Aquapapa Bio Sponge Filter for Betta Fry Aquarium Fish Tank Up to 60 Gal ea. 3-Pack (L)

These sponge filters are great for 20gal and up. Great Value, 2nd time I’ve ordered

Good price for 3 units. It takes longer than other sponges I have to get colonized by bacteria, so it will take longer to acclimate your tank.

no outflow tubes??

All three work perfectly, and set up in seconds!

As advertised.

I used this in my axolotl tank, and after about 12 hour using it, I already saw the water getting mercy. After about three days, I couldnt even see through the tank because the filter was now trapping and spitting out filth and leftover poop. Terrible product!

One of the simplest, economical, and most effective filtration methods for keeping fish alive, with regular water changes with clean water of course. For those that are new to the hobby of fish keeping please look up the ammonia - nitrite - nitrate cycle. This filter only works after the bacteria’s form huge colonies on the sponge. It’s the bacteria that consume the fish waste and convert it into non-deadly (in small amounts) nitrate that you remove with water changes. Until then, it’s just a sponge. If you remove your old filter and replace with this one out of the box you’re killing your fish. Not the filter, YOU! Run this filter along side your old filter for a minimum of two weeks, MINIMUM, before removing the old filter. Consider adding Cycle (Fluval) or Stability (Seachem) to boost the bacterial growth. Clear water is wonderful, but what kills your fish is invisible to humans… Ammonia + Nitrite + Cycled Sponge Filter = Nitrate. Nitrate + Human + Water Changes = Happy Fish. This filter works perfectly once established. In fact, I always have an extra one cycling just in case I need it. Never know when a fish is going to get sick and need a quick set-up hospital tank. If you’re thinking about aquariums, this is the foundational aquarium filer everybody uses. Because it’s cheap and it works!

Love it

These things float

They seem like a good value and are definitely about what I expected. I havent figured out how to use them with my power heads yet, as the diameter of the sponge is so large the power head sits too far from the glass to mount it. Im probably going to try a different diameter if I use it with power heads in my 75 gallon, but works great in my 29. Takes up some space though.
