I'm a big fan of kalk. I have tried the drip method and the 24/7 dosing method. Both work well. My next thing might be to try a
kalk reactor.
Whatever you do though, I'd start off just using 1 tsp/gallon until you're more experienced with it and then move up to 2 tsp/gallon. Reason is that if you don't have a system of delivering and a disaster prevention plan ( ie dose too much ), you could kill everything by dosing too much
When you're tank demands a little more than kalk can deliver, you can get frisky and start using vinegar with it.

I don't recommend that for the beginner though because it makes the kalk very potent and you hsould need to have your system of delivering down
