Low tech with Airstone

I have a 90 gallon, heavily fish stocked and moderately planted - 1 giant Am Sw, a foot long area in back with Val's, several Javas, 8 crypts.

It's also low tech, no CO2.  I have pretty good surface agitation.  My question is I think of adding an air stone.  What's is your opinion please?

I have 2 Tidal 110's for extra filtration.  So I have surface agitation. So the extra air/agitation won't hurt my Co2 levels for my plants?

Air stones never hurt CO2 levels in low tech, and especially in tanks without injected CO2, they actually help with it. The only CO2 you have in the tank with no injection is what the fish produce (next to nothing generally), what the plants themselves produce during lights out, and what you are pumping in with air/surface agitation. So more surface agitation actually equals better CO2 in that case.

As long as you’re moving enough water, you’re good.

That can be via an airstone, hob, canister, etc.

I’ll throw an airstone in a tank if I specifically want to ensure higher oxygen levels for a specific species, or if I’m using an air driven filter.

They are never detrimental and always helpful to have.
