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