Review on H2Pro Wavemaker 4227Gph Aquarium Controller by Victoria Turner

The value is obvious. A very strong current. There's a buzz, but no more than other pricier brands. Programming is a bit complicated, but the basic Wave functions are done at the push of a button. It's easy to set the frequency and intensity of the wave in programmable ranges. The only thing I would like to change about this product is the ability to set longer intervals between pulses. The longest pulse interval is about 3 seconds or so, I want to be able to pulse for about 10 seconds.
