Hi all. I’m not new to marine, but am very new to Red Sea max tanks. Also I’ve never run with a sump before so I’m tot clueless as to where to start lol. The tank I purchased was filthy but a good price and no damage other than one or two bits missing that the seller failed to inform me about. My first question is, it didn’t come with a return main pump so has anyone got one for sale or can recommend an alternative that’ll fit. I have got a spare jecod dcp 2500 , would this be any good,and will it just retro-fit etc. It’s taken me some time to clean the back chamber, it was really encrusted in there. So I look forward to any kind input, and thanks for the opportunity to post in here. Regards Paul.
