Medium pore air stones made in the USA.
These diffusers are the highest-quality ceramic-type air stones machined from a block of glass-bonded silica. These air stones don't need expensive air filters as dust and dirt particles up to 30 microns will pass through the system.
With an air resistance of less than .25psi, they are compatible with economical low-pressure blowers. Because of the uniform medium/fine bubble these diffusers produce they are very resistant to clogging. The best way to clean them is in an acid bath which will remove any build-up of calcium or bacteria.
Note: that water pH more than 9.0 will shorten the diffuser life. Self-weighting when used with typical tubing lengths.
