Getting PH up on lg system with CA Reactor

[AJT]

I have returned my Vertex Libra & got a Geo calcium reactor. Of course now my PH is 7.8 at night & 8.1 during the day.

Bought a large aqua medic 5000 kalk reactor only to find out I cannot use it with a gravity fed (float valve) R/O system. Cannot pressurize the reactor, so its going back.

Thinking of just figuring out how much kalk to add to my 55 gallon R/O reservoir, put a power head in the tank & stir it mostly at night.


I have a PM kalk reactor but it is leaking around the maxijet & that scares me to repair & put on the tank....

Any thoughts??

What are other large tank owners doing??

Fresh air intake opening and vent to the outside works very well for me, along with a large protein skimmer. My calcium reactor is 12"x24" and runs a solid stream, my tank ph is 8.2-8.4. Fresh air is great for the system and helps reduce humidity.

Why do you feel your PH is an issue?

Good question. Everything I have read states 8.1-8.3. It may not be an issue, "chasing numbers"?

Protein skimmer gets air from outside.

As long as alkalinity, calcium and magnesium are within normal limits, I wouldn't sweat the ph too much. You can try running your calcium reactor effluent near the skimmer intake to degas the excess CO2.

Maybe it is your pH measuring device that needs to be upgraded first. Also, make sure you are measuring pH in the same place at the same time of day to compare results. Look to see if your measurements are stable over time before determining you need to make changes. Let your tank's health tell you if things are okay or are changing in the wrong direction(s) over time.

Effluent is dripping into filter sock with 2 air stones.

Measured with APEX, new PH probe, just calibrated, mounted in sump downstream.
