Didn't know they came out with newer pumps, thought the DCT models were pretty new too. I guess they weren't as new in asia as they were here... Thanks for sharing.
Do you find it moves as much water as marked? That was one thing I wasn't sure about. It seems mine is a little weaker than I had expected. That said I am also using the 10000 to push through two large cartridge filters so I know that slows it down a good deal.
So a heads up for larger sizes than the 10000 model, I contacted Fish Street, they seem to be one of the main companies carrying these pumps. They were surprised hearing about a 20000 size though did say an 18000 model is coming. I've asked for some more details, hopefully it'll be able to handle some head no problem as I'd like to use it as a basement pump.
Still, even 145 and 175 watts isn't terrible for that kind of flow and head. Right now I'm using a Hammerhead, it uses a bit over 300 watts and puts out a bit over 6000 GPH with no head. 175 watts for 5200 GPH would be worth it, especially depending on the price of the pump.
Interesting Fish Street is saying there wont be a 20000 but there will be a 18000.
