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.
I was under the same impression. I actually came across the DCS pump during my research of the DCT, made plans to get it, and then came across the DCP, before I ended up buying the DCS.
From the few reviews I found of people that had both, they say that the high whine that the pump has higher up the power curve is much less than with the DCT, and DCS. I'm extremely happy with mine so far.
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.
I would say it does. My DCP 8000 is rated at 2113gph at max power with zero head height. My old RIO 20HF was rated at 1290gph under the same conditions. My head height is about 50-52", plus a little more due to some bends and a 3/4" bulkhead. I estimated that it was probably pushing 750-800gph, and that was at 65W. My new DCP 8000 can pump the same water on setting 57 out of 100, which it displays 34W on this setting. I know it's the same amount because I didn't change my herbie overflow at all and this setting put my water level exactly where it was with the other RIO pump.
I especially like that I can make such small adjustments to the pump speed because it really helps with tuning the overflows, instead of needing to make such tiny adjustments to the valves (I do have regular pvc ball valves instead of gate valves though).
