Excellent product, the pond water is crystal clear, you can see the bottom of the pond, the pond is very healthy. Coco Ego-Aquirre – Ontario, CA Science That Works! The "brute force" use of chemicals is recognized as an expensive and often environmentally harmful way of eliminating organic waste. In the early 90's Doctor Bernard, PhD Microbiology, developed the original Bio-Pure formula, so beginning a new era of microbiology-based waste management products. Dr. Bernard’s philanthropic goal was to improve fish & shrimp yield by working with bacteria to eliminate the nitrogenous waste excreted into their water. His work produced the first cost-effective, organic way of improving water quality for third-world fish farms. The bacteria in Bio-Pure was rated best out of 132 entries in a 3-year United-Nations-funded study designed to determine which dual bacteria and enzyme action was the most effective in breaking down and digesting organic waste in two product categories. Bio Pure Pond Aquarium is a Proprietary Microbial product which works (24/7) in aerobic and anaerobic conditions. All-natural microbes (multi-species), carriers, nutrients, specialized enzymes. The microbial/bacteria concentrate is a blend of microbe species that focus on substrate waste and water clarity. One microbe becomes 9 - 10 million waste digesting microbes in 24 hours & safe for fish, plants, and people. This water conditioner contains beneficial bacteria to help maintain a stable pH level of the pond or aquarium. Question: How to reduce NITRATES? The only immediate way to reduce NITRATES is to make a water change and begin using Bio-Pure regularly. Bio-Pure digests dead organic matter which reduces ammonia, which reduces nitrates, which reduces water changes & maintains other water parameters to keep your aquatic environment & water quality at its best. CLOUDY WATER!!! Bio-Pure is not an immediate gratification product like chemical cleaners are. Your aquarium or pond will experience a mild to extreme microbe bloom the first 1-3 days, depending on how dirty the aquarium or pond environment is. Then, as microbes gather the buoyant waste and seed into the system, the environment will clear; prepare to be AMAZED!!! The only Aquatic Therapy Cleaner for aquarium; pond beneficial bacteria treatment; pond beneficial, aquarium beneficial, and pond / aquarium water treatment, "GUARANTEED" improves pond / aquarium water quality. Enhancing the clarity and reducing the frequency of water changes save time & money! Top Review Discussion Oscar A.Hernandez - 1.0 out of 5 stars product crap this product instead of clarifying the water gave me almost mud color, therefore I in my opinion cheated me. So simple and used other products that if they clarify the water this crap does not work. I repeat it I change the color almost mud Answer: Customer Purchased Sunday 7/24/2022 – Amazon shipped Monday 7/25 – Delivered Wednesday 7/27 – we assume customer used Bio-Pure same day it was delivered and then was reviewed the next day, 1 day later!
