Appropriate, long-term algae control.
Excessive algae growth always occurs when a surplus of nutrients (phosphates and nitrates) are present in the water. That’s why long-term algae control works in two steps: it combats algae with the anti-algae agent JBL Algol, then in step 2 it safely binds the nutrients. For this purpose JBL PhosEx ultra is ideal. Adding algae-eating animals, such as sucker catfish, shrimps and snails can also be a great help.
