It's been over 6 weeks since setting up my tank and everything has gone okay...except now my snails are turning up dead at the bottom of my tank...to date I have about 5 snails ( 2 Mexican and 3 Turbo) DOA. All the water parameter are good...My Nitrate level is some one elevated but, with water changed about 10% every other weekend they( Nitrate) have gone down, but never too 0, I always have a trace of nitrate....Should I remove all my bioballs from my sump tank???....I have a 90 gal
tank with about 80 lbs of LR
. I hope the cycle is coming to an end...I've notice a brown type algae on my glass. The nitrate and the PH
have been the only noticeable changes since the set up... Any ideas what could be the killer in my tank?
All I have are 5 small blue starter fishes and 2 damsels and about 20-25 clean-up crew, plus 1 Coral Banded Shrimp and 1 Cleaner Shrimp and 2 gobies.
