a lot of problems

I have had a lot of different filters and brands throughout all my tanks but this one by far is the most frustrating. i have it in my 40 gallon breeder cichlid tank

I have had a lot of different filters and brands throughout all my tanks but this one by far is the most frustrating. i have it in my 40 gallon breeder cichlid tank to add a second filtration. it hasn’t even been in a week and it constantly dies and stops working. my bf has to tweak with it a bunch or keep it unplugged for awhile. it makes a supple loud noise like it’s about to poop out.

Quite and Efficient

Our Aqueon canister stopped filtering after 3 months and it was difficult to clean without getting water everywhere so we decided to go back to a hangover filter

Our Aqueon canister stopped filtering after 3 months and it was difficult to clean without getting water everywhere so we decided to go back to a hangover filter. So far, I’m very pleased and my fish seem happy. Their water is clear and the motor is very quiet. Time will tell but so far, so very good.

The best hang on back filter on the market.

Don't look any further for a hang on back filter. I have tried almost every brand including the overhyped Tidal. The new redesigned AquaClear filters are perfect

Don't look any further for a hang on back filter. I have tried almost every brand including the overhyped Tidal. The new redesigned AquaClear filters are perfect in every way. Plenty of room for media, quality construction, a design that doesn't easily bypass the filter, adjustable flow that recirculates the water internally, a nice size 30 ppi sponge that will keep your water nice a clear. There is nothing to not like here.

New Design New Look

Like the new sponge filter I can put on the intake tube preventing snails and debris from entering filtering mechanism. Keeps the motor mechanism nice and quiet

Like the new sponge filter I can put on the intake tube preventing snails and debris from entering filtering mechanism. Keeps the motor mechanism nice and quiet. New internal rack situates media differently. Looks good, not sure if it makes a difference. Cost has gone up. Used to be $40 years ago, now in $70 range.

AMAZING!!!!

I absolutely love this filter, it’s so well made, and it beats the marineland by a long shot. Quiet and powerful, with a very smart design.

The motor for the filter assembly was in crooked and began leaking as soon as I filled the filter with water. Upon further inspection I found it broken. The motor costs $32 to replace.
