I cant keep alkalinity up...

[tvasi]

I have a 5 gal nano, and it seems to suck up the alkalinity and calcium on a daily basis.

I dose with C-Balance, and drip kalk (top off only), I do 20% water changes once every 2-3 weeks.

I seem to drop 1.5-2 dKh and about 60-70 ppm of calcium every day.. And thats with dosing the recommended dosage of C-Balance.

I do have quite a bit of algae in it, halimeda growing all over the place.

Could the tank possibly be using that much?

thanx

what kind of salt are you using?

if it is low in magnesium it could be part of the problem.
