Microbe-Lift Bird Bath Clear Two-in-One Water Cleaner – 4 Oz – Safe for Birds, Fish & Frogs – Cleans Outdoor Birdbaths & Fountains – Natural Formula, Prevents Stains & Cloudiness

I use less than they said and it still works great. Can easily go a week or so with no green water! Easy to use.

Works perfectly in my fountain and is eco friendly. No worries about harming the birds and butterflies in my garden.

This solution seems to be working. It’s keeping the water clean better than a previous brand I used. I mix up a gallon at a time so it’s always ready. Now if I could only get the birds to quit using it as a bathroom, it’d be perfect. I’d also love a bigger bottle.

Keep the bath bath fresh for our fine feathered friends! Just a capful and water stays fresh.

Works fair, it's hot here and that make the yucky stuff grow quickly

Works great and safe
