Calcium & Alk. Additives - What's best?

[reeferious]

had been considering getting calcium reactor package until i came into possession of some bulk ca and alk supplies. now i spend 30 seconds every other nite double dosing recommended amt into my sump. 2 months went by and all my critters are doing fantastically well. haha why babysit them when we all know those creatures are a lot tougher than you and i. relax, sit back and stop all those worryings.
