alllmost ready to begin filling up the new 90. a very exciting time.
im running 2 sumps because of the way my stand was designed and i finally discovered a method of running side by side tanks that should be flawless.
however, after reading around, im hearing more and more bad thing about bio balls. I know that they are good for taking care of NO2
levels, but im also aware of the harm it can do to the NO3
levels. do the cons outweigh the pros? what's your take on this hole bio ball bonanza?
Just a note: it will be a FOWLR
for the first couple but i'll start gradually adding coral as it reaches the end of its cycle and is fully stable.
i have enough room for the balls, and building a conpartment for them in one of my sumps is what i planned for but im having second thoughts.
