Hey Im a newbie to saltwater tanks but after having to part with my loved fresh water aquarium due to space , I decided my next set up would be a marine nano tank, which I have wanted to do for years. I have gone for the aqua one mini reef 90
I've never used a sump before and wanted to add some activated carbon but not sure where to place it. I have read of people adding to their filter sock, but I was just wondering if this could cause blockages?
