Calcium Reactor & Low PH

[Restless10101]

Hello everyone

I have a potential problem that I hope someone help me with.

I have been dosing TLF C balance in my 90 gallon reef tank, and I am now dosing just over 50ml / day and I am still having a hard time maintaining my calcium levels. The cost alone is making me think of other alternatives. So, I have been thinking about switching over to a calcium reactor. I have heard that the Co2 can lower the PH in your system, and hence my problem. Currently my PH peeks during the day at 8.1 and at night it goes down to 7.9. If I do switch over should I be looking for a calcium reactor that has a attached media reactor for kalkwasser?

Any thoughts are ideas would be greatly appreciated!
