Would y'all recommend I run my Eheim 350 skimmer at night or as slipfinger suggested he does on his 75g "weed farm" for: "half hour runtime multiple times a day" (https://barrreport.com/threads/75g-dutch-weed-farm.14313/). I've been reading posts where Tom emphasizes again and again CO2 levels such that I'm thinking I'd better attend to any surface agitation. Then I saw slipfinger's statement that he has his skimmer on a timer and thought this a good idea. I can't imagine either timer choice would be significantly superior or inferior, both should help, but I thought I'd solicit opinions before I setup my timer. 12hrs on and 12hrs off or say 30min on every 2 hours? Or maybe someone might suggest this skimmer has little to no impact CO2 levels?
thank you
