API 21 First Impressions

I totally recommend this.

Thanks to the Amazon reviewer who mentioned this! I swim 5x week and usually my suits last about 2 months. These filters get the job done, but do plug up quickly when my water is that gross. I used to use AmQuel years ago and then spent years out of the aquarium hobby. The filters are expensive to replace and only so-so quality. Sure enough they are back to their healthy coloration and didn't end up dying on me. However if you want a stress coat, this is perfect.

API 21 Final Thoughts

5 ga beta fish bowl.

This water conditioner is a life saver! I haven't tried looking for alternative brands. I don't have to work a hard as I did before just to clean my tank. I bought this airline tubing to work with my air pump. I will purchase this again when needed. The auction begins with just a few squeezes even my young nephew could do it. I wish the length of the section that is in the tank was about a foot longer.
