Magnesium Dosing

[mark]

Still think it's something to bring the levels up for my water changes I need to add nearly a cup of bulk Mg and I'm only changing out 20g at a time.

Well I picked up some Magnesium Sulphate Heptahydrate U.S.P from my Save on Foods. I needed grocery's so I thought I would check on the price and it is cheaper ($5 for 2kg). Yeah with magnesium chloride I am dosing the same ingredients as the Kent Marine product so I will get some of that aswell.

According to the Reef Chemistry Calculator I need about 500 grams... I don't have a scale... Approx how much will give me a 100 ppm increase?

All of my live stock is in my signiture. For lighting I am running 4 T5HO 24" Bulbs (1 Atinic, 1 Coral Growth(pink), 2 10 000K). I have 3 power heads (1 Koralia 2, 1 Koralia 750, 1 Koalia nano with the 2 and nano on all the time) Red Sea Prism skimmer and a fluval 405 canister (yes I clean weekly).

I have about 55lbs of live rock rangeing from 10 years old to new stuff and about 30lbs of live araganite sand.

I really should put my tank in the tank journal, but its not done yet (my wife saies it never will be... I tend to agree)
