Ok I’ve got my new 365G tank being delivered in 4 weeks and I’m finishing-up getting everything ordered for the tank. Lights, return pumps, controller, plumbing parts, reverse osmosis, and heaters are all purchased. I’ve been taking advantage of all the Black Friday sales this week. Now I’m focused on media reactors for bio-pellets, GFO and carbon. Which brand/model would you recommend I research. There has been nothing so far on this tank where cost has been a constraint. Thanks everyone!
