Why choose a  Coral Box Skimmer?

Factory direct to the end user, while other brands go from the factory to a distributor, shop and then the end user increasing the cost to you.

Great product!
I had purchased this skimmer for my 125 reef tank. I have it in a 40g sump and is amazing. After a few days of it being broken in the amount of skimmate is unreal. I'm pulling out more with this skimmer than I did with a reef octopus 100g skimmer which was too small for my tank to begin with. Definitely worth the money!
