Rena Canister Filters

Well it looks like you have enough LR but how much flow do you have, I dont like any filters on SW tanks I prefer LR good flow, refugium and skimmer. Canisters and hob filters tend to aid in high nitrates unless cleaned often so I would say get a good hang on skimmer and stop useing the hob and cannister filters or even better try to set up a fuge and add a skimmer in it.
