red sea reefdose 4

Had this for a little over a year. Flushed the heads with RO/DI, factory reset, and removed from Reefbeat app, so it's ready to go. Asking $275 shipped. Please PM if interested. Thanks!!

Ended up buying two brand new red sea reef dose 4's for my first tank. Turns out I only need one. Looking to off load my extra one for $380.

Kessil H80 tuna Flora refugium light. With mount. $85 shipped. Works as it should. All equipment was purchased new. Everything else has been sold
