![]() As you can no longer buy Dowflake at Univar and the new formula is no longer reccomended due to the Bromine levels ,i recently found a possible substitute at Univar. It is pharmaceutical grade calcium chloride used for dialysis patients. Have been using it in my tank for a couple weeks now and have not seen any negative effects. MSDS actually has on there for Marine tanks
![]() 100% Calcium Chloride!!! |
