edsbeaker: I think the reason there is no listed GPH is because it would vary based on how much air is introduced and other factors like depth. Many skimmer pumps including the RD only show air intake (lph) rather than GPH. If you want to roughly figure your GPH try allowing the output of the skimmer fill a 1 gallon container and time it. Figure out the GPM and multiply by 60. However no skimmer will ever capture 100% of the overflow water unless it is designed to have the over plumbed into the body. To prevent reskimming I direct the skimmer output away from the direction of the intake pump, while directing the overflow water as close to the pump as possible. It is still better to end up reskimming than to have the sump flow so fast it bypasses the skimmer.
Thanks, that makes sense.
