I tried the psk2500 on my G3, it totally blew. I have the exact setup you linked sitting in a box. I have tried numerous pumps for my G3, the Sicce, Ocean Runner, Laguna 900 and 1500 and nothing performed as well as the Sedra. The Sedra 5000 is the right balance of air and water. I have not tried the new PSK1000 but it would be a better fit than the psk2500. My G3 is recirculating, which would make it easier on the pump, no head to overcome, and the psk2500 was not able to get enough air into the skimmer. I really wanted to get away from the Sedra, but in the end it is still the right pump for the G3 body. I have a box of skimmerpumps, if you want to try the Sicce for yourself, go for it, but don't use the 2500.
