I have a Sicce Syncra 5.0 (1321 gph) that I keep for a back up in case my Vectra craps out. You can use it till you can find one. (They are 204.99 at BRS)
That is what I have on my 125. I love that pump. I think I am going to buy something new today. I was hoping someone had a used one for sale before I went with a new one.
I went with a Lifeguard Quiet One Pro 4000 (1022 GPH) and a Lifeguard Quiet One Pro 6000 (1876 GPH). I found them on BRS so I feel a little more comfortable than I would if it were a Chinese knock off on Ebay. I plan on putting a food safe silicon mat under them to cut down on vibration. They should be here tomorrow. John
