Hey everyone,
. In a nutshell, my Mg. level constantly reverts to 1200 ppm from 1300-1350 only 1 week after supplementing with the DIY recipe of Randy Holmes Farley - which calls for a mixture of magnesium cholride and magnesium sulfate using Epsom Salts and BRS Magnesium Chloride.
Based on the infamous online calculator, with a net water volume of 65 gallons Im supposed to add 26.5 floz slowly over several hours and never enough to increase by 100pm per day. I test 24 hours later and my Red Sea Pro test kit shows 1350.
Either way, in a week it always falls back to 1200.
1. Is this normal? Ive always read that it takes a lot to bring up Mg. but once its up there it maintains fairly constant with water changes.
2. I surmised that it could be low Mg. levels from using Aquavitro Salinity which seems to always be lower in Mg. and Ca. than the stated ranges. So I skipped my 15% weekly WC and the levels still dropped to 1200.
3. Is it possible my corals are consuming this much? I only have mini colonies or frags so I doubt it, but stocking list is:
Frogspawn (6 heads)
Elegance Coral
blastos (20 heads)
Trumpet Coral (10 heads)
bubble coral
purple xenia
2x zoa rocks about the size of a tennis ball
Toadstool Mushroom size of softball
Devils Hand leather
digitata
maxima clam
