Fluidized Moving Bed Filter Bubble Bio Media Reactor for Aquarium Fish Tank with Air Stone and Sponge Filter

better than the ziss in my opinion and i have one i will order more for the rest of my tanks

The media could not be loaded. Using this as a calcium reactor in my 10 gallon reef aquarium. Probably only helps a little in that regard as I still have to dose 2 ml per week of Seachems Complete Calcium to keep my levels at 400 and this is with a 10% water change per week with Ocean Reef Crystals. Still the calcium media also provides surface area for nitrifying bacteria so has the added benefit of helping clean the water and all my water parameters were acceptable with ammonia and nitrates registering just above zero with a Fluval AC50. Happy to have it in the aquarium.

The media could not be loaded. I installed it & i have a good air pump, the bio ‘s did not move a lot the next day i removed some bio filtration & removed the sponge filter that made the bio tumble a lot better.When i removed the sponge after 12 hour use there wasnt any debris on the sponge.

Bought this over a year ago and still has great suction to the glass and works great for my 6 gallon Betta tank. It doesn't move water too much at the top where my Betta is still comfortable going to the top. Highly recommend!

Update 2 - Eureka, I found them... Suction cups that is. I bought a package after comparing diameters. The cups list below fit. And they are multipurpose for other aquarium things including attaching plants to the glass. Search for "B082CXMPSJ" on Amazon. Item is SCZ20 at Pawfly. Tag has X002ELTNLB, 20 pack suction cups UL411"Pawfly 20 Pack Suction Cups with 40 Pieces Adjustable Zip Ties for Aquarium Fish Tank Binding Moss Shrimp Dodging Nest"Update - Quavee now has a 4 pack of spare airstones!Reading some of the reviews had me scratching my head. I have LH-300's and LH-600's in tanks upstairs. They are not 'cheap' plastic. They hang about as well as expected for anything with suction cups in an aquarium. They have a good load of media.They are a biological filter. They require time to 'charge' with bacteria. Also initially, the media has to become saturated, so it can take up to 3-4 days before the media will fully start moving. I would not consider them 'seasoned' in less than 2-3 weeks as would any sponge filter. The advantage is what a moving media bed filter has in a handy package.The only drawback is the air stone. As with any air stones, it becomes clogged with minerals reducing its effectiveness. You have to soak the stone in vinegar to remove calcification to get it working again. But, you should not take the stone out and leave the media sitting for that cleaning time as the bacteria will start dying. So currently, you should be an extra one so that you have a spare airstone (they are a custom configuration.) I and other have requested Qanvee sell spare stones. Waiting.There are some others here that appear to be the same model or clones offered by others. I had one tell me that they don't have an airstone when one is clearly visible in their pictures. I have not had such stupid answers from Qanvee when I asked them questions.Update - Qanvee now sells a 4 pack of airstones!!! To recycle, you soak the used ones it in vinegar, then water, it must dry completely to restore the flow. Sort of hints that it may be biological buildup instead of calcification in the airstone. I may try the hint of drilling a whole in one of my stones (I have .75 mm diamond bits). Just letting the stone to sit and dry out helps immensely.

The filter was not seal wrapped in anything, two of the suction cups were missing. Box was not taped shut.

The media could not be loaded. Works good can put any media filter in it since I got a big media filter on back now I put the stuff in it that it came with keeps tank clean I use it as a small 2nd filter in tank

The media could not be loaded. It doesn’t come with instructions but it was so simple to use, a fish could set it up. People were complaining about the media in it and the lack thereof but I found it to have plenty. Even without adding my own, it was 3/4 full. It did look like there was less when it was actually in the tank, bubbling, but you have to remember there has to be some movement, that’s the purpose of the media in it. I did add some of my own for my own purposes, which doesn’t float but they’re rocks so that’s normal. It’s only been in the tank for half an hour but so far I like it. Compared to other suction cups too, it holds really well. Every other one falls off and I actually had to force this off so I could reposition it. Someone asked if you can place it horizontal and I want to make clear, you cannot. I tried it for kicks and it wasn’t bubbling. But maybe it was just me, so try it out. It’s a little larger than a normal Poland Springs water bottle for reference. Not the prettiest of things but what internal/sponge filter is? You can always block it with a plant or an ornament. It won’t do a whole heck of a lot in my 75 gallon but it’s a back up for my Fx6 and extra water movement for my slightly overstocked tank. As long as it continues to do its job, I’ll be buying one for my next tank!Update 6/2021I’ve had this filter for over a year and after about 6mo of use, it no longer stuck to the walls of the tank no matter how much I wiped clean the suction cups or pushed it hard against the wall. A year later and I’m taking the 2 I have in the tank out slowly because they annoy me that much.
