Erva Copper Bird Bath Purification Disk - Made in USA

Does the trick! Water clear no green!

PERRRRRFECT! I bought my first bird 🐦 🦜 bath that I ALWAYS wanted (I'll review that in a moment) - I didn't know I needed something to keep the algae away! I had no idea that this would even happen, it's not something I thought of before even after changing the water every 2 days! So I "Googled" how to get rid of algae in bird baths and this is what almost everyone said - a copper disc so I got one, and lemme tell ya IT WORKS GREAT! I was kinda surprised it worked actually. But I'm glad the remedy wasn't an expensive one. There were some other suggestions to rid algae - I stuck with the copper disc 😊

Don't waste money on buying something to put in your water. This actually works! I wasn't cleaning the bird bath every other day. About two or three weeks I would clean it with very little algae. I love it!!!

Got these because I got tired of cleaning the bird feeder Bowl every few days. Easy, just dropping the ball. Doesn't quite clean the whole Bowl but works good

Wow, I would not have believed it unless I tried this out in my bird bath! No more scrubbing every few days in the summer when slime and algae start to form! Yes I still clean my bird bath but this copper disk kept the water cleaner for so much longer, I was amazed! Great quality and easy to use, just drop it in!!

Advertised to prevent algae growth in bird bath. Not! Well, to be honest it does work..if you count only preventing algae 1/2” around the copper disk not the entire bird bath. Waste of money unless you buy maybe 10-12 of them to cover the whole bath.

I have to use a heated bird bath otherwise it will freeze solid in the winter. Because the water is warm all the time algae growth occurs in two to three days. I've now had this disc in the bath for seventeen days now and there is not a sign of any algae. This thing really works and it's made in the USA

I have a nice concrete pedestal bird bath with an embedded pebble texture that is a real mess and impossible to keep clean in the summer. I saw this copper plate and the reviews all sounded good so I gave it a try. I first gave the bird bath a good scrub and bleached it to make sure there was no live algae left. Put the disk in and filled it with clean water. Over the first week I was amazed to see that the interior of the bird bath got cleaner looking each day. I really expected to see some algae but there has been zero algae growth and it’s in direct sunlight almost all day. This works great! Update: after a few weeks I’m reducing my rating to 3 stars. The reason is that the bird bath is still growing algae. Maybe not as fast as it did before I placed the disk. Have to say I’m disappointed since I even moved the bird bath into the shade whereas it was in full sun before. My recommendation is to just throw a handful of pennies in the bird bath. In fact that is what I did for another one I have.
