    Do it!! Every aquarist should have a few!
  

*by Z***H on Reviewed in the United States on January 19, 2019*

No complaints at all! I can't believe you get 2 complete filters for what 1 sponge prefilter often costs. They work great. In fact I have one in a 10gal with some shrimp guppies and angels, and one in a FIFTY FIVE gal with angels acera gourami a loach and some danio. It is keeping up so far. The air pumps are tailored to each tank- so small cheap Wal-Mart pump on the 10 and decent size dual outlet on the 55 only using one outlet to run the filter. Ultimately on tanks over 10-20 gal these probably make a better supplemental filter but using one on my 55 while I work on my canister filter is proof of concept. They seem to cycle very quickly and be fairly responsive to bioload demands. Grow out tanks, shrimp tanks, tanks with small fish or betta these are ideal. They are also extremely simple AND allow you to have another point of aeration and circulation. I put the pickups in areas where water wouldn't always be moving super well (behind big decor, corners) and they help keep it all clean. Shrimp love to pick off em, my botia likes to hide under/behind them.The outlet is adjustable in height. It fits in my 10 and the outlet gets pretty tall probably about 18 inches total.Everyone should have one running. If you get Ich, have fry, any reason you need another tank like, *now* these are great. Put water in. Warm it. Drop in an airline and sponge and it's ready to keep your fish safe.

    Quiet, reliable, powerful, safe, cant get much better
  

*by J***G on Reviewed in the United States on December 8, 2018*

I bought 2 of these and 2 new aquariums for invertebrates and absolutely love them.  I have not had an aquarium for years and maintaining the filter was my biggest concern until I learned about sponge filters.  These are perfect for breeding tanks and nano species.  beautifully light and still feel tough, not to mention easy to clean when you do a water change, simply squeeze it out into the old water and replace...literally takes 15 seconds and the sponges have shown no sign of decay or breakdown after 6 weeks of shrimp and crayfish picking at them.  Will buy again, awesome customer service from the company as well.  Buy with confidence

    You do actually get two
  

*by R***L on Reviewed in the United States on March 7, 2019*

I have these in a 30 gallon long/breeder (36" long 18" high). They cleared out the dust from the sand really well. I have both hooked up to the same normal air pump, the further one doesnt get as much air as the closer but it still pumps. I'm not sure I'd trust one of these in anything larger than a 20 gallon when used by itself. The back of the packaging has some spelling errors haha but they're cheap and work so can't complain.
