Took off tank to clean media, was working perfectly. Cleaned media and reassembled , couldn't stop the canister from leaking around the seal. Tried several attempts with no luck. As far as I'm concerned it can't be anything other than the seal it's all seems in perfect condition.
Would have ordered seal kit but it's a big filter and I really struggle to pick it up and carry it outside, so have decided to put two smaller filters on , this will be easier to handle for me. It's only been running for 17 months on an Oscar tank it's very powerful and was using return pipe to drive a large trickle filter.Comes with pipework taps sponges and poly wool the way it WAS going to go back on. I have tried to be as honest as possible. I don't know if I have lost a part of put it together incorrectly. On further inspection the water seems to be getting in the top chamber an leaking over the top of seal. PS the heating element has never been used , I prefer to use internal heaters on a separate timer.
I found the problem , I hadn't tightened the diaphragm ring tight enough.... Had it runnig outside for 3 hours and its perfect. But its still for sale as ive bought 2 smaller filters to replace it.
