I wrote this on another site I frequent and thought I would share. I did a search here and didnt see that I posted it before. I hope this helps someone.

Everyone that knows me, knows I am a huge Eheim fan. I use them on all my tanks. Generally I am a "Classic" Eheim guy and few months ago bought a Classic 2215 for my 29 Shrimp tank. Well, for the first time ever, the filter died. So I was off to get another. I had purchased it from Petsmart and to my horror found out that they are no longer carrying that line in store.

I have never been very excited about the ecco line. I printed out the Petsmarts online price for both the ECCO 2234 and 2236, packaged up my 2215 had headed off to the Petsmart.

They had them both in stock. For those who are not familiar with the line the:

  1. 2232 is rated for tanks up to 35 gallons and pumps 127 gph
  2. 2234 is rated to 60 gallons and 145 gph
  3. 2236 is rated to 80 gallons at 185 gph.

I was torn between the 2234 and the 2236. Considering this was going on a 29 it should have been a no brainer. I should have just went with the 2234. Well, I didnt. I went with the 2236 because with was the price match brought the two to exactly the same price and it pushed 20 gph more than the 2215.

Setup was a snap. The disconnects are integrated into the motor housing so no measuring and cutting. There is no spray bar, just an adjustable nozzle. I filled one tray with the ehfisubstrat from the 2215 I just exchanged and filled the remaining baskets with the ehfisubstrat pro that came with the ECCO then placed the unit in the stand under the tank, attached the intake to the Eheim prefilter unit I bought and cut the tubing to fit. Next I attached the return line leaving it uncut and long for the future DIY CO2 reactor I am going to build. I then pulled the priming handle down and the canister started filling. Once filled I pushed it back up locking it in place and then plugged it in and it fired up. Lastly I used a couple of the suction cups to lock in the return and then fiddled with the return nozzle. It creates a perfect little vortex on the waters surface just like those $100+ ADA Lilly Pipes!

I am sold!

Here is a picture of the Eheim Pre-filter I use:


I am using this because it is a RCS colony. This sucker is cool and only $12.99! The replacement inserts are only like $3.99 for a pair and completely reusable.

Pros:
1: Extremely easy setup - took me all of 15 minutes start to finish. Those not familiar with setting up a canister might take twice as long.
2: Comes complete with everything one would need to get this running, including Eheims best biofilter media.
3: Incredible price. the 2232 is 69.99 2234 is 84.99 and the biggest 2236 is 94.99 with online price match at Petsmart. These were the prices when I bought it and originally wrote this review on another site.
Cons:
1: Flow. Eheim rates their canisters by the amount of media, not the flow amount. The 2236 is rated for tanks up to 80 gallons. I have it on a 29 and the flow IMO is perfect. I couldnt imagine it on anything larger. You would have to use secondary pumps to get the correct flow.

Eheim Site said:
The EHEIM Ecco canister filters offer three stages of long-term filtration (mechanical, chemical, and biological) in an easy-to-set-up package. The multifunction handle, with worldwide patent-pending technology, is unique to the EHEIM Ecco filter. In addition to locking and unlocking the filter and use as a carrying handle, it functions as a priming device. After simply connecting the intake and output hoses, and arranging your media baskets, move the multifunction handle down to the start position. The water flow will begin. When the filter is full, just plug and play. The filter comes complete with media, fittings, and valves. The convenient interlocking media baskets allow for versatility in media setup while preventing water by-pass. With proper media setup, a long service life can be expected, on average 3-6 months between cleanings. The intake and output hose attachments are designed to swivel 360 degrees to ensure kink-free hose connections. A silicone-based integrated o-ring ensures leak-free secure operation. With a new handy impeller cover, annual impeller maintenance could not be easier.

As with all EHEIM canister filters, the Ecco impeller drive is outfitted with ceramic shaft and carbon bearing to ensure silent operation. EHEIM hermetically sealed motor technology guarantees efficient low-energy consumption and safe operation with a long-life expectancy. For fresh and saltwater aquariums. Made in Germany.

I have been evaluating a pair of 2235s myself for the last few months.One continually.They may be a lot of things,and have some fine features but the ecco line definitely falls short of the Classic.

My check valve,ball,had to be removed because I couldn't stop it from rattling.It still is not as quiet as my Classics are.

These filters can be overdriven by employing the 6 blade impeller assembly from a 2026-2028 Pro II,however this provided a minimal gain in performance.

ecco 2235 factory configured*

140gph.

ecco 2235 2026-2028 impeller assembly*

Is the bottom of the prefilter solid plastic or are there inlets for the water? I'm asking about the bottom part of the prefilter that rests directly on the substrate.

What is the diameter of the prefilter part? I'm not asking what size tubing is needed.

Thanks!

I have been using Eheim canisters for close to 20 some odd yrs, Generally I trust their rating for filtration capacity. Eheim relies nore on efficient water flow through efficient media when calculating what their canisters can handle. Most other manufacturers rely on pushing as much water through thier media as possible to determine tank to filter efficiency.

The 2234 would have been plenty of filter for my 29 gallon shrimp tank. There is no doubt about it. But if I ever decided to upgrade the tank size I would be looking at another filter. The 2236 holds 25-30% more media and with the increase in flow at only 20gph, I knew that it would not blow out the RCS. I also knew if I got a larger tank, I could simply use the same filter.

I am very happy I just went with the 2236.

mmk. was there some crazy sale going on at the time? the 2234 looks like it is 129.99 and the 2236 is 159.99 right now. if so, sounds like it might be worth waiting for a sale.

It is solid. ALL of the water enters the prefilter from where you can see in the image.

I've noticed that too.... seems like prices are quite erratic at this time. Look around and you can find them cheaper.
Definitely shop around. I have noticed when looking for other supplies that retailers put the ECCO's on sale all the time and generally at substantial savings.

Thanks for the info.

I was wanting to put a diffuser underneath it but it won't work. That is why I was asking.

thanks for the replies on cheaper websites. the thing is, my girlfriend gave me a $50 petsmart giftcard for a christmas present and i would like to use this towards a filter. petsmart's website still carries the classics ($105.99 + $6 shipping for the 2215). is that any better of a deal? i just like the way the ecco is designed more.

Today I just saw 2232 on clearance for $50 (normally $100) at a lfs. I have no use for it now, but was wondering if it was worth just grabbing at that price for future use.

I have a 46g with a fluval 305. Perhaps the 2232 could used as a temporary backup if the fluval needed repair, although that was my excuse for grabbing a whisper 10i and 20i which also serve as temp filters in 5g buckets when needed.

I also have a couple of 10g tanks with HOB filters. I'm fine with them. Seems like something around 20g to 29g would be the rights size for a 2232, but I have no plans on getting a tank that size. If anything, my next tank would be a 90g. :)

Thank you for a review. I was planning to get classic 2215 for my future 36" tank (40 breeder or 38g, I didn't decide yet) as a second filter (I have 2213 on my 15g which I want to use for my new tank) but after reading your review I may consider getting the 2236 instead. Can you do a quick comparsion ecco 2236 vs classic 2215?

Anyone with this filter have any issues with excessive humming from the motor housing? I just bought a 2236 for a tank i have in a living room and the resonating from the humming is very annoying and quite loud compared to a 2215 classic i run on another tank. Sound level is near that of a cheap air pump. Any help on what might me the problem? I've broken it down twice, checked and rechecked the impeller housing and making sure it was seated properly. Any ideas on what im doing wrong?
