Nualgi Pond Care Organic Digester, 8.8 oz Concentrate for and Water Feature Maintenance, High-Count Bacteria for Naturally Digesting Waste, Treats up to 30,000 Gallons - 100% Safe for All Aquatic Life

I used this in conjunction with the pond drops and beneficial bacteria. My water was green, I could not even see the first layer of rocks! Within 2 days or started to clear, but then we had several storms come thru, so it was green again and tannins from branches and leaves were turning the water brown as well. I bought a second pkg of this product and my water has been beautiful and clear since.

We have a large pond and a large big filter. I like to put this product into the gravel of the bog filter when I see sludge building up. By applying it regularly the sludge doesn't get to build up and the waterfall runs more freely. This is important because if the waterfall backs up it will flow out the side and cause the pond level to drop

This product did not work for my fish pond. Been using for over a month in conjunction with the Nualgi drops and water clarity powder. I have a big filtration system and good aeration but my water still is not clear. Disappointed.

I’ve used Nualgi products for years and added this to the simple line of products that keep my pond super clean and healthy for my fish and lilies! Super helpful customer service!

This organic digester is great my water has never been so clear
