Swapping from Kalk to dosing pump

dmcoates · Oct 27, 2017

Hey guys I have a few questions.

I have a 100 gallon mixed reef heavy on sps. The total water volume including the dump is about 95 gallons.

I have been using a saturated Kalk water in my auto top off. I will evaporate about 1-1/2 gallons per day ( 3 teaspoons )of Kalk per day. That was not really keeping up with the tanks needs and I had to add about a teaspoon of soda ash mixed in RODI water per week just to maintain 7.5 DkH.

CaCl is also running a little low 410 ppm.

I mixed 2-1/2 cups of CaCl w/1 gallon of RODI water
And 2 cups of Soad Ash w/ 1 gallon of RODI water

So my question is how much of each should I start dosing per day with my dosing pump.

Thanks

On this calculator, use the entry for Randy's Recipe 1 to determine the dose of the alk part needed for a particular boost, and dose the same for the calcium part for routine use.

If you entirely stop the limewater, you'll need about 125 mL of the two part per day to replace it. Use that as a starting point, and adjust as needed based on the alk measurements.
