Zym Bac™ Nitrifying Bacteria consists of beneficial organisms that establish the biological filtration in your tank. They kickstart nutrient cycling and help correct for ammonia and nitrite levels that might otherwise be harmful to your fish. In fact, they convert those compounds into nitrates - the nutrients that your plants need to grow!
Pour the entire bottle out across your three sets of Growstones® before you plant your seeds - your Growstones® are the perfect environment for these beneficial bacteria to do their job. Very important - after each harvest if you are cleaning your Growstones®, do not rinse more than 1 pod per day! Spacing out cleanings will allow the bacteria time to repopulate and keep doing their job.
