View Full Version : 120 Reef Schematic - Kalkreactor Question

01/15/2008, 09:11 AM
Hi! Wondering if it will be safe for me to add a kalkreactor directly off of my RO unit that comes on 3 times a day and tops off tank....

So, my guess, is around 1/2 a gallon of kalkwasser will be dumped in over a 3 minute timeframe 3x a day....for a 120 gallon system.

Any thoughts? Is this ok, or do I need to set it up to drip...which will involve a dosing pump ($$) and another RO water reservoir set up with a float valve....which I really dont feel like messing with ......

So, trying to make this a simple as possible.

I am attaching my reef schematic...would appreciate any suggestions.

The half gallon will boost overall tank pH by about 0.3 pH units or so instantly. That may be OK overall, but will likely cause the precipitation of calcium carbonate in the sump, where the pH will be far higher. I'd try to spread it out in time.
