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...

Pardon my lacking in the command of english....

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

Thanks for the clarifications, bro. So in conclusion Eheim is still the best choice?

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

This is how my Rio pump connected to the piping at the sump.

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
