Hey SDReefs,
I need some help maintaining a higher PH in my tank. It maintains between 7.7 and 7.8 with the occasional 7.9 reading.
System is ~110 gallons
S.G. 1.026
Alk 7.8
Calc 500 (I know this is high, doing a wc today to help balance it out)
Nitrate 15-20
Phosphate .15
I'd like to keep it at a higher PH to help out sps growth. I started supplementing kalkwasser along with my two part dosing since I was a bit low on calc/alk anyway. I started a couple of days ago with 2 tsp in a 1 gallon jug, dosing 125 ml per day. I'm pretty sure this is not even close to enough to make a dent.
Would I be able to increase kalk concentration without a kalk reactor or should I continue this way and just increase to 500ml or more?
I'm trying to avoid using it in ATO so that it's more controlled and doesn't gunk up my reservoir.
Appreciate any other tips or advice you may have for increasing PH.
