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

Overall, I've tried following the submission of many images and movies from the
Malawi to replicate the preferred of mine rock-Habitat.
Here I am essentially in the region around the Taiwan Reef in
15m depth maintained.
Here are mainly large boulders and stones on the ground
with few "sand cracks" in between!

Aquarium decoration:
************************************************** ****************************************

50kg beige quartz sand (0,1 - 0,5 mm) and 10kg light brown,
fine gravel (0.7 - 1.2 mm) and mixed to 15kg black / anthracite
colored quartz sand (0,5-1,0mm)

************************************************** ****************************************
No more!
In Taiwan Reef there is no ... :-)

Moreover, the gloomy lighting conditions and the hardness of the water in Berlin seem to prevent in my pelvis a vegetation.
All experiments with various plants and the various
Fertilizer additions have failed in the past (with the exception of Anubias species)!

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

Instead of Plants images I use the wildcards here for older Pictures of my pelvis as "development history" ... :-)

Special features of the facility:
************************************************** ****************************************
100kg collected, brushed and boiled river Break granite, arranged with many retreats / columns / Caves / and zones.

Instead of projecting 3D back wall - which always "fix" remains, I can simulate "natural" Rocky Landscape with stones / rocks one that at
Demand can be customized ... :-)

Everything built on 2cm styrofoam to protect the ground glass.

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

4x Jewel 3D walls (rear and side walls) Type "Gem Stone Lime", 60 * 55 to around
generate a sense of security / Security for the fish and for the protection of
Glass front of the stones which are built partly directly on the wall!

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

I have tried in my pelvis to create the right environment for my stocking:
For Copadichromis a kind of rock-transition zone with stones, rubble and a few sandy areas and lots of "free water".
For Sciaenochromis and Protomelas pronounced rock regions (with plenty of caves / niche!) And enough free swimming space.
All this I have tried as much as possible in my little "Taiwan Reef" as an underwater rocky landscape "biotopnah" implement!

The Taiwan Reef Region in Malawi

The size of Lake Malawi and its corresponding existing diversity of cichlids, make a not easy to decide on a specific region, from which the fish to be maintained originate.
For aquarium replica of a habitat near NonMbuna-habitat it is also irrelevant whether we are accustomed Wild from the region or bred.

I want to go step by step to such habitat.

The choice of the region has emerged for me it quickly:
Approximately 7km north before Chizumulu Iceland is the underwater lying "Taiwan Reef" with the most for me NonMbunas of Lake Malawi, the Protomelas steveni Taiwan Reef!

Accordingly, it was clear, a corresponding rocky habitat combined to create with free stretches of sand in my aquarium.
The next question which then arises is, what further types match the Protomelas and the habitat of the Taiwan Reefs?

After intensive research I have found that there are the following very beautiful NonMbunas from the preferred by my region, which can be associated together in an aquarium of my size and can live together in a kind of symbiosis:
Protomelas sp. steveni "Taiwan Reef"
Copadichromis sp. "Taiwan Yellow"
Copadichromis borleyi "Taiwan Reef"
Copadichromis virginalis "Taiwan Reef"
Sciaenochromis fryeri (seeweite dissemination)

The biggest problem is probably the procurement of Copadichromis be species from the region, because they are rarely caught and exported!

Aquarium equipment:
In this natural habitat, the spectral colors are "blue" and "green" still strongly reflected.
"Yellow" is just over 15 meters of water already in the absorption phase, already "orange" from 10 meters and "red" is already completely absorbed.
In this very special, plants loose biotope there are lunchtime a
lighter incident sunlight, otherwise prevails here almost exclusively the
typical dim-blue / green light before.

Depending on the connection of the individual tubes, I get in the pool more or less brightness / sunlight and more or less blue / green components.

So I'm trying rudimentary existing in the rocky habitat Lichtwechsel
replicate throughout the day without lighting computer. :-)

Classic "evening glow" does not exist, because it does not correspond to the actual conditions in the depth of the selected biotope me! :-)

(NB .: Many, many thanks to Silvan for competent information about the
Lichtverhältnissenin my biotope !!!)

The following bulbs, so I have tried to replicate this unique atmosphere in my "Reef":

T5 light bars (separately switchable)

- 1x OSRAM 827 "Relax" - Warm White, 28W T5
(ensures a slight incident sunlight at noon, when the
Sun is at its highest, almost completely wrapped in aluminum foil, with little
"Light gaps" and in the middle with a little yellow Decorhülse wrapped)

- 1x Marine-Glo 54W T5
(blue light, reversing the JBL reflector = indirect light from above)

1 x T8 GLO ballast

- 1x OSRAM 965 "BIOLUX" - Daylight, 36W T8 120cm
(brilliant light with very light blue shimmer in 1st row)
Partially wrapped in aluminum foil to obtain "shadow areas" and with green decor sleeves partially sheathed for a slight "green cast"!

