LOL @ Lanzo - try "Bryopsis" nuisance algae ;)

No probs with your readings, at this stage Mike..... Just don't dose anything that has Mg in it..... Just keep on measuring, and see the rate of usage....

Mike you can adjust your alk with Baking soda (not baking Powder) it must be mixed up in some R/o water and dripped into the tank slowly and do not lift it more than 2dkh a day

here is a link to a calculator to work out how much you need

You are going have a coralline problem soon, it loves Mg.

What salt are you using ? check it's Alk rating and it may show you the source of the low levels.

Then there is the prob, seems (from my tests) quite a low ALk salt, almost as low as TM.

Does he have any creatures that could be consuming the ALk - Clams, SPS, Coralline ?

Test your salt dude.

If you going dose Baking Soda, then make sure you match your tank's alk when doing WC, or you going be fighting a losing battle ;)
