low calcium and alk,please help

[wrenchhead]

I just checked my tank's water tonight and I can't seem to get my calcium and alk levels up.calcium=340 alk=6.3 What do you guys try to keep your levels at and how do you get them there ?

Oh yea,I dose the tank almost daily with oceans blend 2 part ALK and CAL

If you are constantly adding those 2 and can't raise anything, it is probably due to low mag or not adding enough. Have you tried switching brands or to a homemade 2-part?

i try to keep my levels at 400-420ppm/Calc and 9-10 dKH/Alk. what salt brand are you using? how much 2 part are you dosing? how often do you do water changes?

I agree with dc...classic results when Mg is too low. Check your Mg levels before you add any more 2 part.
