I've got Plenty of BGA despite a 4 day "blackout". Nitrates/nitrites are zero accoring to testing.

I have noted a few cherries die in last week but none of my water values have changed nor have I added/taken away anything (except 20% water change w/ R/O as usual).

I'm just wondering if the BGA is affecting my cherries (diet?). I do feed every other day w/ spirulina flakes to supplement their diet.

Any suggestions?

BTW - the amanos end up eating the fallen and all I see are the remains, canibals!!!

Cyanobacteria in general are an indicator for bad water quality. Shrimp may eat certain cynabacteria, but don't eat most "nasty" slimy varieties ocurring in our tanks. Plus, the cyanos might be releasing toxins into the water in addition to being indicators for bad water quality. All in all, I would recommend that you stop feeding, remove all the cyanobacteria by hand until it stops coming back. Perform 50% water changes every day for the next 3-4 days and 50% at least every week thereafter.
