Hey folks, I need some help. I have an older Magnum 350 that I recently acquired. I bought new gaskets for the canister, cleaned everything and started the filter. That's when the problem started. The canister filled nicely but I soon noticed the water level dropping and found that the exhaust tube that is inside the canister is a bit short, the gasket there does not make contact with the lid of the canister. This is causing water to spray out into the canister. The agitation is causing air bubbles to form and slowly but surely the level of water drops to below half. This tube has not been altered. Has anyone else experienced this? If so what did you do to solve the problem?
