    We’ve used this filter four years, just replaced with identical unit because of wear and tear (Cleaning). No issues at all, great brand of products.

    I have a 10 gallon tank that some may say is a little over crowded and my 10 gallon filter could not seem to clear the murky water up. This filter worked great and cleared the water up. Within a day it looked way better and within 2 days the water was cleared up. Very easy to put together and easy to clean. Also it’s pretty quiet doesn’t really make any noise. Adjusting water flow is easy as well.

    Folks, I’ve owned most of the popular filter brands including Marineland Bio-wheel and Magnum canister filters. The Marineland would grow very noisy and the Bio wheels would not function properly over time while the Magnum was a hassle to clean as they would leak every time upon opening and was hard to line up the O-ring when re-assembling the unit. But after 30 years in the business, I’ve settled for the cost-effective, easy to setup, reliable, AquaClear HOB filter. I now run two, AquaClear-70’s on my 60 high, Cichlid tank which allows me to run one while I clean the other, for continuous filtration. I also run one each on two, separate holding tanks outside. They are easy to setup, easy to clean, quiet and very reliable. Amazon also sells replacement impellers and intake tubes, if needed. Pairing them up with the after-market, media basket and you’ve got an extremely efficient filter system where you can also mix-n-match you filter media. If you’re looking for a filter that’s user-friendly, quiet and works like a champ, look no further than the AquaClear-70! Simple, silent, strong, reliable & extremely effective. What more can you ask for?
    June, 2017 UPDATE – BEWARE, THIS FILTER WILL OVERFLOW!! In the 3-months I’ve owned my AQ-70’s, they have overflowed twice! Both times we were fortunate to be home and therefore, the filter did not have a chance to drain my 55-gallon aquarium down to the lowest point of the intake tube, onto my living room floor (did anyone else have this issue??). Upon close examination, both incidents involved the filters with the after-market Media Baskets installed. Apparently, the Media Basket is so effective at minimizing by-pass water that it actually works against the filter. As the filter sponge inside the Media Basket slowly becomes clogged over time, water flow becomes increasingly restricted causing the water-level to rise until it eventually overflows. Unlike canister filters, dirty filter media in the AQ-70 does not reduce/restrict the output of the filter motor which keeps pumping at 100% capacity. This combined with the super-efficient after-market Media Basket appears to be the problem. The stock media basket appears to have more by-pass water flow which is returned to the tank via the spillway (preventing overflow). So the stock basket does not appear to have this overflow issue (or is much more forgiving) and I have since restored my AQ-70’s back to stock configuration (we’ll see). Bottom Line, if you choose to run the (expensive) after-market Media Basket, you will need to “religiously” clean it 3-weeks or monthly, depending on how much fish you have. Oh, I still love this filter’s simplicity and effectiveness, but now monitor it’s dirtiness and subsequent water level much more closely than any filter I’ve used before.
    FLUVAL C-SERIES vs. AQUACLEAR – I’ve done some research on the Fluval C-Series HOB’s and found that the Fluval is quite similar in design to the Aquaclear. The main differences on the Fluval are the extendable intake tube and dedicated filter media compartments. But the feature that really caught my eye on the Fluval was the media dirtiness indicator which is a plastic red knob that becomes exposed as the media gets dirty and the water level in the filter rises (pushing up and exposing the red indicator). This to me would help prevent an overflow (if a potential overflow condition even exists at all on the Fluvals?). CONCLUSION – IMHO, if you choose to run Aquaclear HOB’s, don’t be lazy and “forget” to clean them or you could possibly be setting yourself up for an overflow condition, especially if you run the after-market media basket.

    UPDATE: 10/15/14

    I have just purchased my first Aquaclear HOB filter in more than three years. I presently own an AC 110, AC 70, AC 50 and 4 AC 20s. These are great filters because of their clever design and tremendous flexibility.

    I am presently using a pair of Aquaclear 20 filters for polishing the water in my planted aquaria. The filters are equipped with a mechanical filter pad and a micron filter pad, the later of which is used to remove the finer particles from the water column in these tanks.

    I like using the AC 20s as part time maintenance filters because they are small, very easy to clean, and do an excellent job of filtering my planted aquaria.

    I use an AC 50 in combination with an Eheim 2211 and Cobalt Aquatics DUO 500 in a Mr. Aqua 17.1 gallon aquarium. The DUO 500 is an internal filter, however, its primary function is as an LED UV clarifier.

    I downsized some of my tanks, so the AC 110 and AC 70 are no longer in use. However
    I keep them around as spares, since you never know when you will need an extra filter.

    One of the best aspects of the Aquaclear line of HOB filters is that the motors in the AC 20, AC 30, AC 50 and AC 70 are the same. The only difference is that the impeller fan is slightly larger on each subsequent model of these filters.

