I used Aquanic 3000, Dyna 3000, Eh 1262 and Eh1260 on 4 identical OHF setup , all with 40mm x 2 holes customed discharge outlet on the 2" height Base Plase.
Notice the below OHF base plate the water level Aquanic 3000 it is much lower at 60%. Dyna 3000 , Water level 75% to the base of the OHF boxes. Eh 1260, Water Level 80-90% of the Base plate Eh 1262 Water Level Already 95% The Water level raise that high also because the discharge adapter screw thread... Thus Aquanic 3000 fare much lower in term of headloss, as it is powering up a 5x2x1.5, where as Dyna 3000 is powering up a 5x2x2 . Both OHF are the same 4 Tier.

Thank Bro Humongous for the pictures and comparison. But I'm still not clear from the pictures and elaboration. Able to be a bit more detailed? Pai seh...

conclusion, Lower Better Aquanic 3000 (5x2x1.5) Headloss - Mid high Noise - Mid (Humming) Vibration - High Water Temp 28.5 Dyna 3000 (5x2x2) Headloss - Mid Noise - Low Vibration - Mid High Water Temp 27.3 Eh 1260 (5x2x1.5) Headloss - Minimal Noise - Low Vibration - Low Water Temp 29.4 Eh 1262 (5x2x2) Headloss - Minimal Noise - Low Vibration - Low Water Temp 29.7 Last edited by Humongous; 15-10-2013 at 04:35 PM. |

Mo recently just purchased a Rio Hyperflow 14HF. Measured by eyes based on tank height my tank set with sump is about 5 ft high @_@. So it should be about 1.5 metres. The specs on Rio pump box indicated a headloss at different height of the tank at 1.8m, the flow rate of that pump is around 2050L/Hr. If I'm not wrong the flow rate for this model should be around 3000++ L/Hr? Maybe some bros here can enlightened me. So far I have an eheim flexible hose at half a metre long connected to piping at sump there in a swirled U or S shape. And it bend out to the cabinet and bent up again to the main tank slanting around 60 degrees up. The water flow is still quite strong. I wonder how bro Humongous measures the flow rate of each pump reaching certain height? Néed to be enlightened to master this skill |

I did not measure the flowrate, bur observe from the level water present in the OHF base plate.... so see how it fare at different height where the pump being placed. |

I see that needs "Lao jiao" (hokkien) also known as experienced hobbyists to gauge the correct flow rate without measurement
