Low PH in aquarium

[mnl119]

If the air you're introducing is lower in CO2, it will increase the pH in the tank.

But a lot of the time, CO2 is elevated inside your home. In that case, more aeration just introduces more CO2, so pH will drop.

I doubt the ambient air inside the house will have more CO2 than the dissolved air in a fully populated FOWLR that's not being adequately aerated.

But aerating a tank with high co2 (1200+) in the house will drive it further down. 100%

I respectfully disagree. The air dissolved in the tank water came from the house in the first place. Add to it the respired CO2 from the fish and the dissolved air will have a greater percentage of CO2.

Very few homes experience >1200 ppm of carbon dioxide.

High CO2 Levels Indoors Will Surprise You

CO2Meter highlights a Carbon Dioxide (CO2) exposure limits chart and references ASHRAE, OSHA, NIOSH EPA, and more.

Indoor carbon dioxide levels could be a health hazard, scientists warn

CO2 in bedrooms and offices may affect cognition and cause kidney and bone problems

You better off to have a cover on your aquarium or not have the surface agitated if you have high CO2. It's also better to run an airline outside for your skimmer so you'll have that lowering the CO2 of your aquarium.

As many have mentioned.... in a non stony coral tank PH isnt the most important thing. Im certain you have high levels of Co2 in your home, which will cause your PH to drop. You could use a co2 scubber to help but there isnt much benefit to this...imo.

Alright I’ve heard that as well before thanks!
