Hey all,

So we have the chance to switch our 3 big tanks over to canister filters. We currently have HOBs. My biggest concern with the canisters is with them leaking, and consequently flooding the floor and/or draining the tanks. Am I being paranoid? Is there some sort of anti-siphon system we should have in place? Although my understanding is that most of the canisters work on a siphon to get the water to the filter, so not sure how practical that is. We are getting Rena/Filstar XP filters.
