Finally solved my low ph issue.

My tank is now holding a steady 8.15 through the night and getting up to 8.25 in the day. It wasnt the fuge that helped me correct my issue. It was all thanks to a co2 scrubber. Went from a low of 7.65 to a low now of 8.15
Have it recirculating air from my skimmer cup. Now i just have to get my alkalinity back to 9 where i had it. Raising the ph has over doubled my alk consumption.

What fitting did you use on top of the skimmer for the air line?

Its from br . Its a kynar barbes fitting and i just cut the threaded side off and glued it in place i also drilled a hole in the skimmer cup lid that i slid the fitting through.
