Kalk and CO2 scrubber not raising ph enough

[jimmypencil]

I know this is an older post, but that amount of kalkwasser is very low. If the goal is pH raising, you might want to add 5 times that amount. Even if all is added instantly, the pH boost is about 0.1 pH unit. Spread it out and the effect will be quite low.

right and my daily alk consumption is only .2-.3 dkh and im prioritizing alk stability. so i guess i will just have to wait until corals grow and demand increases to start dosing enough kalkwasser to significantly raise ph.

i recently moved powerheads and return nozzle so that they werent facing the surface (to reduce surface agitation) and this helped with ph a good bit.

Growing coralline algae will help increase consumption faster than waiting on coral growth. I have the same issue in that volume of kalk needed to materially raise Ph shoots my dkh to the moon.

Refugium looking to be my only alternative. Peg the light schedule to the ph. Off when reaching X value wanted. Until coral growth enough to resolve co2 consumption during display lights on

Coraline growth recently exploded so hopefully that helps. I want to do a fuge but i see best results with my sps with nitrate at 15+ and phosphate at .07+ so i dont want to be worried about my nutrients getting stripped all the time.

Fuge can be dialed in as well based on nutrient need or feed more and keep ammonium and phosphates always present. Going to be and is my approach. Can also dose nitrates and phosphates. Seems simpler to me to bottom something out then add back what’s needed vs trying to walk a tight rope trying to keep exact tolerances. It’s a hobby. Not space exploration.

My tank is under a window. I keep the window open with a fan blowing across. In the summer I have a window AC that blows air and even in the Winter which gets cold up here in New Hampshire I keep the window open a crack and this really helps my PH.

Yes.