    The fan can be easily removed, and either a larger or smaller fan (depending on the AC HOB filter that you are using) can be added to meet the demands of the particular aquarium you are using.

    This is why AC filters are so popular; their tremendous flexibility.

    For example, suppose that you have a 20 gallon aquarium and are using an AC 20 that doesn’t quite get the job done. You can purchase an impeller assembly for an AC 50
    and then use it to replace the AC 20 impeller fan, which will give you twice the circulation that you had with the AC 20 impeller fan.

    As another illustration using the inverse of this situation, suppose you are using an AC 70 in a 30 gallon aquarium and find that even on its lowest setting it is
    still causing too much turbulence for your fishes.

    You can replace the AC 70 impeller fan with an AC 50 impeller fan. This will still give you the filtering capacity of the AC 70, however, without the turbulence that the AC 70 impeller caused.

    Earlier…

    My recent purchase of an Aquaclear 70 HOB (hang on back of tank filter) filter ill make this my 8Th Aquaclear. I have five Aquaclear 20’s – three on guppy tanks, and two kept as spares in the event of a breakdown. However, in over a year of constant service, I have yet to have an Aquaclear HOB filter’s electric motor burn out.

    Moreover, one must take care to turn these filters off when you are using a sand substrate which is being stirred up in the tank, since the sand can get into the motor and cause it to run roughly, or seize up.

    Even if this happens, all it usually takes to get these motors running again is to remove them from the filter housing, remove the impeller from the housing on the motor and clean the unit with water and a q-tip.

    Once you have done so, the motor will usually begin to run properly again.

    However, once sand gets sucked into these motors, it mars the finish of the impeller, which can cause it to make noise.

    I also own an Aquaclear 50 which I now keep on my 10 gallon tank, and an Aquaclear 110 which I use to filter a heavily planted 20 long tank with about 16 fish.

    So the extra filtering capability of the Aquaclear 110 is nice to have.

    As for the Aquaclear 70, this will be replacing the Aquaclear 50 which I used to filter my 37 gallon tank, and have now moved to my 10 gallon.

    The Aquaclear 70 will be used in conjunction with a Fluval 305 canister filter for redundant filtration.

    The Fluval 305, like the Aquaclear, is another Hagen product. It seems like virtually every product that is sold for the aquarist is manufactured by a subsidiary of Hagen’s.

    The 305 is also a very cleverly designed filter, which works quite well, and is very easy to maintain, thanks to Fluval’s patented Aquastop feature; the Aquastop fitting allows you to disconnect the 305 from its tubing without losing suction, so that you don’t have to reprime the unit once you’ve dumped the water from its container during a filter cleaning.

    All you do is reconnect the Aquastop fitting to the top of the 305’s canister, and then open the flow valve until the 305 fills with water.

    You must open the valve partially to avoid creating a tremendous amount of turbulance in your aquarium, since if you open it all the way while filling the 305, the air bubbles will race out of the 305’s exhaust tube disturbing your fish.

    As for the controvery between which canister is best, many people who consider the purchase of a Fluval also consider buying an Eheim, and there are those who own both. The Eheim – Fluval debate reminds this author of the Chevy-Ford controversy, regarding the merits of each.

    Moreover, I have owned both and find that Fluval and Eheim both make excellent canister filters. However, the Fluval’s internal setup is much easier to use, given the trays Fluval includes to add filter media to, while the Eheim Classic series (I’m not certain if the other Eheim filters are the same way) just stack the media atop one another, making for a more complex arrangement, since the Eheim’s filter media is in not in a tray.

    Both filters are well made and reliable. However, one must take care to re-lubricate the Fluval’s o-ring after each cleaning to ensure that it does not dry out, since this will prevent the unit from leaking onto your floor. And careful removal of the impeller housing will ensure that the impeller that does not get damaged.

    After more than a year with the Aquaclear series of filters, as well as the several months with a Fluval 305, I must say that I am very pleased with these units. They are cleverly designed, well constructed, and should last for years provided that they are properly maintained.

    Because I have a betta in a 29g community tank, having a filter with adjustable flow was more important to me than a self priming filter. The start up was easier than I expected. Once I filled the filter box with tank water & plugged it in, it fired up immediately & started running like a champ. And it’s SO quiet!! I thought my tank water was clear, until I saw what crystal clear water really looks like a few hours after plugging it in. The included media is great, especially the biomax and there’s room to customize everything a bit.
    The filter box also fit easily into the original aquarium hood opening which was a big bonus. AquaClear designed this filter so well that it’s big enough for all the media but still low profile. Such a great filter from a reliable brand!
