Compatibility / Fitment Notes
Bio-Dex Knock Out Yellow is a swimming pool chemical rather than an equipment replacement part. Product suitability depends on the pool's current water chemistry, volume, algae condition, sanitizer program, and the directions on the product label.
Before treatment, confirm pool volume and test the water. Do not assume that one container or one standard dose is appropriate for every pool.
Because pesticide registration and labeling determine legal use, follow the label on the exact container being sold. California registration status should also be confirmed before offering this Bio-Dex product for sale in California.
Installation / Use Notes
Read the complete product label before use. Test the pool water, accurately determine pool volume, and brush visible algae from affected surfaces before beginning a corrective treatment.
Apply Bio-Dex Knock Out Yellow only at the dosage and with the supporting treatment specified on the current container label. Maintain circulation and filtration as directed. Never combine concentrated pool chemicals together in a container, and always add separate treatment products individually according to their respective labels.
Because the current Bio-Dex California registration requires verification, confirm the current legal label and registration before publishing specific dosing instructions online.
