Maintaining clear water and a stable biofilter is essential for fish, coral, and plant life. AZOO's AZOOPLUS BIO XD combines a concentrated mix of nitrifying bacteria designed to kick-start the breakdown of organic waste, feeding residues, excrement, and sludge in both freshwater and saltwater environments. The 8.45 oz bottle makes it easy to dose consistently as your tank grows or changes.
BIO XD bacteria are highly active and ready to go, with no activation step required. After dosing, the bacteria begin to tackle ammonia, nitrite, and hydrogen sulfide, helping to reduce toxin levels in the water and support clearer conditions. In many setups, water appears clearer within 24 to 48 hours as beneficial bacteria establish themselves.
Note: results can vary based on tank stocking, feeding, filtration, and water parameters. If used incorrectly or with incompatible equipment, the product may not perform as expected. Always follow the instructions and observe your tank’s response.
Q: Is AZOOPLUS BIO XD suitable for both freshwater and saltwater tanks?
A: Yes. It is designed for both freshwater and saltwater aquariums and works with a variety of tank sizes.
Q: How soon can I expect changes after adding AZOOPLUS BIO XD?
A: Bacteria begin working immediately; many tanks show clearer water within 24–48 hours, depending on tank conditions.
