HELP, my canister filter is leaking on the locks edge. anybody who knew how to repair this.
makati area here.

thanks

what type of canister filter do you have?

When I was into freshwater aquariums, I used different canisters, a whole slew of models and sizes.
I commonly encountered leaks from lid sides and they mostly were caused by two things:
- Cracks on the lids or the canister body(water pressure or maintenance blunders, drops, etc)
- failed O-rings, they fail at some point - some faster than the rest

what I did,
- cracks, if very small cracks I fixed them with a light spread of silicone. Big cracks I once tried epoxy, but they rarely last.so bili na bago
- for O-rings, if the damage is not visible or can't be felt by the touch(look for cracks, breaks, etc) I apply petroleum Jelly all over the o-ring and they work good as new.note though, you have to add petroleum jelly everytime you clean/open the canister filter. if you can find a silicon lubricant, that works even better supposedly.
- but if the damage is severe on an o-ring, chances are you would have to find a replacement part. some china brands don't have spare parts. my eheim canister does so nakabili ako kay A1.

hope this helps!

hi Bro Jobseclan,
firstly, thank s on your very informative response. I think my filter is Eheim also, am posting a
pic just for your reference. I might try the petroleum jelly approach first, but I will still be seeking
to replace the O-Ring that you had mentioned. What store nga po did u buy the replacement?
This setup nga pala is in my office in Makati.

most likely naman that the O-ring is the culprit.

thanks a lot and happy weekend.

No problem bro!
try mo si A1 Pet Center in Cartimar, if they don't have the part in stock, they can order.

not sure if they repair, parts lang most of the time tinatanong ko.
may maliliit na cracks or splits na siguro yung O-Ring kaya di na kaya ng petroleum jelly remedy.
if it's been a long time, probably time to change the filters?
