While at the LFS
yesterday, I made mention that I'm still having problems getting calcium up to 400ppm (seems i'm stuck at 350) and alkalinity up to 3meq/l (stuck at 2.5). My pH is usually 8.1, and my Mg
levels have stayed at 1200-1250mg/l.
I only have mushrooms, yellow colony polyps and just added some button polyps this weekend. Lots of coraline though.
Anyhow, the guy at the LFS
mentioned supplementing with strontium...that maybe my coraline is using more calcium than it should because my strontium levels are low. I don't have a strontium test kit, but I'm wondering what you all think?
He also mentioned iodine to brighten up the corals. That's definitely something I won't dose without testing
