OK enough questions for now!

I have a Precision Marine Kalkreactor. Basically there is a big garbage can full of water, a Tunze Osmolator pumps the RO water from the garbage can into the input of the kalkreactor, then from the kalkreactor it flows through the output tube into the sump. I placed a check valve between the RO water container and the kalkreactor.

I got the kalkreactor 3rd hand from Sam who got it 2nd hand from someone else. Interestingly, OA sells their own brand of kalkreactor which looks identical to the PM kalkreactors except for a lower price. At first I thought this was just an amazing coincidence but now I attribute it to convergence in engineering, much the same as the evolution of the eye in completely unrelated species.

The kalkreactor runs off a Maxijet 400 powerhead.

Maintainence is: every few days fill up the RO water container, every month or two add some kalk powder to the kalkreactor, and every two or three months clean the kalk buildup from the output tube of the kalkreactor where it flows into the sump. Total maintainence is maybe 10 minutes a month max.

As far as Randy Holmes-Farley's article, I think he is wrong. I tried his method, then got a kalkreactor. Higher pH levels and higher calcium levels with a kalkreactor prove that I am dosing more kalk with the kalkreactor than with Randy's method.
