Works Great By Dedeo on 7/6/2013Dedeo would recommend this product to a friendMy Marineland c360 canister filter was leaking and sending out millions of tiny air bubbles the 4th time is cleaned it. spent hours trying to figure it out. I emailed Marineland and they said I needed to lubricate the big Oring around the lid of canister. I said ''yeah right''. This stuff worked great. No leaking and no bubbles. The only reason I gave it a 4 star rating was because there were no instructions. This product works Great!!!!!!
Feel silly for not ordering before By Travis on 5/7/2012Travis would recommend this product to a friendSo I feel a little silly now for all the times I struggled and cursed at struggling to be able to open my RO canisters to change the filters! I should have know better but now that I do hopefully they won't be such a pain to open next time and if they're not I might have to invest in the larger size.
