no website on the manufacturers instructions, just their own that doesn't have a store.. i guess oceanic is more of an east coast brand I was told, and i am in CA
i have two pouches of carbon that i alternate between every week or so (someone on here suggested it), the sponges I have never replaced since the tank is only a couple weeks old.
I was just curious when I should replace the sponges and more specifically the little sliding carbon insert.. I assume it is carbon inside because when I ran it under water the first time black water came out.. but it doesn't say anywhere on the instructions if it is carbon and something else too.. I haven't taken out this "carbon" insert yet though, just alternated the packs
also, how often should I change ceramic rings?
sorry for so many questions, just want to get my maintence schedule down!
