Here's my Red Sea Reefer 250. I only used this system 1 time as an observation tank for my 300g. I was told I was crazy for buying this just to use as an observation yet I had tangs I wanted to watch before putting them in and to me this was the easiest way. Haha. Letting this go too. Equipment is Red Sea Skimmer , Tunze ATO pump, Trigger System 19g reservoir, Reef Octopus return pump, 2 MP40s, Ecotech xr25 pro light. I'll either sell as a package deal or without equipment..
