Kallax balls are the same as the popular Lubao balls except in a smaller less potent size. Lubao balls can be a bit much for the bioload on smaller tanks or a newly established tanks beneficial bacteria cycle. Kallax is recommended for tanks below 10 gallons, smaller colonies, or if you just want the same great benefits of Lubao balls but with less bioload on your tank.
Kallax balls provide a constant grazing source in your tank. You will notice your shrimp are always grazing around the tank looking for food. If your tank is well established with plenty of moss, algae and green walls, this may be enough grazing food for the shrimp. But if your tank isn't established with biofilm and algae, your colony is large and they eat all the algae, or you just want to ensure your tank has sufficient grazing material for your shrimp's health and breeding, then Kallax balls are a great way to achieve this. Kallax balls are a supplementary grazing food and not meant to replace your daily staple shrimp foods.
As with all new foods and additives in our precious shrimp tanks, Shrimp Envy recommends you monitor water parameters and maintain a proper water change schedule to ensure the health of your shrimp colony.
Please soak the Kallax in RO water for 2-3 days, changing the water daily to release excess tannins and allow biofilm to start growing on the ball. Do not rinse or wash the ball after soaking, just drop it in your tank. Do not be alarmed when the ball becomes fuzzy white, that is the precious biofilm growing. Each Kallax will last up to 30 days in your tank before it starts stinking badly and should be removed.
