Garf , thanks for response . My attempt to eliminate alien growth via adding iron wasnt succesful at all. Growth did not changed , but instead I got algae in display, that I never had before. I was trying to use difuser to spread LED light somehow. That made no effect as well. May be reducing hours will help. I reprogramed my controller already . Will see next week if growth becomes more usual .
Regarding micro fauna that is very good guess . I completely agree with you.
I do all my best to maintain stable Ca and Alk. But having that many animals in small tank is very hard. They consume Ca and Alk at such amounts , that it is difficult to adjust doses to their needs. I bought dosing pump for that reson. I hope I will have final settings for it and will get more stable params.
What would you recommend to reestablish micro fauna population ?
