Good evening R2R! I started in the hobby in 2016 with a 29g BioCube. Quickly fell in love with what I was doing but even more quickly, ran out of room in my nano. I kept my eyes peeled on craigslist, facebook market place and other sites for a used tank as my next tank. What I found was a 150g tank with a 55g sump and a custom built stand. I had to modify the plumbing for the system and after 3 months I've been able to get my tank up and running. I'm very excited for this next chapter in my reefing story book and looking forward to watch this tank grow and evolve over the next few months and years! Here is the equipment breakdown; Tank - 150g glass tank drilled for sump Sump - 55g 5 chambers Bean animal overflow Lighting - (2) 32" LED black box lights Heaters - (2) 250 w aquatops (1) Titanium Heater 800w Skimmer - Vertex Omega 150 Powerheads - (2) vortech MP10ES, (1) eflux 2100 gph (1) eflux 660 gph RO/DI - 4 stage 75 gpd system Reefkeeper Lite Plus Control Center I'm not currently using an ATU, is that something that would be highly recommended? I'm going to be adding some bacteria to help speed up the cycling process but will still take things slow as I go! I can't even begin to think of a stocking list so please share your favorites with me!
