I Agree with Tom R

I have been debating over a controller as well. The issue I have with Profilux is that to get a powerbar to control a few more things, I need to spend a lot more money.

Alternatively, the RK Elite will be completely new and possibly have a few bugs to work out, so anyone buying this will probably need some patience.

I'm still on the fence.

I'm holding out for the Biomatix

I,m happy with my RK2. But besides a Ranco temp. controller, its the only one I have owned, so no comparison.

This controller looks pretty cool. Anyone know anything more about them?

For basic tasks we created the ProfiLux II eX.

- temperature & pH-control
- dosingpump & currentpump control
- light control (standard or dimmable)
- PC-interface (RS232)
- up to 4 powerbars (with 6 sockets each) can be connected

this unit is not expandable

Please ask your retailer or Aqua Digital for pricing & details.

Biomatix Info
 

Yeah...the biomatix thing is pretty sweet. I think they have a media kit on there. I know its fully expandable. And they're selling them now if you call. There's a place in Houston called fish gallery that has one setup. If you google biomatix, you can find some pix of a setup at the Biomatix office from some guy's blog. The coolest part is all the remote monitoring features which they aren't "selling" enough. You can control the thing from your iphone if you've got one!

I have used the aquatronica unit for a year and a half and love it, I have a lap-top hooked up in my fishroom to make easy changes but everything can be done through the display. Simple to use and have had no problems. LOVE IT

I think, when it comes out the reefkeeper elite will be the bast bang for the buck. Lowest price most features.

Only problem with this as we all know...very few basic tanks stay that way :)
