Love this filter! It holds a lot of media, easy to clean and love the adjustable flow.! I will be buying another one for my other tank. Highly recommended.
Had the old one aqua clear 15 years ago and it was great. I like the changes they made and my lid doesn’t rattle. KG tropics it a great online store.
This is a great product. My aquarium water is crystal clear. My fish is happy! This product is worth every penny spent. I would recommend it to anyone Thanks John and Lisa!
Great addition very sleek design fast shipping and great service!
I like this filter is quiet and it been doing good for me while my cycle
All the changes, made it a perfect HOB. Filter. So far it’s working great.
I have this in my recovery-holding 55-gallon aquarium. It was filtered using two penguin emperors, but this HOB is far superior, far more powerful, and far easier to use. I just love it. One other great thing about this product is that you can change out whatever you want to circulate in your tank. It’s just an astounding filter. I love it very much. Highly recommended.
I have a lot of Fluval filters and I absolutely love the new one. I want to replace all of my non Fulval filters with this one (maybe different sizes). I have 11 tanks to work on so it will take me a while to get everything replaced but it is totally worth it. I get asked what a good filter for a 10 gallon tanks is and never could give an answer before but now I can highly recommend this one and I am glad it came along.
I received the new Fluval AquaClear AC 20 for my 10 gal tank. Thank you John and Lisa for stocking these! A huge perk for me was the motor on the outside (have less to clean and more room inside) especially for a nano tank. The lowest flow setting is perfect for a 10 gal betta tank. The quality sponge fits nicely inside the box along with the other media as well. The only thing I would have wanted changed would be using black rather than clear for the intake tube. But that's being super picky, a personal choice and not a deal breaker by any means. Sonny (my outspoken and opinionated betta) gives it a fin's up! Thanks again for choosing to sell another quality filter! And to add...the customer service was again top notch. Your diligence and dedication to your customers shows!
I love this filter! I bought the one that goes up to 30 gallons and is 150 gph, my 10 gallon tank is not over filtered and can slow it down if I need to. I used Seachem matrix and filter floss in the back,,but you can put what you feel is best in it. Really awesome HOB, and if the electricity goes out it starts back up and I can’t even hear it running . It’s nearly silent . You won’t be sorry you bought this. I have the smallest size upstairs on my shrimp tank and it’s perfect . The sponge filter cover protects baby fry or even the thinnest baby shrimp from being sucked up .
Quality product. Excellent performance.
Works great in my 20 gallon long. Easy to set up and the Iowa darters had fun playing in the flow.
Great filter!
Everything I purchased is such a step up from what I had! I’m so happy and the fish are too! Thank you!
Nice and quiet for a hob filter. I have tested pulling it apart for maintenance and is by far the most convenient hob filter I have.
HI I JUST WANT TO THANK YOU FOR I HAVE HAD MY BETTA 2 YEARS AND HE IS DOING WELL AND MY SNAIL ARE DOING GOOD TO I JUST LOVE WATCHING THEM
This filter slipped right in place. Was so easy to prime and start. Very happy with it and KGTropicals
Fiter quit. This one is a good one!
works as expected thank you Brian
Filter is working awesome and customer service is great I still stand by my recondition to use Kgtropicals for all fish keeping needs.
Arrived quickly. Works great, my fish are happy
This is a great filter!
I looked at several options for new filters for my 10 to 20 gallon tanks, and found the Fluval AC series provides better media customization while protecting fry and shrimp. I modified the media to include adding a thin polishing pad above the sponge, mixing Fluval BioMax, seeded Seachem Matrix, and Biohome for my bio media, and adding Nano chemi-pure blue and Fluval Zeo-Carb for my chemical crew. My tank hasn't been this crystal clear with medium-level stocking for months! Although Fluval indicates this filter is good for tanks 10-30 gallons, I find this filter absolutely perfect for my 10 gallon tank. I highly recommend not going with a smaller filter for a 10 gallon tank.
I love this filter! It’s the perfect size for my 30 gallon tank, runs super quiet and holds a lot of media. Very easy to clean-highly recommend it. Fast shipping too!
1st time ordering feom KG Tropical and everything was great. Couldn't be happier with the product.
Right now I cannot give a view because it is a Christmas present for my husband. I will definitely give one after Christmas. Enjoy your Holiday
Great little filter
I have one already, this one will replace a Top Fin filter as soon as I run out of their filter cartridges, and put on my Aquaclear 20 with the skimmer.
This is my 3rd filter of this type that I have purchased after watching your reviews and I absolutely love it. Best filter for my community tanks with fish, shrimp and snails. The only thing I would change is the intake sponge, with it having openings on both ends my shrimp still find a way in. Luckily I have intake sponges that I purchased for another filter and they fit perfectly.
It came with the impeller stuck, and it kept sticking off and on. I got a tidal 35 to replace it and haven’t looked back. Im keeping it just in case the replacement part works and i need another in case of emergency.
It works great and it was easy to install. Love it.
I’m so far very happy. It’s not noisey not too large and moves water nicely with great filter mediums This is the second filter you have recommended that I’ve bought and I’m happy! Thanks!
Just put it on my shrimp / snail ten gallon tank. I'll know more down the road, right now I have the charcoal filter and pillow stuffing, because I didn't read directions or look at the pictures on the box. I want to use as many charcoal/carbon filters to keep the odor down.
Great deal and perfect for my 10 gallon tank.
Seems do be doing a great job. Used seachem purigen instead of the included activated carbon and my tannins have cleared up greatly
Super quiet and does a great job with the clarity of the water
Very good choice if you take this item really I like it thanks
I have a Tidal 55 and this AC 70. The AC70 def does a better job at filtering. The water goes thru the filter media. On the Tidal, it just goes to the overflow and doesn't get filtered correctly. Love the AC70.
I absolutely love these hang on back filters 💗 works great
