Nano tank chemistry issue

[calebsmith7]

I have had a five gallon tank for about two months, I have corals and two clowns, but all of a sudden, the corals started closing up. I tested the salinity and nitrates, (which have caused me problems before) but they’re still perfect. I don’t know what the problem is

What are your phosphates and other parameters at?

They’re all good, but I think the test strips I’m using are not very reliable

Yeah strips aren’t worth having, get hanna checkers or redsea or salifert kits
