Things have changed in this hobby since the last time I studied saltwater tanks, and a few things are not clear.
What is an acceptable level of nitrates in a FOWLR
tank? What is achievable?
Is it essential to have 4" of sand? Will 1-2" function as a filter bed? Can you add new sand on top without screwing up the sand bed already in the tank?
How much does PH
vary? What time of day should it be checked, and what should it be?
I have taken my bio-wheels off. That is the correct thing to do, yes? (It now provides a lot more water movement in the tank.)
I just bought another 55 gal
tank. Should I link the two 55s together? How is that done?
I want a yellow striped maroon clown next. Should I get two or will one be OK by itself?
Thanks very much for your help!
