You have a really nice tank. I think I missed something. I see that you are running an algae reactor and biopellets. I'm wondering where do all the nutrients come from? You don't have a big bioload. I love your lighting. I was thinking about going T5, but the cost added up really fast over my tank.
So basically the seachem basic marine ph and alk test sucks. Lol.
It measures and shows results in measurements of 0.5meq/l and basically tells you if your ph and or alk is good or not. Lol.
Gonna order a salifert alk and cal test.
I chopped up a branching montipora last night in hopes of the rtn or stn stopping. It had what looked like bj on the base where thr die off started. Sux.
I dont think any of the frags i cut are gonna make it either.
2 other montis alson arent looking well. Undata and rainbow or skittles as they call it now.
