Hi all,

I've been thinking about the type of filter I'd like to use on my Dennerle 50l scaper tank, I recently bought the scapers flow filter designed for it; but found it to be far too bulky at the back. It has since been returned.

I'm now looking at either the Eheim Ecco Pro 130, Eheim Classic 250; or Hydor Prime 20.

Here are some main comparisons:

Ecco Pro 130 - £55, rated at up to 130 litres, pump head 500l (flow rate x 10)

Classic 250 - £43 rated at up to 250 litres, pump head 440l (8.8 x flow rate)

Hydor Prime 20 - rated up to 250 litres, 600l pump rate (12 x flow rate)


I have no experience with any of these canisters, only the Fluval '06 series; which I wasn't very sold on tbh. I'm drawn to the eheim classic 250, having heard of its reliability and ease of changing media etc; though the less than 10x flow is slightly concerning. I've also heard that on the ecco, the clips can break etc.

I don't see the tank having too heavy a bioload, its either gonna be cherry shrimps; a betta, or maybe a small schooling fish 7-8.

Welcome opinions 🙂

What about JBLe701.

9 Watts for 700l/hour, so about £12/year in electricity.

I have the bigger boy e1501 and is fine, no leaks, easy to take apart without flooding the place. Had since 2012.

I hadn't seen that one, looks like a good filter; I'd be slightly concerned with the flow rate though; the shrimp would love the high flow, but would likely rule out a betta 🙂
 
Flow rate can be reduced much more cheaply than it can be increased! You can always run it fully loaded with media and use a spray bar to evenly distribute the flow through the tank.

For what it's worth I have the classic 250 on a low tech 60x30x36 (60 L~) and found it to be perfectly adequate though flow does get reduced when it gets grubby. I think it more depends on if you're intending on injecting CO2, at which point flow becomes more important.

yeah I'll be running co2
 
Hello ! I have Eheim Pro 3 2071 on a Dennerle 35 litres; for aesthetic reasons I replaced the spray bar with a spin flow lily pipe; the filter have been running 24/7 since September 2014 with no hiccups; at that time it was a secondary filter for my RIO 300; it's completely silent; I would advise to steer clear from the eco pro range, which seems to be much less reliable

cool! Do you have pics of your set-up? I was very tempted at the time to go for the 35l instead of the 50!

I'll check out the pro 3 2071 🙂
 
Of course; check out my post " the force awakens"

I think the Eheim 250 and JBL e701 are not much different in real world use. Eheim openly show the pump head high data (the power of the pump to withstand clogging) while JBL don't. Flow rate alone doesn't really mean much in real world use but can be a powerful marketing tool.

This is from e701's manual:

IDLE RUNNING DATA of the pump, without hoses and filter material:
CP e701: 700 l/h
CP e901: 900 l/h
CP e1501: 1400 l/h
When operated in an aquarium, this data is reduced by different extents, depending on the length of hoses and the filter material used. An accumulation of dirt in the hoses and filter material will further reduce performance.
The following approximate capacities refer to a hose length of 1.5 m and operating with the supplied filter material in a clean or new condition:
CP e701: 350 – 400 l/h
CP e901: 380 – 450 l/h
CP e1501: 800 – 900 l/h

JBL don't as it is a completely irrelevant parameter as the pump is run in a closed loop. If one end of the filter was open then pump head height would be relevant.

You could place your filter on the floor below your tank if you wanted (say 4 m below) and provided you are operating a closed loop absolutely any pump will push water round. Not recommended of course, 8m of pipe will add significant resistance and there will be considerable water pressure at the lowest point of the system.
 
It is relevant. Because a pump with higher head height can create higher pressure. So it can pump water through restriction better than a pump with lower head spec. Otherwise manufacturers would all use wave maker pumps in canisters by now, 3000 LPH at 6w :wideyed:

You are confusing pressure and flow rate they are different. (volts, electric pressure, and amps, electric flow rate in electrical world). An isolated external pump needs pressure to produce a head height, a canister filter pump needs higher flow rate as it doesn't need to overcome head height.
 
They are different but pressure and restriction can affect flow rate. Otherwise the e701's 700 lph would not reduce to 350-400 lph in real world use. Pump head spec is there to show how well it can pump through restriction (gravity, bended pipes, CO2 reactor, in-line heater, etc.). It is very basic.

Please don't use the electronic term to compare it.
