Coralife Marine PURE Water Care Bacteria Supplement, 4 Pack

Give your saltwater tank a healthy start with Coralife PURE Water Care Bacteria Supplement. Coralife PURE contains millions of beneficial living marine bacteria and enzymes that will live on aquarium surfaces and help break down the ammonia and nitrite created by fish waste and excess food. These enzymes can also help break down organic sludge that often causes poor water clarity. PURE is easy to dose and comes in a time-release ball, so it cannot be overdosed—for new aquariums, add two balls per 30 gallons or less of water. To maintain a healthy and clear aquarium, add one ball per 30 gallons of water per week. Plus, you can place PURE directly in your tank, or hide it inside your aquarium’s filter (sold separately).
