I run a sea side aquatics cs-2, it's a cone skimmer that completely disassembles base comes off to get to pump so every 3 months it takes me like 20 min to scrub it down and put it back in. latley it's been growing a lot of coraline so I may need to use extra strength vinegar soak it a lil. that stuff works fast like 10-15 min soak in a 50/50 mixture.
