Fine bubble aeration is an efficient technique of aeration in terms

of oxygen transfer due to the large collective surface area

of its bubbles and thus transfer more oxygen to the water per bubble.

Additionally, smaller bubbles take more time to reach the

surface so not only is the surface area maximized

but so are the number of seconds each bubble spends in the water,
allowing it more time to transfer oxygen to the water.

Bubblemac air stones are self-weighted and produce uniform bubbles,

and are also resistant to clogging.
