The new Jebao pumps using sinewave are great pumps. I have a couple with mybreturn pump and ATS pumps. They are powerful, quiet and so far reliable.I'm using 4 jebao pumps now. x2 DCP-8000 as returns (30% each), 1 DCP-6500 (60%) as the surge pump & 1 DCP-2500 (50%) for the algae scrubber. The 2500 has been running for 2 years, 8000's for 1 year & the 6500 for 3 months. No issues.
