* Tank 1-5 are seriously low in pH, with the water too acid. We have purchased some plastic covered metal mesh waste baskets which will contain Oyster Shells. The baskets will be located in the BioFilters and as acidic water passes over the shells the carbonate will be dissolved which will raise the pH and buffer the water against rapid pH swings. In the mean time we will add slowly 500 g of Bicarb Soda and retest.
** Aquariums will need at least 1/3 of the water exchanged to balance and refresh the water.
