I recently bought a Periha pump which has similar output to my RIO 17HF. The Periha pump has three levels, I used the max setting at 50 watts as this setting was similar to the output of my RIO 17HF. After a couple of days, I experimented using the 30 watt setting and could not notice any difference in clarity in my tank. Does having more flow than rate required for clarity have any other advantage?
