These disgusting traits are caused by the build of organics that cause cyanobacteria and algae that are traditionally treated with harmful, concentrated chemicals and algaecides. DrTim's Aquatics Re-Fresh provides a 100% natural alternative method that helps clean and maintain a healthy fish pond. Our potent liquid solution contains a powerful combination of beneficial bacteria that combats algae, scum, slime, grunge, cyanobacteria, and cloudy water by reducing organic waste and residue that result in unpleasant odors. Our completely natural formula provides a quick, effective solution for cleansing and preserving pond water and is safe for fish and aquatic plants. We recommend using DrTim's Aquatics Re-Fresh weekly before bacteria, slimy film, and discolored water. Re-Fresh is a sanitizing, revitalizing solution that contains a potent mixture of beneficial bacteria and naturally eliminates algae and cyanobacteria. Though these growths are traditionally treated with strong chemicals, DrTim’s Aquatics Re-Fresh provides a safe, effective alternative treatment method that is 100% natural and completely safe for fish and aquatic plants. Re-Fresh will give you fresh, clean pond water by reducing organic waste from fish and organisms, which not only is unsightly but can also disrupt the health of the pond’s ecosystem. Proper dosing can revitalize old, green/brown water, preserve clear water, and keep water odor-free. For best results, we recommend adding Re-Fresh on a weekly basis with a maximum dose of 1 ounce per 60 gallons of water to maintain clear and clean water that enhances fish, organism, and aquatic plant health. The condition of every pond varies, so it may be necessary to add Re-Fresh more frequently (every other day) to achieve desired results.
