What’s the best way to deal with brush and beard algae?
1. Increase the volume of water changed each week to about 30-50%.
2. Fertilise regularly after each water change, e.g. with JBL Ferropol.
3. If necessary add a daily dose of Ferropol 24.
4. If algae promoting nutrients (especially phosphate) are present in higher quantities, use e.g. JBL PhosEx ultra to keep them under control.
5. Most important is carbon dioxide. Beard and brush algae are always a sign that there is too little carbon dioxide in the water. If a CO2 system is in use, increase its dosage. Alternatively consider installing a CO2 system like JBL ProFlora u401 or m601.
6. Put in fast growing stem plants as nutrient competitors.
7. If there is strong current, reduce it slightly.
