Kalk

[Tim Marvin]

Interesting..... I had a .6 change in PH, but I probably added a higher percentage per water volume.

Yeah I drip kalk every once in a while. it usually only lasts about a week though and i get tired of mixing it and messing with it. I am going to get a kalk reactor from Jim D as soon as I get paid I hope. The 2 part is just much easier for me.

Now what brand of Kalk mix did you use. The red sea stuff reverses the polarity, and is used when needed IIRC.

This sounds intesting. What polarity is reversed? The polarity of the water molecule?
I haven`t been up up new products lately?
