I checked my water yesterday and my nitrates and nitrites are almost zero. My ammonia on the scale i forgot the exact reading but it said i was in the safe zone.
Declining water parameters are a sign of over-stocking. What does "almost" zero mean? NO2
NEED to be at zero, any minute detectable amount is unacceptable. NO3
should be less then 10ppm. IMO
, you are over-stocked and may have some poor compatibility. the tangs and the angels alone need a MUCH larger tank to house this many. As time goes by I am sure aggression will be an issue. You also have some pretty messy eaters there which could contribute to the poor water parameters. Consider thinning out your stock by at least one tang and one angel. What are you using for filtration and are you skimming?