1 x T8 GLO ballast

- 1x JBL Blue Moon, 40W T8 120cm (blue light in the center area)
Partially wrapped in aluminum foil to obtain "shadow areas".
This tube I reach the typical "blue glow", which prevails in large parts of Lake Malawi at depths of approximately 15-20m.

************************************************** ********************************
Moonlight beams with 12 LEDs, light color blue, dimmable, and 2x 5-LED

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

Lighting times

8:00 a.m. to 10:00 Moonlight 120 min (end of night)
10:00 to 22:00 Blue Moon Marine tube and GLO for stronger blue components
11:00 to 21:00 daylight tube "Daylight" for daylight with light blue / green Shares
12:00 to 15:00 "Warm White" tube to a slight "solar fraction"
22:00 to 1:00 Moonlight 120 min (start of night)
1:00 to 8:00 Darkness

Reinebeck lighting with "daylight" So 12 hours.
Everything in each "smooth transition".

Seems to me to be an acceptable solution, as long as I did not make
"Professional Lighting Computer" have, which can simulate anything ... :-)

The following stocking we currently maintained in my pelvis:

M / W

3/7 Protomelas sp. "Steveni Taiwan" (NZ)

1/3 of Sciaenocromis fryeri (NZ)

1/3 of Copadichromis borleyi Kadango "Red Fin" (NZ)

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

So there are 18 NonMbunas in the basin.
Full grown were the approximately 187 cm fish ...
That is about 2.9L of water / cm fish or 30l / fish (gross) or approx 22l net / fish.
Think this is a well fitting frame.

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

The fryeri and Copadichromis Bock held in Harem attitude with 3 females!
The Protomelas in group housing :-)

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

My goal is to trim principle "biotopnah" select.
This has now happened, "Step by Step"!

The Copadichromis borleyi Kadango be yet another Copadichromis-pack from the Taiwan Reef soft, depending on the commercial availability!

************************************************** *************************************
Of course, no hybrids are passed from my pool!

Stocking rate in the aquarium

The following is recommended in Sachkundenachweis (SKN):

Fish length amount of water per 1 cm fish length

under 2 cm -> 1 liter per cm fish length
2 cm - 5 cm -> 1.5 liters per cm fish length

Water parameters:
Good, hard Berliner tap water: :-)

Temperature: 26-27 ° C
pH: 8.0
GH: 12
KH: 8
NO2: <0.3 mg / l
NO3: <12.5 mg / l
NH3: undetectable
NH4: undetectable

-> Regularly determined by Tetra droplet test.

Water exchange

- 50% a week + in midweek (Wed) approximately 40L "fresh water syringe"
- 5-10l daily for balcony flowers (spring - autumn)

-> At every water change is treated with JBL AquaDur (Malawi / Tanganyika) by 1/2 Dosage water especially for east African Cichlids (containing no NaCl = common salt!).

The water quality of the East African Lakes Malawi and Tanganyika grave differs significantly from Central European tap waters. Characteristic are carbonate hardness, higher than the values ​​of total hardness and more or less strongly alkaline pH values ​​around 8-9.
JBL AquaDur Malawi / Tanganyika makes both tap water and osmosis water from the water towards the welfare of East African cichlids.
Here, the pH is adjusted and buffered to the required alkaline range.
This acts conducive to blaze of color, spawning and health.
By using this special salt the special characteristics of Malawi and Tanganyika lakes can be reached.
The carbonate hardness is raised above the total hardness and the typical for the lakes mineral compounds supplied to the aquarium water!

However, this works so not quite in my pool because the GH that is quite high with approximately 13 °, and the KH-value at me can not be brought about or more than 8 also would be too high, but so with me on definitely be the important mineral compounds * * added!
So far I have observed that this had a very positive influence on my AQ-residents ... :-)

The carbonate hardness is basically one of the most important water parameters aquatics. The KH stabilizes the pH, thus preventing the dreaded drop in pH as a sudden sharp rise in pH, which is just as dangerous.
The KH should never drop below 4 ° dKH in normal community aquariums!
Even if the raw water had once exhibited sufficient KH values ​​KH may decrease in the aquarium! This can be done through strong bacterial reduction activity or CO2 deficiency, then get out at the plants and algae are the necessary CO2 from the KH.
As a result, KH and the pH drops is unstable.

-> Every 2 weeks I admit after the water change Easy Life (after dosing indication) for the preventive water treatment in the basin.

ATTENTION: (22:09:10)

Immediately I omit the addition of salt jodfreiem after water changes because I use zeolite in my filters!
This has the (valuable) object to bind pollutants and to support the biological filtration.
This also applies to the use of water conditioners as EasyLife or Lewatit (ion exchange)!
So far so good!
A really positive meant the addition of salt, however, means that the zeolite (and Lewatit) bound toxins can be released suddenly and be issued on a time to the water again, with possible catastrophic consequences for the fish! So diseases can certainly be worse!

Appears also logical because zeolite (and Lewatit) is yes, finally regenerated with saline again ...!

It makes more sense (anyway), to isolate sick patients in a quarantine tank and then specifically there - perhaps even with salt - treat!
