Nualgi Organic Digester, 8.8 oz Concentrate for Pond and Water Feature Maintenance, High-Count Bacteria for Naturally Digesting Waste, Treats up to 8,000 Gallons - 100% Safe for All Aquatic Life

The media could not be loaded. I do t know his long they have been around, but you see results with in a week, water clarity is remarkable, it made stop using, the stuff I’ve been using for the last 10 years, a little pricy, but worth every penny, a little goes a long way!!!

Nualgi products are amazing. I've been using this and the drops. That's it bedsides beneficial bacteria. The water is so clear I was able to spot a koi "tooth" all the way at the bottom. 3.5 feet.

I use this in my guppy pond that has sludge from years of planting water lilies. It works great!

when you need a clean up of sorts just follow directions and you will have a nice clen pond. All Nualgi products are great.

The product works but didn't treat anywhere near 30,000 gallons the advertising needs to be updated.The packaging says 2 tablespoons per 1,000 and the package contains just under 1 cup (16 tablespoons). That treats only 8,000 gallons. Please update the packaging or the advertising."Treats 30,000 Gallons" does not show on the packaging the way it does in this picture.

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

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.

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.
