Microbe-Lift/Sludge Away

Question:

I have a green sludge, left from using Barley pellets to kill algae. I understand that the Microbe-Lift/Sludge Away will digest the residue. Is it safe for my Koi?

If not, can you recommend another product that will digest the organic residue?

Answer:

Microbe-Lift Sludge Away is safe for Koi and Goldfish if used as directed.
It is used in our display ponds on a regular basis.
