BioDoser is a semi-automatic dosing system. The system can be used to regularly dispense a preset dose of a liquid pool supplement of your choice. Some examples include Pool Acid, Backup Sanitizer, Ionlife+, Liquid Pool Blanket, and many more. The BioDoser takes the hassle out of regular addition of pool supplements, by doing the job for you. Simply program how much supplement to add, and how often to add it. It’s as simple as that!
