I have been using Beneficial Bacteria for Ponds which has been working effectively. However, seems that muck is accumulating now. Is is safe for fish and plants to use Muck Reducer and the bacteria together? It is safe. Muck Reducer is a bacteria based product. Let me restate my question. How do I kill the brown algae, that is in our holding tank (600 Gallons)? We have a pondless waterfall.

Use the EcoBlast on the rocks. Pull off the algae and then treat the rocks. Or turn off and let the sun bake the algae off. Remove it and don’t let it get into your basin. Or use MicrobeLift Algae way 5.4 on a regular gasin.
