The overflow is not a Utube design - it is more like a "Calfo" style or "Weir" style with various baffles inside of it. It has worked flawlessly for 3 months without any issue - which is why there is a big concern with me..
Unfortunately just going back to the way it was is not an option - I woke up this morning to find my fish gasping at the water for oxygen - due to the lack of movement from just the two powerheads. I have thrown an airstone and a couple more powerheads towards the surface for now until I can get home from work. I will have to find a way to get the skimmer to work if this is going to be more than a couple days - either way this is frustrating!
The SEIO powerhead is constantly connected to the air nipple sucking from the top which is how I get the siphon to start in the first place..
Any other thoughts would be appreciated..
