Aquatop Aquarium Surface Skimmer – 65 GPH Flow Rate – Efficient Waste Removal – Ideal for Tanks Up to 100 Gallons – Ideal for Freshwater & Saltwater Compatible

Anyone who has seriously been into aquarium keeping will relate to the horrors of duck weed. How it chokes out the light, overwhelms the aquarium, ruins your other floaters and gets into and onto everything. Try to net it out? Good luck soldier! This slippery, sneaky, evil floating weed skitters away and you can never get it all. I needed a way to eliminate it that did not involve tearing down every aquarium to the foundations and starting over.This little gadget does the job! Sucks in the duck weed that you missed with the net and hand picking, murders that nasty stuff. I used it to clean out two totally infested tanks last night. My big beautiful frog bit plants I would just dunk under the water and give them a shake to loosen up the attached duck weed... it would float to the top, thinking it was free at last to continue it's evil mission of world dominance... and be promptly sucked into this God send device! Now I am not going to leave it running in any of my tanks full time since they are shrimp and snail tanks where the device could end up covered in snails or sucking down some shrimp - but it was perfectly safe to use in a supervised fashion as I did.I knew though, that as evil as duck weed is, I would need to be vigilant over the coming days to ensure it was fully eradicated. This morning, a careful examination of the 2 tanks I purged last night revealed only 5 little tiny leaves of duck weed that had escaped... they were promptly snatched out and disposed of with vengeance. I will continue to watch and purge for every single tiny leaf that may have escaped. This is the first time I feel truly hopeful, the first time I feel that I may very well have just won the battle against the evil incarnate that is duck weed. If you too wish to win the fight, get this device!

Used on 20G planted freshwater aquarium. Aquarium does not have a canopy/lid so there would be dust, dirt, slick film on top. This item cleared the top of the water within 10 min and so far so good. Suction cups are strong, not sure why the negative comments about them but I am not experiencing that and is pretty hard to remove when I was changing placement location.

It is an aggressively effective skimmer. However, use extreme caution and don’t leave it on unattended. I was using it on the lowest setting and it sucked up my curious betta. I was able to save her because I caught it in time, but it tore her fins a bit and roughed her up.

I’ve had this installed on my 55 gallon for about a month now and it works so great I just ordered a second for my 36 gallon! I have two huskies so it’s inevitable that dog hair gets into the tanks so I installed this to make life easier than having to sit there with a net every time I open the lids and it does an amazing job. Highly recommend!

Good suction but fish keep getting pulled into it. Had to stop using it

this filter killed my beta. i have never EVER written a review before, but this product decapitated my fish. somehow she got sucked in through the top and was immediately decapitated by the small blades, party because of user error but also party because it’s a defective product that is DANGEROUS, it also sucked up one of my african dwarf frogs, he ended up being okay but it’s just not worth it.

Good skimmer. I use this for my 55 gallon tank and works well at removing that film at the top of the water and helps with oxygen to you fish. Recommend

I cannot believe how quick this skimmer cleaned the dust, dirt, fried chicken grease off the surface water of my aquarium. Be careful the suction cups are very strong.I thought they would be stuck there forever.
