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

It's easy to use really. I keep a solution made up in my garage using an old milk jug. I use it in conjunction with a copper disk and I've had no issues so far. Don't get me wrong, I still have to clean the birdbath. Mostly because they continue to use the restroom in the same place as their communal drinking area. I'm thankful that it's safe for my feathered friends and it does keep the water clearer overall so I think the quality of the product is just find.

Works like a charm! I don't have to scrub the birdbath every week anymore.

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.

This cleaner kept the water clear and the bird bath free from algae for about 10 days. It lasted longer than I expected for the size of container that I used it in.

This is a great product. With just the small recommended amount , my birdbath stays cleaner and the mosquitoes seem to not like it. No more wiggling larvae in the water! The birds don't notice any difference and drink the water and take their baths.

We have a small (about 2-gallon) bird bath that is in partial shade most of the day. the water will turn deep green after less than a week of cleaning and changing out the water. Adding this product did not seem to slow down the problem much.

Love this stuff for my bird baths. I want product that doesn't have toxic chemicals and works. This meets both of those needs.

Works fast. Super easy, just dump in and you’re good. Keeps our fountain clean for so much longer. 💕
