The reason for me to buy the AQLink was, because my contoller that came with it stopped functioning properly. It has a learning curve and i feel like it is limited. But, it is one of the first line powerhead controllers. I cant wait to see the newer models and what they offer. Anyways, the product worked like a charm. It does what I need and a little more. Before I had it, I would have debris that would collect on the top corner of my tank and I would have to keep puahing the 'Fred's button so the powerhead would stop and would allow the debris to overflow into my sump. Now, I just have it scheduled and I use the gyre setting to allow it to stop the powerhead multiple times daily. I like it and reccommend it. It is neat and adds a little more control to the tank.

Has all the features to make a nice random flow in the tank. Was a bit hard to connect to WiFi at first, but once you have them set up I leave it to the programming to make a random pattern which the corals love. Sometimes I can only connect to one at a time, but easy enough to switch by disabling and reenabling wifi standing closer to the one that I want to control. For the price the features are unbeatable.
