Top Fin® Undergravel Filter
Easy to assemble, great undergravel filter.
This filter has worked great in my 8.5 gallon, and I'm planning on moving it into my new 10 gallon to help out my 10 gallon power filter and add some nice bubbles. One great thing about it is how you can choose the size you want it; I'll probably only use half in my 10 gallon tank. It is very easy and straightforward to assemble. It can be a pain to put in an established tank because you need it beneath the gravel, but it's doable. Remember that the air pump will need to be bought separately. Perfect for bettas.
P.S. I know some will be concerned to see Legos in my tank, but be assured that I did my research and made sure they were washed very well and didn't leach color before adding them to my tank. Also the air stone closest to the camera could have been pushed down further, I had just decorated and must have bumped it out of place.

Okay but could be better
Well over all the filter was cheap and on sale so I'm mad about it not doing so well. It started out working. Great [though at first I had not realized I needed to buy more than just this] but soon enough it started getting sluggish. I need to get a new airstream but the one going holding me back from doing is so it that it s so hard to use and put together. The little air tubes are amazingly hard to get through what they need to get through. I know it needs to be air tight but I can't help but wish it were easier. The filter does it's job though so that's a plus all though it got sluggish within only a few days.

Not really that great an option
This is a very dated way to filter a fish tank. It does keep the gravel a little cleaner but can build up mold if not removed and cleaned well every few months. A good vacuum is a must with or without a Undergravel filter so why bother. Tanks that you that have them have very clear water which is a plus, however many people who buy these have Water Parameter issues. Just read the thousands of nightmare cases out there. I completely understand how they work and have used them with great success but they are "Cheap" and "dated" an there are much better options for not much more $$. If you have a planted tank stay clear of these because the become clogged easily. On the flip side if properly maintained the make the tank "chemicaly" clean. This is no true replacement for a living tank, or a power filter like the ones we have today.
Pros: Easy to install, and well made
Cons: Hard to clean for some.
I refuse to say that they dont work, but I also refuse to say that they are the greatest. For beinners I would suggest Buying a hang on, or if you really want a great setup get a canister filter. Save up, buy the best you can get for the size tank that you have. You take good care of your water and your fish will always be happy. Fish owners shouldn't worry about the fish as long as they are fed and the water is perfect.

(Brings back good old memories.) I bought this Undergravel Filter today. Its running good. I am using it on my 10 gallon aquarium. Easy set-up. The only downwall is the tubes are tall as a ten gallon aquarium (height wise)... so I trimmed about 1 inch of the bottom tube and now its better.
