I have an oversized skimmer and a co2 scrubber attached to my skimmer, its had no affect on PH. Its winter here in Minnesota so I can't do an airline outside but I did buy a co2 monitor and the house is at 500 to 1000 ppm depending on how long we are in the room with the tank. The outside air when I put the monitor outside was at 400 ppm.
As for the jump in cal and mag the output from my dosing pump got clogged, its still definitely too high and have been backing off on the All For Reef. Below is more data, I slacked off on maintenance in 2022 in Dec of 2023 I started to pick it back up, its looking like all the large swings is killing the hammer. What I cant understand is all the other corals are growing like weeds but yet the hammers are dropping like fly's. The Tank is getting quite old, fish and corals are now 15 years old do corals die of old age?
