What’s the difference between Pure Pond, Pure Pond Bomb and Filter Start Gel?

Filter Start Gel should be used to kick-start brand new filters, or existing filters which have changed to brand new biological media. Pour the gel directly over the media. Pure Pond is a maintenance product which can be used regularly on new and established ponds to help keep water clear, reduce sludge, and keep populations or beneficial bacteria high, and intact. Pure Pond Bomb is a concentrated single dose of bacteria and enzymes. It can be used regularly, or if increasing fish load, washing filter media or replacing bacteria after the use of medications.
