 LITHAQUA is a marine mineral some times referred to as coral however it is calcified seaweed! high in trace elements and carbonates. A superb filter media of porous construction.
LITHAQUA can be used in trickle towers, replace gravel in ponds / filters etc. The high level of carbonates will improve carbonate alkalinity in soft water regions neutralising low acid pH and buffer swings in pH. Use 5 to 10kg per 1000 gallons to restore neutral pH.
We now have 25 kg / 55 lb bags
