Product Review

Note:

Please soak the air stones in water for about 15-30 minutes before usage.
A bigger air stone needs a more powerful pump to produce more bubbles. 4 Inch airstone needs the air pump of at least 10W.
If it doesn't have bubbles in one part, please change the air pump of higher power.
After a long-term use, clean your stone regularly so that it will be most effective.
Replacing the air stone every six months as they get clogged with dust, bacteria, and algae.
