I am constructing a new brood stock system and I am trying to figure out what pump I need. right now its between the Sequence manta ray and the tiger shark My system will have 20 20 gallon tanks and aqua c ev 240, 25 micron filter, current gamma 120 watt UV sterilizer and a bio ball tower with 2 cubic ft of media. So i need a pretty big pump. I would like my turnover rate to be at least 10- 15x per hour per tank and run all the filters but the skimmer.
