Saltwater Aquarium/ Fish Tank - Innovative Marine EXT 75 Gallon Reef System – Black - selling for 1150 OBO. I’m selling my EXT 75 Gallon Saltwater Reef System. It has a sump and it’s been professionally plumbed. It’s never had any livestock. I was going to get into the hobby and decide it was not for me. This is the list of extras I have. Some of it hasn’t been used. Some of it has only been used for a month. The live sand and the rock have been sold. I can sell equipment separately as well. 2X - XStream Wave Pump (925 GPH) Osmolator 3155 Water level controller by Tunze (Automatic top-off) ConeS co-1 In Sump protein skimmer Prime 16HD LED Reef light (Black) Crystal sump 30 Trigger Systems 5 stage premium plus 75 GPD RO/DI System 200w titanium aquarium heater and WIFI aquarium heater controller.
