It looks like the inflow also has holes drilled at the bottom. These look pretty awesome, wish they made em in glass.
Yes it still works. Actually it works the same way as Hagen/Fluval/Tom plastic surface skimmers.If the water level gets below the skimmer, does the inflow still work or does it lose its suction? Anyone with skimmer experience?
I have my lily pipe about 3/4 under water and keep the water level topped off. Feels like I can run the CO2 a bit higher because the oxygenation is better. Nothing quantifiable though.I have been running glass lilly pipes. I have dealt with bba problems which I believe is from the water level dropping and me having to adjust the outflow to increase surface tension to get rid of the eventual oily surface. It takes a week for mine to be an issue.
What I have been doing is I lowered my outflow as low as it will go. Run the Vuppa, which fixes the surface oil problem and keeps my co2 concentrations more stable than the lilly pipe.
How have you been doing it? I would like to have less equipment if possible, but the water evaporates and I keep having to move my lilly outflow.
