Re: Aquatic Plants Digest V3 #1126
If you don't mind a bit of magnesium with your calcium (actually plants
*need* magnesium) "garden lime" used on lawns is a good source. At
~$3.00 per 40-lbs bag it can not be beat. What if some of it doesn't
dissolve readily? Lot of it does, the rest you just throw out.
