Review on Pawfly Release Airstones Aquarium Hydroponics by Brenda Quiroz

Revainrating 5 out of 5

Works well! in Aquarium Pumps and Filters

These air stones work well and are inexpensive. I've only used two of these in my 100 gallon goldfish pond and they have worked for months with no problems and no clogs! If that's important to you, they're not very heavy, so some people might want to weigh them down a bit. It doesn't matter what I need them for and I just add them to create airflow and I don't care if they move a little in the tank.

Pros
  • Good Thing
Cons
  • Zero
