The whisper filter seems to work very well. I have no problems with the cleanliness of the tank or the health of the fish.

I bought these for my plecos, but my snails also love them! It's enjoyable to watch them snack on the wafers.

I have used this in my 30 gallon tank. It greatly reduces the time I spend cleaning my tank.

This is the only food my fish have every eaten....some of the fish have been in my home for 3 years, so it's obviously a very good, nutrional food.

My dog used this food in the past. It was well-tolerated.
