Anyone know anything about this? my wife found this online last night and supposedly it can be a substitute for kalk? maintaining your calcium and alkalinity? It's a food grade calcium carbonate from my understanding and sells for 2$ a pound or something crazy like that? Either way I just think it has to be to good to be true. I would think if it was something that was safe and effective everyone would be using it by now? just thought i'd get some info on it if anyone has any?

All Kalk powder is is Calcium Hydroxide (no Calcium Carbonate). You should be safe using it if it is food grade. Most of the chemicals we use can be found cheap if you want to buy in bulk AND you can assure the purity of the chemical in question. You generally want food- or lab-grade versions to assure that the chemical has minimal impurities. I've seen people use deicer (calcium carbonate) as a calcium source...this scares the bejesus out of me as there is zero assurance about the purity. I mean, who cares if there's other junk in there if you're just throwing it on your driveway, right? Personally I don't have the time to deal with this so I buy in bulk from Bulk Reef Supply. This way I get good quality, don't have to screw around with sourcing myself, and I get a pretty good price. BTW - If you're looking for Kalkwasser powder cheap, I've got some I'm selling... go here. |
