TC900/2000 Submersible Aquarium Internal Filter, Adjustable Fish Tank Filter with Water Pump for Fish Tank (for 5-30 Gal Aquarium)

So I feel like i've ran every filter imaginable in the past 30+ years for SW and FW. For SW this could be used in a pinch to maybe run some media or whatnot but this is a FW filter. Its pretty small but the output isn't bad. Pro's: 1)Quiet which is why i tried this vs HOB. 2)Easy to Clean. The media boxes pop right off which makes it easy to clean. 3)Plenty of sponge filters. The sponge filters are great, ranging from largest to smallest correctly. 4)plenty of room in compartments, just in case you want to remove a sponge and add in carbon, ceramic....etc. 5) Water can only flow from bottom forcing all water through each filter layer. This is a great feature vs many of the others out there. Sure it will clog easier, but you know when your filter needs to be cleaned and you know your filtering through every layer.Cons: 1)Suction cups. I'm expecting this dude to eventually fall and turn my tank into a sandstorm, this will happen unless you place some failsafe measures. Tape the cord to the back of the tank, or tie it up...etc. 2)Its small so will need alot of cleaning which isn't a huge ordeal, just saying. 3) Pump does seem to make noise if it gets clogged at all.Overall so far its great, replaced some HOB filters and the noise and cleanliness looks great. It will be interesting to see how it holds up after time, but they are pretty dang cheap.

Order came fast, instructions say there should be bubbles but im not seeing the bubbles like the diagram shows. It puts out great pressure just not putting out air bubbles like i thiught it would. In the photo the ofilter putting out the bubbbles is the UV filter

If you are looking at this product, my suggestion is buy it, it is completely worth the money, currently using it on a 10 gallon shrimp tank, the filter housing is cut into three compartments, which one of the compartments has to be removed to fit standing straight up in aquarium like i have it in the picture. Which to me is completely fine. I removed one of the filter medias, and combined the other two medias in one compartment, the fine and the medium sponges, and in the other compartment i added a bag of carbon. Works awesome!

Replaced a topin charcoal filter. This is working well. Clean it usually 1x per week. Pulls apart and simply rinse the spongesedit: after many months it's still doing great. Haven't had to buy anything and am saving 20 bucks a month because I used to buy charcoal...what a mistake that was. Now I know. My fish and snails are happy, the tank is clear and maintenance is easy. Very happy16 months later and it's still going strong. Of note is, sometimes if you put the top blue filter in standing up instead of sideways the filter will not work properly and might make you think it isn't working. Just make sure that top blue filter is sideways to leave space between the fan cage and the filter.

I purchased this for use in my 20 high tank so I could set it up close to a wall. After a couple of weeks, it is doing a good job of keeping the water clear. I saw other comments about how strong the flow is coming out of this filter. It would be nice if there was an adjustment for that. As a workaround, I have found that if you use the directional spout to point up and slightly to the side of the aquarium, it works out pretty well. My little black moor is able to just hang out without swimming for his life now, but there is still water movement and aeration happening. I hope this is helpful for someone.For cleaning, the sponges are easy enough to clean, but mine was a little but tricky to pop apart without flinging part of the filter across the room. I'll be more careful next time.
