Kalk or Calcium Reactor

[Billfisher]

Looking to dive into hard coral and need some good advice (Money well spent ) Looking for some ideas
Thanks All

Depends on demand... If you have low demand, Kalk should be plenty. If you have high demand, use both. Check out the chemistry forum for more (Money well spent).

I have never used a kalk reactor, but my ca reactor was the best thing I ever purchased. I dialed it in months ago and today I tested everything "first time in at least a month and a half" and ca was at 420 & alk was at 8.5. Simply perfect. Only thing I do now is dose mag every few days. Life is great now! No more constant dosing of two part. & other stuff. I just get to sit back and watch the tank grow!

Now I have a Kalk reactor and it works for me. I have about 80gallons with about 20 hard corals that take up cal. I do dose Clacite and Calcium Chloride to make up for what the Kalk. can not.

I will eventually own both when my calcium demand increases. The Kalk keeps my PH up as it is pumped in as the water evaps...about a gallon a day. The Kalk output has a PH of 12.4.

You can start out with a Kalk reactor, but once things start getting big you'll need to pick up a Calc reactor.

Bill,

How's your pH? If it is on the low side, kalk will help bring it up.

Add some dolomite to your Ca reactor in a ratio of 1:4 or 5 and you wont even need to do that anymore. :bum:

Yeah I know, but I have about 12 lbs of mag left from bulk reef supply I want to use up
