55 gallon tank, 2-3 months old, regular testing, water changes, etc.
Been having a problem with either diatoms or cyano (I think) so I took out some of my rocks yesterday and brushed them off with a toothbrush. The ones that weren't easily removed I brushed in the tank. Did a 30% water change, matched temp and salinity did not move more than 0.001. used RODI water with TDS of 3. Rinsed out the mechanical filter too.
One of my clownfish showed signs of distress, I thought it might be oxygen related so I added a bubble stone for the night. Kept the power head and Fluval G3 filter running as normal. This morning both of my clowns and my cardinalfish are dead.
Tested with API test kit this morning:
Ammonia: 0
Nitrite: 0
Nitrate: 0
SG: 1.026
pH: 8.0
Calcium: 460
KH: 8
Exact same readings I had before the change. Any idea what could have happened? Photos attached of what I was trying to scrub off
