I've had my 75 gallon reef up for about 6-7 months. Everything is doing great until I checked my parameters this morning. My ph is at 8 and my carbonate hardness is at 5 dh.. i thought it was supposed to be at like 11-12. I have a small yellow tang 5 green cromis and a sleeper goby. Everything is doing great and the coraline is taking over the walls. Also, I found these parameters weird cause I have started to dose kalk about a week ago, bout 1 drop every sec or two. I'm using the tetratest test kit.How do I get my parameters back in check?
TIA
