QUALITY AIR STONES
Works great. Can make lots of small bubbles and they come out evenly across the entire stone. Doesn't make a lot of back pressure straining your air pump. I wish they made even longer ones this style from this company. Other long straight air stones I've tried require more air pressure.

Great bubblin stones!
These work great, love the 2 pack. Standard aquarium tube slipped on and held very securly. Very heavy and solid feeling. I put one in my shallow well and one in my settling tank, puts out a lot of air and i only have like a 18 watt 120 pump! If i ever need these again i will get them. They do sink! I know some people had issues with that, but i did add mine on a line with a weight so i can adjust the height in the well. Good solid product. Reccomend

Used these for airation in my aquarium sump for a fluidized bed reactor. Works amazing. Surprisingly small bubbles wich is great, and these don't float which is perfect. Highly recommend these. You do need a big air pump to run these

These are great air stones, the air tubing holds on very tightly and stays in place. They are heavy enough to stay on the bottom of the tank and don't move. Really like the design of these air stones.
