Eheim External Filters

[newton]

Hi has anybody done any comparisons on the differances between the eheim classic, pro and pro 2 and wet and dry filters to see if there are any huge differances in terms of performance as far as the fish are concerned for an average 200 litre tank

I am going to upgrade to an Eheim external filter but just wondering if there is much point in paying all the extra cash for a pro filter as opposed to the classic which is often obtainable at a quarter of the price

Many thanks

Classics are harder to work on, with no priming function or quick release valves. Taking the filter off for cleaning can in turn water the floor a little. Pro1's have an optional prime part, but it's a fair bit of faffing first start. After that maintanance is easier. The Pro2's have easy quick release valves and a prime function for ease of use. For your adverage tank, you won't see great performance differences, but the Pro's have greater surface area making them better for running on the limits of performance, due to better contact time. The wet and dry's will be most efficient at filtering on paper, but again you won't see lots of difference on your adverage tank

Shop arround, and the Pro 2's aren't that much more than classics, for that size tank at least. Mebe double the proce for a pro 2, about 50% more for a pro 1

I just picked up a 2224 for $65, and the thing is dead silent. Like put your hand on it to see if it's running silent. and when that doesnt work, you put your hand in the water in front of the output silent... Yeah, it's quiet. Gotta agree that getting it primed is a bit of a cluster if you cant get a proper siphon going, but the quick releases are nice for doing dry filter maintenance. Time will tell how much I like it, but so far, itsa niiiice. Supposed to be good for 65 gal US.

the classics dont have media trays

i wouldnt buy anything other than a pro1,2,3 unless you dont mind getting wet when cleaning

But getting wet is half the fun of keeping fish

Have to echo that my experience with my 2222 has been exactly as the others have mentioned here, especially the comments above.

It has been very nice to simply flip the little release lever and pull out the whole box with no water getting on things in my undertank cabinet. It is also very nice to simply lift out trays for inspection of each media type and quick rinse in tank water. Also the impeller is easy to inspect.

As someone who used to use HOBs, I've been amazed at how much easier maintenance is, despite the greatly increased surface area of media.

just another note on eheims, doesn't apply in comparison to other eheim makes but on the price difference between eheims and other cheaper filters like fluvals.

the reason they cost more is because they just don't break. they will run and run and run with no problems for years. so buying a cheaper filter is often a false economy cos 3 years later you'll be buying a better one anyway!

even pro eheims are a pig to prime, but they are, virtually silent, easy to work on and, seem, never to fail.

As I think about it, I think what I need to get is one of those big CPR squeezeballs to slap on the return line. One squeeze/release on that sucker should get it flowing... Anyone tried anything similar?


gotta be better than a mouth of fishwater

After a few mouthfulls you soon learn when to stop and get the tube out of your mouth.

I find that you only really ever need to get the syphon going once, after that shutting the valve on the quick release taps holds the syphon in place and you only have to open the valve again and water starts flowing again so its not really any hardship.

what am i doing then? even shutting the taps l still end up messin around to get it started

Prehaps you are letting the water level drop below the strainer on the intake so your syphon is broken?

cheers that makes sense. plus i may not have had the tops, on the installation set, screwed on enough.
