Kh 9.3
Po4 .25
I’m experiencing somethings not right , Xenia is closed up, zoas half open , mushrooms half retracted
There was a load of black bits in my ato , I presume carbon particles , also a couple of rock hard lumps black 1” so I’ve emptied and cleaned the ato
I put carbon online yesterday hoping it would improve things but still the same
Any ideas guys?
I might add that while I was away 5 days my light fell in the water and blew , also my po4 and no3 bottomed out to 0
Nitrates now 1
