Raising Cichlid fry in hi-tech tank?
To get my keyholes to breed and parent, I had to use CO2 to fix the pH at slightly acidic.
The fry are into their second week and are eating/growing amazingly. Parents are doing a great job too in this heavily planted, dirted tank. All the little souls are still accounted for.
I test Nitrates frequently and the plants are using more than can be generated by waste. I have to still add EI ferts in small doses to keep the plants happy.
So here is the question: Is it alright to raise the fry in this setup without frequent water changes?
The reason to change water is to prevent build up of Nitrates, but the plants are consuming all the nitrates at a rapid pace.
If I do a large 50% WC, that will introduce a large swing in pH, so instead i've reduced EI and doing smaller WCs.
