great, but if you don't have a charcoal filter.

looks great but unless you have a charcoal filter there really is no need for replacement sponges if they are. Just wash them. I was new when I bought them and didn't understand!

Pros
  • handy item

Amazing value. These filters can actually be washed and used.

Amazing price. These filters are indeed washable and reusable. Eventually it gets to the point where it gets too crowded and the material won't come out even with very hot water. then it must be replaced. It's cheap enough and better for the fish.

Pros
  • This is amazing
Cons
  • A few little things

Very useful in my 5 gallon tank.

I bought this for my 5 gallon beta tank to replace an inline filter that wasn't working. It's quiet, durable and efficient. I'm not giving it five stars because I prefer not to buy pre-made filters, but if that suits you then I highly recommend it. Bonus: I let the water get too low and the unit ran about halfway in the water for a full day. No problem, I filled the tank and it works just as well as before!
