Looking for a pump recommendation from anyone willing to offer one. Currently I have a recirculating G-6 with a gate valve. One of the three Sedra 9000's died on me and the others are fairly noisy, so I was hoping to replace all three with something a bit quieter without losing any performance. It's going to be going on a system with ~600g of water. I've been looking into the Sicce PSK-1000 or PSK-2500 and some of the Bubble Blaster pumps, but was just curious if there were any specific recommendations. Any help would be greatly appreciated.
