AquaClear 70 Power Filter, Fish Tank Filter for 40- to 70-Gallon Aquariums, Black

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. Jim

I LOVE my AquaClear 70 Power Filter -AquaClear Brand AquaClear Power Filters are some of the best types of filters for any tank ranging from 10 gallons to 100 gallons. Plus they are form Hagen some of the best top notch filters. AquaClear is a part of Hagen and competes with Hagens Fluval Filters which are almost the same as AquaClear Filters except that Fluval is a little more flashy and efficient. Fluval is a little better looking and efficient but if you want the same results as Fluval with a lower price tag get an AquaClear Power Filter. AquaClear has also been around for ever. Fluval power filters are just refined AquaClear Power Filters. You get the same results. I Prefer AquaClear -My Amazon Experience This is the first item I buy Through Amazon and I'm loving it. Great FAST Shipping even though I got the Free Super Savings option which can take up to 8 days for the delivery. I received this filter only four days after I ordered it. Packaging could have been better thou even thou the filter arrived un damaged. They should have added more air bags to the box to prevent my filter from moving so much. This might have been one in a thousand thou. My product was completely new as advertised and exactly as described. It was an easy ordering process too. I loved my first Amazon Experience. =Setting Filter Up Very Very easy. Instructions are clear and The filter comes with everything to set it up out of the box. It was almost as easy as plug and play things. Just make sure you have the filter case full before you plug it in or it could damage the motor or impeler or both. it is not supposed to run dry. -My Set-up and plans for Filter I currently have the AquaClear 70 Power Filter in a 20 gallon tank with 5 Mollies (One Male, 3 Female, and one fry!). Now I Know you might be thinking that this is a little too much filtering for this size tank but I am planing on getting a some more fishes (different species) and I am also going to let the mollies reproduce (This will fill up my tank). I am also going to put some aquatic pants and shrimp. If this tank starts to look to crowded in the future (because of fishes and/ plants reproducing) I am probably going to start selling some of the plants and baby fish to help out with costs and maybe get bigger and better stuff -Current tank Status With Filter So far my Tank water is super clear and my fishes are doing great. -Filter and tank Maintenance A lot cheaper to maintain than most Power Filters especially Fluvas because you don't really use cartridges and you can use virtually any kind of media aslong as it fits in the large filter basket. You don't really have to buy AquaClear replacement media. You can buy for other cheaper brands as long as it fits, you can also put custom things in it like new kitchen sponges to replace the stock filter sponge/foam. You never really need to replace the BioMax in fact I would encourage that you didn't replace the BioMax because the bacteria that it accumulates is heathy for you aquarium, you can rinse it and clean it every now and then but don't clean and or replace all the media in one day thou or else you fishes will suffer (Ammonia Spikes). Clean you BioMax every six months to a year and do the other maintenance every month or so. You do need to replace the activated carbon as instructed but you don't need to get the AquaClear Brand, you can get cheaper generic brands. You can clean ornaments and plants as you wish. Do 20% water changes every week or 25% water changes every two weeks just to help your tank health and filter.Use a gravel vacuum. (this is recommended for all tanks filtered or unfiltered) -I've also seen that it is customizable on YouTube for different things -YouTube Watch this review and comparison on youtube[...] Reviewed by Mike on his you tube channel: AquariumTech This guy does a lot ton of filter reviews and he ranks AquaClear Power Filters as being some of the best power filters out on the market for tanks 10 gallons to 100 gallons. -Suggestions Get a Mag Float Glass cleaner for when cleaning you glass(for algae or grime) or get an algae eating fish Pick your fishes carefully and make sure they get along Please have your tank go through the nitrogen cycle before you fish in your new tank set-ups Do 20% water changes every week or 25% water changes every two weeks just to help your tank health and filter. Use a gravel vacuum. (this is recommended for all tanks filtered or unfiltered) --->Do 20% water changes every week or 25% water changes every two weeks just to help your tank health and filter.

molto bellissima!!

Have only had it for a few weeks now but it works well and super easy to take apart when needed and very quiet. Hoping it’ll last a long time seeing as it’s just a bigger version of the one I had that was 10 years old give or take.

Super produit facile a installé, par contre attention vraiment gros pour un petit aquarium. Bien prévoir de la profondeur derrière l'aquarium. RAS .

had it a few months now and works perfectly for my 163L aquarium wish i could change the direction of the flow but thats just me maybe *edit* it broke on me so will try return it but worked fine until now

This is a great filter, well worth the money! I bought it for my 64 litre tank which doesn't really need a filter this big but my gold fish are very dirty, and this filter has helped keep them happy and clean. You will need an adaptor plug when buying though, which will on cost you pence!
