Thanks for the link, mc. I'll check them out at the hydro shop to see how loud and hot they are. The outlet looks really small for such a large pump. I'm adding a ton of DO through all the water movement (drains, waterfalls, stream pumps, air stones, etc.) that I think I can get away with what i'm using for now. I don't think I can truly take advantage of it all till I have more light anyways. There's a balance somewhere in there lol.
13 Dawgs are gonna be germed soon :) In 6-7 months I should be ready to run them in the mpbs...gotta find moms first. That should give me 2-3 runs with the mpbs to get familiar with how it all works and to get things more dialed in. I'm really glad I built the mini-mpb system for veg cause it's basically the same thing and was very helpful in getting me ready for the big step up...both in construction and growing. I would recommend anyone to experiment a little first before going all out! A lot can go wrong if you're not on top of it.
