Low PH help!

renato120 · Sep 30, 2015

Hi! Im having a problem with low PH... Tank its in a basement and there is no doors to open, just a small window... Im using a hose from outside to the skimmer, but it didnt help... PH its at 7.8 on day light..
I can't keep the window open at all the time. I have to close when Im not home... Any other trick to make PH higher?
Thank you

Using a CO2 scrubber on a skimmer inlet, or limewater for calcium and alkalinity are the best options in such a scenario if you cannot bring in more fresh air.

What is a co2 scrubber? I already have a hose from outside to the skimmer inlet.. Is that what you are talking about? Thank you.

The hose can help, but a CO2 scrubber is a filter on the air inlet that uses a media that absorbed CO2. So you can drive in air with even lower CO2 than outside air.
