Kalkwasser...GOOD or BAD

[downhillbiker]

I was just wondering if this product was good or bad. I was told my a local reefer that I should try it. I was told that it raises PH but then levels out, and can work great. I like that it is all in one, and i dont have to try and balance calcium and carbonate alkalinity to the tank. I know it may not be as accurate, but I like less headache.

What do you guys think about this stuff. My friend has food grade Kalkwasser that he is selling cheap. Should I do it?

Otherwise known in English as limewater, it is used by probably a quarter to a third or so of experienced folks on this site. It is a fine and inexpensive (if you buy inexpensive brands) way to supplement calcium and alkalinity, and to help keep up pH if your home has excess CO2 in the air.

It must be dissolved in fresh water and added very slowly, as in dripping or slow pump.

It's what I've used in my tank for calcium and alkalinity for more than a decade.

i like kalk.. i started using it after i set up a cal. reactor..not hard to use.. can drip it or put it in your ato.

great for maintaining levels. I use a two-part to "bump" levels up occasionally, as needed. It's cheaper if you buy pickling lime rather than the stuff labeled for the hobby. Ball's or Mrs. Wage's are good and lots less $$. Be sure to read the links from Randy.

^^Agreed.

I live by it. No reason not to use such an inexpensive Ca, and alk supplement.

Does anyone know if hydrated lime from the local garden center is the same thing ???

If you're looking to go with a non aquarium brand, best bet is food grade pickling lime. Mrs Wages is a popular brand. Very cheap.

I would worry that the agricultural grade stuff may have impurities.
