Ok so me to the whole posting in forums thing lol, so forgive me if I don't do things to protocol and just let me know I'll change it but anyway this is my tank....it's a 100 gallon rimless with I believe about a 30 gallon Eshoppes sump. I have 2 AI Hydra 32 HD's on top mounted with the AI brackets. Just added Reef octupus 150int skimmer, a Tunze 3155 ATO. Have a MP40 stirring things up, and hoping to upgrade my return pump to a Vectra S2 and add battery backups for both those as soon as the Vectras are back in stock. Also I guess it's worth mentioning I have 2 65 gallon drums directly behind the tank in my garage as a mixing station, with a 75 gallon per day 5 stage RODI filter and dosing pump that does my auto water changes and doses my ALK and Calcium... Think that covers it...
