Marine Color Aquarium Surface Protein Skimmer 5W JY03 Aquarium Oil Film Processor JY-03 Oil Removal Filter Fish Tank Filter

I use this as a surface skimmer for my 75-gallon tank. I put foam matrix (bio bed filter) in the undercompartment, but I left a hole in the middle, so the water travels to the impeller unheeded. I also closed the lower door completely, so all the suction comes from the surface water.Every day, I do two a two-bucket water change instead of a weekly change. The fish love the consistency of the water quality. During these changes, I rinse out floss that sits in the upper compartment. To keep the floss there, I cut a small piece of plastic canvas that sits in the bottom of the top portion.(Plastic canvas is an aquarist's friend.)The constant cleaning it does to the surface of the tank has greatly improved how my fish act. I think it removes the proteins and scum from high-protein and high-fat foods I feed every few days. And a clean surface is fantastic for gas exchange.The crazy thing is that this skimmer works for an entire 75-gallon tank. That is a surface of six square feet. I cannot imagine how this little dynamo would do in a nano tank. The fish would surely feel like they were in a blender!Anyway, it's been chugging along for four years, and it has just been a great addition to the tank. I keep it by the fluidized bed, so the other side of the tank has low current. Fish like a choice.Two soggy thumbs up.

Going on 1 year and still doing fine. This has been a great little skimmer for my 20 long Pea Puffer tank. Really get the fine debris cleared from the surface. I'm amazed at how well this skimmer works. Great value for the money spent!

The skimmer did a wonderful job of removing the floating oils, etc in my aquarium. I cannot fault it there. The (non)- included instructions were less than helpful, but hey, if you bought this, you are likely already familiar with how things-aquia generally work. I filled the little chamber with some filter fluff, and set it to work. And it did work.... until... it stopped. The impeller seemed stuck, so I took it out of the tank, tapped it a bit, and the impeller started. OK Cool... until a week later when it did it again. So again, I removed it from the tank, fiddled a bit with the impeller with the help of a cable tie. And again, it started... and I discovered, if I ran it with a full stream of bubbles by adjusting the odd thing with the "sponge" in it, it seemed to perk along happily... for about another week. Today, it stopped again... Now, I don't mind occasional tank maintenance, but this is getting ridiculous. On the plus side, I am still cycling the tank, so I have no fish in it, but there is something obviously wrong with either my particular unit, or the design in general. As I said, it DOES work great. But only when it's working.

Just the right filter for aquariums that needs surface filtering but with little surface agitation. For all aquariums that have duckweed this is a life saver.It skims the surface perfectly then it takes that oily surface water, filters it and returns it back into the aquarium with a mix of fresh air.It's like having a waterfall without having a waterfall!With the adjustable air flow, you can aerate your aquarium to get the right amount of air bubbles.Don't add too much custom filter media in it or the floating weir won't move up or down like it's supposed to. It works fine with the filter pad that comes with it.The flow is stronger than expected. I have 1 on my 55 gallon blowing across the rear and none of the duckweed gets disturbed. Great for African Butterfly fish😁

I just got it in yesterday (3.11.24). Packing looks kinda generic(no picture, brand or model number. Everything seems to be in the box, being there was no parts list or instructions. But anywho, so far so good. Installed it in my 20 gallon nano saltwater tank. It did clear up the build up on the suface. I don't feel or see any difference in flow regardless which way I turn the dial. We'll see how long it'll last. I'll do an update at the end of the month. 🤞4.22.24 update. It was working great, now it's not skimming the suface no more. It is just moving the water like a powerhead. I wish i can return it but that window closed on 4.10.24 Do not waste your time and money on this item.
