The wireless function on the Vortech pumps only functions with two pumps. Two wireless wave drivers (controller) can communicate back and forth creating different, programmed, wave patterns. With one pump, it is still hard wired to the controller. With one pump, the controller can speed it up or slow it down at various times.

I have 2 Vortech pumps on my 90 gallon. I purchased them before the wireless controller feature was available, but was able to upgrade to the wireless controllers, and just recently did so. Prior to that, my pumps were being controlled by my Neptune Aquacontroller III. I love these pumps!

IMO, there is no better pump on the market. One of the nice things about them is that the speed of the propeller can be manually adjusted from a slow gentle stream to hurricane force turbulance with the twist of a control knob. It is an ideal pump for 55 gallons!

Flow and using RO/DI water, among other things, are both basic necessities to good reef keeping. First you have to decide, is it worth it to go to the LFS for your water once a week or so, or do you want the convenience of having it at your finger tips. Secondly, flow can be created in many different ways and doesn't have to cost so much. You can get the Aquacontroller Jr and 2 Korallia pumps for the price of one Vortech pump.

Also, the Aquacontroller is a great instrument. It can do many things. You may want to design your tank around the Aquacontroller and only purchase equipment that does not have its own controller.
