I have toyed around with the idea of switching to kalkwasser from 2 part on my SPS frag tank. Demand is relatively low so I think it would fulfill my needs and I would like to dose from my BRS 1.1mL doser if I do switch. It's odd to me that I can't find any information relating dosing saturated kalkwasser in terms of alkalinity but I assume that is due to the fact that most people use it in top off situations.
I'm curious though if I make a saturated solution of limewater (ie 2tsp/gallon), then let it settle can I calculate how much I would need to dose of this solution every 24 hours to keep alkalinity stable? I'm not sure if the amount of dissolved kalk in this solution would be consistent through all temperatures, elevation, etc. that is well beyond me.
I would likely use BRS Kalkwasser but from Seachem's website it says adding 1 gallon of saturated kalkwasser solution to 40 gallons of aquarium water will increase calcium by 24mg/L. Since 1dKh is equal to 6.4-7.1ppm Ca I'm assuming I could use this to calculate a starting dose? Anyone see any issue with this? I can do the math from there but I'm surprised I haven't seen a calculator relating this.
Really for me the most important thing is keeping alkalinity stable but I would like this tank to benefit from an increase in pH to hopefully fuel coral growth.
