Hi @Geoffrey Rea @alto
I was following the thread below..
https://www.ukaps.org/forum/threads/long-term-filamentous-diatoms.61480/
... and in post #14 Geoffrey made an interesting observation regarding dissolved oxygen.
That an air stone or increased surface agitation could in fact reduce the over night levels of dissolved oxygen in an aquarium.
I didn't want to hijack the above thread, but at the same time this idea has now been banging around in my head for the last couple of days.
I'm hoping we might pick up where you left off.
I've been running an air stone from CO2 off to CO2 on in my tank to ensure enough dissolved O2 over night for my fish.
From Geoffrey's tests, at a certain point of plant mass / growth the air stone will be counterproductive in this respect.
Do we know how common this is? How much plant mass before you reach the tipping point?
My fish are fine with my status quo, but are there additional benefits of maximising over night dissolved O2 levels for the plants? Or for any other reason?
Testing for dissolved O2 doesn't look cheap, with meters starting at a couple of hundred pounds, and even test kits at the 40 pound range:

(And that's before international postage, customs issues and emails requesting Material Safety Data Sheets)
So before I go any further down this path, it would be good to understand the potential benefits of increased dissolved O2, beyond what it necessary for the fish?
