Drilling Established Tank

[silentcivilian]

Locally, I bought it at oceans city off 16th

And ill add, there are a few videos on youtube you can check out that show people unplugging the system.. showing you it doesnt lose the siphon, and re-plugging it back in to start working as it should.

They can still loose siphon, air bubbles can still build up in the tubes eventually breaking it. You also have to maintain a certain flow rate per siphon tube for them to work reliably.
