Nualgi Beneficial Bacteria, 16.9 oz Enzyme Bacteria for Freshwater & Organic Ponds, Starter Bacteria for Outdoor Water Gardens, Natural Pond Stabilizer for Fish, Pets & All Aquatic Life

I have used Nualgi for many years since they started selling. This is a Great product that keeps my Koi pond in super condition.Once a week all the time keeps everything in balance. You know, you don't need a pond light to kill algae and debris. I never use it. Nualgi takes care of everything. Now they came out with a new product Nualgi Bacteria once a week. I have started using it. This keeps all debris under control and gives the necessary bacteria that Koi ponds need. You will be very pleased after using this product,

Love this brand. Pond is always clear

I have about a 2500 gallon pond that is directly in the sun. In the summertime it gets so much algae that there's a half inch layer over the top. This Nualgi Ponds product definitely helps keep the algae levels quite a bit lower. My water is green but still able to see into it. Before treatment you could see nothing. I'm sure if I had some shade it would work great.

i have used this company 's chemicals for my 2000 gallon pond for 6 months. I am completely satisfied with them and I will continue to use them

I have been using this product along with Nualgi Ponds and my pond has really kept so clear. The algae growth is at a minimum. After a big rain I used this and the water cleared up so quickly. I am happy with the results.

Unbelievable product, I have a pond that has been difficult to maintain, this product has made a huge difference and is easy to apply.

Helps keep the pond crystal clear, I would not use any other product.

people are desperate and will try anything to clear up their ponds. This stuff might work in a perfect world but I have been though 2 bottles and it didn't work for me. Keep searching the web for things you want to hear. Im in the wrong business. Good luck.
