Eheim 2075 Pro 3 Canister Filter - Up to 160 gal.

I have owned the 2075 for about a year and one night it just started leaking. Imagine my surprise the next morning when I noticed all of the water in front of the tank. It leaked several gallons of water overnight. I got lucky this happened on the weekend, it took a very long time to clean it all up.

Next I find the leak, an internal o-ring between the pump and the canister needs replaced. This causes the unit to leak at the power cord inlet. It didn't take long to find the leak, it takes much longer to get the part. Everywhere that sold these gasket sets had none in stock. I have an order in with Trilby Tropical. They tell me the gasket sets are on back order. I have e-mailed the company, they have not responded. That was 3 weeks ago! I am still waiting. I had to buy a new filter to keep the fish healthy. I could never own another Eheim product. That was a waste of $300.

I've owned an Eheim 2217 for many years and it has operated flawlessly. I recently set up a new 110 gallon community tank and decided to spring on the latest Eheim model the 2075. It's only been running 2 months so perhaps my impression on this will improve, but so far it's been underwhelming.

As others have mentioned, the priming button doesn't really work. YOu have to press the buttom 20+ times...just when you're about to give up and try to do it the hard way then it springs to life.

Second, even after a 50% water change, my water is still cloudy. It doesn't seem to help...although I'm hoping this gets settled once the tank has been running a few more months.

If I can do this again, I would get the Eheim Pro II 2028, which has gotten MUCh better reviews.

The cloudiness has settled and the tank is pristine. However, the priming button still doesn't work. I think I've isolated the cause the floating valve gets stuck in the cavity which prevents a suction from forming initially. I don't know what'll happen if I remove the float valve...maybe I'll try it next time.

Just like some of the other reviewers I have had considerable problems with leaks. The first time was after eight months of use. Eheim replaced the unit and now here I am a year later with another flood.

We purchased this the 2075 and with in 15 months it broke. It started leaking from the top. It was fantastic to come home from work to find 1/2 of a 130 gallon tank on the floor and a real scared fish. I contacted ehiem, after several emails they said it was a broken primer seal. Its suppose to have a 3 year warrenty... They would not send me one nor tell me where I could get one..... Save your money and go with another manufacture.

I have 3 big fancy goldfish in a 55g tank, which needs a lot of filtration because these fish produce a lot of waste. I was a first time buyer of an external canister filter and a first-time purchaser of an Eheim product. I had heard that older Eheim models were very reliable, but I ended up buying the Eheim Pro 3 2075 from Marine Depot because this model had a newer, sleeker design, and sounded easy to clean. I chose Eheim over other models because of Eheim's reputation. I bought the Eheim in April 2010. Several days ago, that is, a year and two months later, the filter is leaking water somewhere close to the electric cord, a complaint that other reviewers of this product have reported on Amazon and on numerous other forums. Upon finding this leak, I cleaned the filter, thoroughly checked for any cracks, plugged it back in, and it seemed to work fine. Fours hours later, I found a puddle of water by the filter yet again. I frantically shut off the filter, Googled "Eheim Pro 3 leaks" (try it yourself) and found that other people also experienced the exact same problem with this filter in the exact same spot. People also seemed to notice these leaks after one year of owning this filter, which is also my case. The Eheim Pro 3 series clearly has defects that the manufacturer needs to correct. Do not purchase filters from the Eheim Pro 3 line! When I installed this filter upon first receiving it, the filter worked beautifully and I was ecstatic with the results. Within the one year of owning it, I was able to change the filter media only 4 times with incredible ease. However, I think you only begin to see these leaks after the machine has been running for awhile. I'm disappointed with this product because I paid over $200 for the filter. But I guess as a first-time user of external canister filters, the lesson that I have learned is to not purchase an Eheim product ever again. I do not favor Eheims over other models because I lack experience in this hobby, but I do know from experience that this particular filter has failed me miserably.
