replenishing magnesium
 

Just curious to what product everyone is using to replenish magnesium in their reefs? Powder or liguid and why? thx.

I use Kent's Tech-M Magnesium and buy at least two of the big jugs from J&L when ordering dry goods so I don't run out. I drip kalk in all three of our reefs, which helps sustain Ca and alk levels, but does nothing for Mg levels. Sure use a lot of the stuff :eek: Anyway, it's a liquid and easy to measure with a 10 ml plastic syringe from the drug store. Make sure to shake liquid Mg thoroughly while using as the heavier particles settle out quickly.

I have the crystal form that I add to top up water when levels drop. They take a long time to disolve which sucks but they are cheeper. I think mine are Sea Chem.

Does everyone supplement magnesium or just some?

Everyone should make sure their mag. levels are good. I'm sure Bev can supply the links as to why. :biggrin: Get your reading glasses ready!

Hope you have a few hours to kill... :mrgreen:
Good stuff though!
