The basin is bulge-glued and has 2x40er processes.
About the processes I'm doing the weekly water change, in which I was there the "plugs" draw. Then rushing 300 liters within 1 minute of it. This water is not wasted in the drain but is fed directly into our cistern for watering the garden. So I have always some water, even if the baby might not rain during the summer.
Is replenished by the pool fresh water supply, which comes next to the pool out of the wall. In other words, I just turn on the tap and wait until the tank is full - in sum I need as for the weekly water change about 15 minutes.
The basin is in our new building, so we had the opportunities, rather easy to implement the supply and sewers. So we leave the concrete floor where the pool is, verstäken. 1500 kg per square meter are no longer a problem and leaves space for other mills at a later date ...
Under the pool is a welded base in 40x40 square tube in 3 mm thickness. The structure is as follows: + recessed concrete floor separately for the pool size of the screed, it Styrodur in 2 cm, then a 18mm multiplex plate. Then the steel frame, then 2 x 18mm multiplex and 2 cm Styrodur. This is then a 5mm Aquarium Pad and finally the pelvis.
Mixed quartz sand, 125 kg.
Special features of the facility:
In the basin 400 kg basalt boulders were installed. It was important, as close as possible available to get at the actual material in Malawi. And with the growth that has now set on the stones, it actually looks to Malawi from ... Among the stones is Styrodur, among smaller stones just Plexiglas.
When backplane I only mounted a black film outside. This absorboert the light well, so that the animals like to be able to withdraw also times in the shady areas of the basin.
LED. In sum not too intrusive in my opinion, these two colors a beautiful light, the algae grow wonderful and the fish show their beautiful colors.
Beleuchtzungszeitraum: 16:30 to 23:30
1 x Fluval FX5 with> 3000 liters / h 2 x jewel Bioflow with 1,000 liters / h - is working fine, the suspended particles filtered out of the water at very low power consumption. One sees the two Bioflow front also not because they simply are like the back wall black.
3 x flow pumps, each with 8,000 l / h. Are alternately controlled by timers to produce different tendencies. No more heating available - the pool has 23 degree and at least in the summer max.. 28 degrees.
8x Pseudotropheus elongantus Neon Spot, 3/5 6x Labidochromis Mbamba, 2/4 + approx 5 juveniles in the pool <3 cm 6x Labidochromis Hongi "Red Top", 2/4 + 5-10 Junfische in pool <3 cm 9 x Labidochromis Caeruleus, probably 3/7, they are at the 3-5 cm 4 x Melanochromis Maingano, 1/3
8x Synodontis Mulipunctatus, probably 3/5.
Also located in the pool 1/2 Sciaenochromis fryeri and Dimidiochromis compressiceps 1/2 who like decimate the offspring of Mbunas something.
Water hardness ie: 13 pH: 7.6 Water temperature: 25 degrees
Water 2 times 150 liters per week. This corresponds to about 30% of the actual net volume (sand and stones are deducted, gross pelvis has indeed 1,400 liters) per week.
The Mbunas almost graze all day on the covered rocks. I am of course pleased that they present this natural behavior to the day in our pool.
2x per week: no feeding, fasting Otherwise 1x per day Füterung. Here, a chuck is always used, which is a mixture of: 1. granulated food 2. Sticks 3. flake food from algae for Mbunas
In addition, the fish get 1 x per week a Virtel a cucumber, which they love to eat.
