I love my reefkeepers. I have the Reefkeeper 2 and the Reefkeeper lite. They work wonderfully. The reports I hear about the Reefkeeper Elite are great. Hope that helps you out.
I absolutely love my Reefkeeper Lite - I have 1 head unit up and its controlling 4 pc4's Does an OUTSTANDING job. You will not be disappointed only pleased if you get one. If you are disappointed you need counseling lol. For the price you can not beat these systems. Good luck
i have the older neptune - aquacontroller 3 maybe it might have a price break. I just ck'd MarineDepot The cheapest is the AC Jr @ $150 bucks. Neptune does make good products and well worth the cost. I use it with the two DC8's. It looks like a power strip but each outlet is controlled by the AController.
I'm a big fan of my RKL lite controlling my 125G and fuge. Now that they added the Net module to it, it is a great alternative to the RKE if you don't need all of the size of RKE.
