This greatly increases the contact time of the air bubbles in the water column

will not disrupt the ionic balance of closed marine aquaria

giving true salinity results when correctly calibrated and greater accuracy than previously attainable

and trace elements in the proper ratios to duplicate the composition of synthetic seawater

Parameters are based on dry salt mixed with RO water
