what about the goldfish and the cat that uses the pond as his personal
drinking fountain, while "talking" to HIS fish. will the potash "bother"
them. and then do I apply in the biofalls section or let it filter through
the whole pond first. 350 gallons. getting web site together, including
cat "talking" to his fish.
