Mellbree Bird Bath Copper Disc, 0.6mm Reinforced 99.99% Pure Copper Cleaning Disk for Physical Safe Clean Water All-Season, Universal Fit for Outdoor Birdbaths, Bowl, Bird Bath Solar

I have one of them in a bird bath and it is working well! Put it in on Monday and it is now Friday! Other than splashing out surface debris, the water has remained clear and clean! My birdie friends thank you! 😃

I’m surprisingly pleased with these copper disks. I get quite a few birds in my birdbath and it gets icky quickly especially since it sits in the sun. When I received these discs, I scrubbed the bath well and placed one in the bowl. I always put in fresh water everyday. It’s been 6 days now and I’m just starting to see signs of algae starting to show up. This is a huge improvement and I’m a believer. Much less scrubbing! I recommend this product.

Who would have thought these little disks could keep water so clean! Flawless functionality and cute presenting! Highly recommend product and seller…exceptional value!

I struggle with algae even though the water evaporates due to our excessive heat here in AZ. I only bought one because I really didn't believe it would make a difference. I was wrong! First it is really pretty in the water. Secondly, it does make a difference from the get go. I was astonished. However, with all that said, do not let the disc be exposed to sun and air and not covered with water. I didn't tend to our birdbath for 3 days and the disc was exposed to the elements and turned burnished which is what copper does naturally. I tried to clean it and return it to the original condition but was not successful. I will reorder at least a 2 pack soon and be more careful. And if I learned anything from Trump's Washington Monument reflecting pool fiasco.....hydrogen peroxide in the bird bath water does not harm the disc and attacks algae growth. I give the deep birdbath fresh water every 2 days and add hydrogen peroxide every 3 weeks to the water without harming the wildlife and it keeps the birdbath algae free.

I’ve only had these Mellbree copper discs in my birdbath for about a month, and they’re definitely doing something. The water stays cleaner for longer, and I’m not seeing as much buildup as before, which is nice. But let’s be real — it doesn’t magically clean everything. You still get some stuff settling at the bottom, and it’s not like the birdbath suddenly becomes self‑maintaining. It helps, but it’s not a full‑on “never scrub again” situation. For the price, it’s solid, especially since you get two discs and they’re pure copper. Just don’t expect it to replace actual cleaning. Bottom line: Good helper, not a full solution. Worth it, but not mind‑blowing.

Was doubtful this copper disc would perform as advertised but I’m a believer now. I was tired of scrubbing birdbath every day, as it sits in sunlight most of the day. So I bought this Melbree product, scrubbed the birdbath with just a brush (didn’t have time to use bleach to really start clean as I was leaving for vacation, so some algae stains remained), popped in the disc and went away for a week. Came home to clear water, albeit, not a full birdbath since the birds used it. Water was not even green, algae colored! I’m convinced! This pic shows 4th day! since I returned ~ no scrubbing and refilling every day! Worth the price in gold, or copper, as it were!!

I have noticed a difference in the amount of algae in my birdbath. Water is definitely clearer I change it everyday but that is my choice could probably last a couple days

The copper disk definitely helps keep the water cleaner — like, it slows down the slime, the funk, and whatever mysterious bird soup forms in there. But let’s be real: it does NOT clean all the water. You still gotta roll up with your scrub brush like you’re doing a tiny spa day for birds. The copper is legit, the disc is sturdy, and it does reduce buildup. It just doesn’t replace actual cleaning unless your birds are unusually tidy (mine are not). So yeah: helpful, but not a miracle. Rating: 4/5 — great assist, but you’re still scrubbing like a medieval peasant.

Great item really works.

Idéal pour la fontaine

Works well in the bird bath. Keeps water clean. I rinse out the bird bath a few times a week, and there is no slime. Would highly recommend.

These work. Kept the algae down a lot. Ready to use next summer. Great quality

Was sceptical but we have a bird bath and a water tray for our visiting hedgehogs these needed jet washing at least weekly due to algae but after placing these in them the maintenance is significantly reduced
