Your magnesium should be around 1350. Think of Mg as the fulcrum on a teeter totter. You can't keep alkalinity and calcium up if your magnesium is very low. In your case, it is very low. Try to aim for Calcium 400-430, Alk 8-10, Mg 1350-1400. pH should be 8.0-8.4, and Am, nitrite, nitrate, and phos all 0. Not close to zero, but AT zero.

no no i test for all those, just thought i'd point out the important ones first..

pH 8.3 ; ammonia undetectable ; nitrite 0.25 ; nitrate 0 ; alkalinity as mentioned 8 dKH ; phosphate 0

i'll start dosing some form of magnesium in that case, think kent tech-m will do it, i've been relying on my salt mix (seachem reef salt) as a constant source for magnesium!
