Nick, I ordered the kit you linked to and hooked it up. The mold-a-holders are really cool and the float valves work like a champ. I picked up 2 Tunze Osmolators as well (approx. $169 new on ebay). I'll be using them with the kit's float valves as backups, with one for each tank. For now my 90 is running on the DIY float valves and it's working great. Great recommendation.
Ed, I'm really torn on the controllers. I've been reading up on them and there are lots of good ones. My favorites so far are the Aquacontroller, the Biomatrix (recommended by Tbone) and the Profilux (after you suggested them... very impressive). BTW, there is a really good comparison site for aquarium controllers. I apologize for not remembering the name of the guy who put all this together, but he deserves a medal. If you are thinking of a controller, this is THE place to go:

On another subject, I'm getting a bit worried about having over done it on flow. After listening to everyone, I decided to bump it up a bit and I started picking up new Tunze's on ebay while also looking for stronger closed loop pumps. I've since picked up:
Tunze 6101 = 3170 gph
Tunze 6101 = 3170 gph
Tunze 6201 = 5284 gph
Those should give me up to a max of 11,624 gph. In addition, I'm just about to pull the trigger on:
Reeflo Dart Gold for the sump return = ~ 2,800 gph (due to head)
Reeflo Dart Gold on Oceans Motions closed loop #1 = 3,800 gph
Reeflo Super Dart Gold on Oceans Motions closed loop #2 = 4,300 gph (same as a Barracuda!)
Total = 22,500 gph, which on a 360 gallon tank = 62x turnover
Granted, these wont all be "on" at the same time. They will be hooked up to multi-controllers (I have a 7095) and/or timers (probably via one of the controllers discussed above). I really like that the Gold series are (supposedly) quieter, but should I be worried that this might be too much flow?
