Wow, that sounds like a pain, and compounded by a bit of misfortune. I did some reading on them. Apparently the "recommended line" is used as a guide, such as where more emphasis is apparently put on not going over the mark, rather than attempting to stay on it. It's there so you won't push sand out of it by going too high on the pressure. I bet they had some complaints like yours so they went on to clarify that aspect in the write up.
The thing that got my attention is where they recommended two different pump types to pressurize them. One, a submersible pump like a Rio. The other is pushing it with a powered canister filter, like a Rena X2 through X4. I just happen to have a Rena X3, ahummm. :-)
I am working on building a natural tank, no pressurized Co2. So that got my attention real quick when they said that it tends to disperse Co2 into the atmosphere at the least of all bio filter types. Plus, from the animated gif I saw, they look pretty darn cool running. Not that I would care anything about that. ???
Thanks mucho for the reply though. Definitely gives me cause to take a step back and think it over a while.
