DIY Quick Cheap Airstone

when i am going to clean up my tank i saw my air stone is broken and not working

so i decided to build one because i don't want to go outside so things i used in this



1. Airline pipe
2. a Gravel (stone)

use a stone or any gravel to close end of pipe so that air cannot escape easily

and create pressure inside pipe for escape from tiny pin size holes.

use any pin to make holes in airline create as many holes as you can

and after that test if it doesn't make bubbles make holes little big so air can escape

Done :D
