Interesting. I guess we'll see what happens over time here. I think going skimmerless is my new operation based on what I'm seeing. But we'll see, I'll continue water changes for now and see. I have it setup so a water change takes me less than 10 minutes. Open valve, drain into floor drain. Close valve, open valve to fresh water, plug pump in and fill sump. Shut off mixing pump and go.Purigen basically does what a slimmer does. Bonds up organica so they dont break down Into nitrates in your system . Doesnt help with gas exchange tho
Not quite an AWC, but pretty close.
