Thanks for the heads up man! I'm still tweaking some things. Hopefully all goes well. I was thinking about going with the g l a s s h o l e s, but heard they are somewhat noisy and you have to put some sort of material in there to quiet them down. I'm not a believe of putting thing in the overflow. lol Also, I didn't want to risk cracking my 180. :worried2:
AS long as you have enough flow though the overflow, they will never break siphon. Low flow will allow the bubbles to collect in the top of the u tubes until they break siphon. With higher flow, they get flushed right through never collecting in the top. I was worried when I first started using this type of overflow, but with enough testing the above info is what I found.
