I want to know how many of you expierienced a leaking canister..I think that this problem a lot more common than I thought.Also vaseline does not always solve the problem as I have recently found out.Does warranty cover you for this?

i currently have a leaking c 360. when i first bought it about a month ago it would suck air when it was running and when it was turned off it would leak out water. so i contacted marineland and within about a little over a week i got some replace parts. i put the parts on and it now leaks constantly easily well over a few gallons a day. so i emailed them again and am now waiting for a reply. overall i would say that the c series filter is a poor design but i am impressed with customer service. if a filter is leaking the manufactur should take care of it under warrenty. i think that i am switching over to rena

I agree, the o-ring is usually the problem when they leak.
They just plain wear out after a while, so it's always a good part to have on hand.

What type of filter do you have?
I use Ehiems and they are pretty reliable, but if you need a source for their parts, let me know and I'll provide the link.

Wow freydo, I hope you can get that issue resolved.

I bought a cheap canister filter few years back, it was running fine on my 4ft planted tank. At first it does leak a bit but then it stop and running perfectly after that, been serving me for years. Recently the 4ft tank has been tear down and that filter has been used on a 2ft tank. Due to it was designed for 4ft tank, I had reduce the outflow to half of it, it was running fine for few months and then suddenly it start to give leaking problem, put some silicone oil on the o-ring, served me another month and it just kept on leaking. Bought myself a Eheim 2213 for the 2ft tank, put this filter to one of my 4ft gold fish tank, switched back the outflow to normal and no more leaking. I guess sometimes you might to check if the pressure is acceptable by the tank itself or not too.

It seems that leaking is part of the game.period.A good canister is a canister which does not leak and not one that keeps working for years.Who cares if you have to change a canister every 3 years?

I would be hesitant to use vaseline on rubber o-rings as vaseline can vulcanize certain types or rubber (same reason why you don't use it on condoms).

Most manufacturers (including Eheim) recommend silicone based lubricants.

As has been said, auto parts stores for spray silicone lubricant. You can also get it at sporting goods stores, I use it on bows and some gun parts, it has very little scent.

I do worry that the o-ring is damaged. If that is the case, I doubt spray silicone will fix it. I use it as a preventative measure only, to lube for assembly and not damage the o-ring. It is an extremely thin lubricant.

Leaks I have always fixed with vasoline until I could get a new o-ring.



And I must comment on the condom, we just had the plumbing reconfigured years ago to take care of that issue.

Buy a new filter.

Two things to do until then.
1. Latch the filter closed when it is empty. The fill the canister with water. It can make a difference.
2. Wrap the seam in waterproofing tape such as:

or

I've used the stretching Silicone Sealing Tape with great success.
