Q: Can you provide a link to purchase replacement lid for add on canister. I purchased last week and during my install the screw on snapped off in the lid. I need to purchase another.
A: We do not have seperate lids, they are made to fit the canisters. We pressure test each unit/canister to make sure there are no defects. With that said; you can sometimes get the threaded part out of the lid. Try a flat head screwdriver. If you are not comfortable doing that http://www.aquariumwaterfilters.com/Clear.Canister-p.cc.htm
I hope this helps
