Flow capacity: 1,500 to 4,500 l / h
Energy Consumption: 5 - 7W

The flow pump is hidden on the left side behind another self-constructed rear wall element, so it is not visible at first glance.
The flow is directed to the left front corner of the rock, so that the left half of the pelvis literally "blown free" is, and the sludge is transported in the direction of intake. The pump is currently running unthrottled at full power.

For a second flow pump a crater is prepared behind the main rock.
Depending on requirements, there are hidden another Turbelle.
Stocking:
- Pseudotropheus demasoni -
23-28 animals of various sizes / generations
(Sex ratio unknown)

Ps. Demasoni is a beautiful attractive Mbuna which can reach a maximum size of 6-8 cm. Unlike other Pseudothropheus evident when demasoni no sexual dimorphism, which significantly complicates the distinction between the sexes. Already the fry show the typical showy light blue-blue-black stripe pattern of the parents. The entire brood care assume the females. While the pups are able to find in loose groups show adult animals intraspecific a very high potential for aggression. In particular, the males can be very aggressive when it comes to defending the food coalfield. Since every individual occupies a large food area in natural habitat lies in the aquarium always a certain lack of space.
To have the intraspecific aggression compensate sufficiently retreats are offered in the form of large rock structures with many caves for inferior animals. It is also recommended to maintain a healthy overstocking, as this can spread the aggression.

*****************************************

Ps. Demasoni is cultivated here in a species tank.
About a socialization with L. caeruleus I had originally thought, but I had so far decided against it.

Water parameters:
The water values ​​are determined using a JBL Drop Test:

(last measurement 24/09/2013 21:00)

Temperature: 25 - 26 ° C
Ph: 7.6
GH: 17 ° dH
KH: 13 ° dH
NO²: 0.05 mg / l >> partial water change is carried out
NO³: 20 mg / l
PO³: 0.05 mg / l
Fe: <0.02 mg / l

*****************************************

Of the local Stadtwerke a drinking water analysis is provided for the service area, which returns the following values ​​for the output water:

Ph: 7.5
GH: 17.0 ° dH
KH: 11.7 ° dH
NO²: <0.01 mg / l
NO³: 25.9 mg / l
PO³: Info
Fe: 0.075 mg / l

I try the water changes very latest ensure every 2 weeks for 40% each.
Feeding:
Since Ps. Demasoni are absolute nutrition specialists that it is to eat in their natural habitat only by cultivating the food to look more closely.
Due to the specialization of their digestive tract they may include animal protein-heavy foods (for example, mosquito larvae) difficulties recycle and suffer this can cause serious illnesses. Instead, attention must be paid to high-fiber feed with a higher vegetable content.


Mostly they get with me granulated food:

Tropical: SUPER SPIRULINA FORTE GRANULAT
with a 36% share of Spirulina platensis


Occasionally a "Veggie Day" is inserted:

Tropical: Cichlid Herbivore pellet "S"


Alternatively, there's occasionally flake food:

JBL: Premium - Spirulina
with a 40% share of Spirulina platensis


rare sticks are given:

JBL: NovoRift

*****************************************

Fresh food such as salad of cucumber I have not tried yet, but eventually comes the time even on the menu.

On one or two days per week a fast day is inserted.

At present there are still not too many photos online,
this will change in the near future step by step.

About comments, suggestions and comments I would be glad of course at any time.
