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

Good filter and does what it is intended to do. I always use a larger filter than what is recommended for the size of my tank. As a starter tank for my daughter we got her a 20 gal tank package that came with a cartridge type HOB filter. The cartridge type filter becomes overwhelmed very quickly and will not last the recommended 30 days. After about two weeks with an under populated tank we noticed the water clarity going down. After a few hours of running this filter before a water change the water quality improved significantly. Only complaint with this filer is that it came very scuffed up on the housing of the filter and extremely dirty. The lid is warped and doesn't fit right otherwise it would be a 4 star. Filter is functional and fairly quiet and has a water flow adjustment. It does not come with the water intake pre-filter as the images suggest. I did not find the motor to be noisy as other posts suggested or at least not noisy enough to complain about and quieter than the last filter which we purchased from Petsmart. UPDATE!!!! - 6/14/2025 - as mentioned above the lid on my product was warped and does not fit right. After about 1 week of running this AC70 filter, water was pooling around the tank. The filter was leaking water where the motor connects to the housing. I tried to tighten it and reseat the motor, no luck and the leak continues. In the pictures you can see where the minerals are drying where the water drips from. Amazon is replacing this product so I hope the next product functions correctly. By the way the majority of the images for this product are of the Fluval AC70 and not of this product which is made by Fluval but of cheaper quality. If the new one has problems Ill return it as well and spend more for the actual Fluval. UPDATE PART 2 -6/17/2025 - New (replacement) product arrived from Amazon and it was in much better condition than the previous product. It was not all dirty and the filter housing was glossy and not scratched like it had been used. I promptly changed out the old filter for the new one and overnight there does not appear to be any leaking. In the removeable motor housing there is an "O" ring that helps create a water tight seal. It is possible that on the old filter that it too could have been damaged or old. Not sure if this was a quality control issue or if these were from different manufacturing sites because even the durability of the plastic housing and lid seemed better. Initially I gave this product 3 stars due to the damage to a new product. Since the product is now functional and looks like a new product and does exactly what it is supposed to do I upped to 5 stars. On a side note I would highly recommend the the intake filter that does not come with this product but is a very cheap item. I thought it was just for larger particulate matter but when I was replacing the filter I removed the intake filter to use it again. I brushed off the larger visible particles and decided to give it a quick rinse. When I rinsed it I notice that it collected a lot of fine particulate matter and had to rinse it about 3-4 times before it ran clean. Also after about a week of the old filter running the white foam filter showed almost not dirt or discoloration. When I rinsed that filter it showed no dirty run off. Conclusion - intake pre-filter is a good investment!

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.
