Given the failed attempts to play and as I learned from my mistakes, I tried to make changes to my cube in order to minimize "accidents" that could affect the outcome of the next replay.
I removed the internal filter and left only the external filter in order to completely eliminate the problem of "killer jets" that I have sucked the first time the small screens and that if they raise issues of water flow into the filter setesso.
I made a screen that collects all the suction tubes and which distributes the flow while the filter without risk to the children ...
I decided to remove the heater also seen that some died larvette just because you place on it, in its place I put a Hydor external heater which to date has proved much more efficient than with a constant internal temperature even when the temperature has dropped ...
I have implemented a system of automatic drip by placing a collection tank where I post osmosis water + salts on a cabinet next to the bathtub faucet with a cannula connected allows me to control its flow. I then added the overflow of my craft project (see other topic) to drain the water.
That way I can guarantee a good water quality during the reproductive period without disturbing the fish and without creating hazardous changes in values.
I adopted as a lighting system with dimmable LED strip to, this allows me to create soft light situations very popular with discus and allowing light to leave a minimum 24-24h
Finally I modified the flow in the tank to reduce the turbulence generated by building a small-scale Spray Bar with a PVC pipe with holes.
The couple has already been transferred in the cube, now look forward to a successful hatching of the next ...
