Why do some LFS use airstones in their tanks when bubbles are supposedly harmful to SWF?
MYTH....
Bubbles are not harmfull to saltwater or any body of water, they actually assist in oxygenation..same as powerheads, the only difference is the GPH ratio and the jet-strem.
The only time i would consider micro-bubbles to be bad..is when water is polluted in proteins,impurities,nitrogeous compounds, and when turbulance is limited, thus becoming toxic to marine organisms. especially fish with gills..
the reason why LFS still uses them is, oxygenation economics..
