ALDON Copper (II) Sulfate Solution, 1M, 500mL - The Curated Chemical Collection

Great product! Did exactly what it was supposed to do! Great value for your money!

So, we bought a house. Yippee. The only problem is the small area of pink mold near the drain. I bought EVERYTHING I could find that said it killed mold. Sprays, gels, cleansers, etc. The mold kept coming back. I was on YouTube and saw a video that said "Buy this to kill all mold, immediately!!" So, I figured "I've already spent enough to buy a new tub, what's another $20? It arrived still sealed, not a drip in the bag. I mixed it with hot tap water and just tossed it in the area and went to bed. I woke up, gave it a good rinse as the bottle said do not get on skin, and Wow, it was gone!! I've had this problem for the entire 8 years I've had this house. I called a bathroom remodeler and they wanted a ridiculous amount of money to tear out the old tub and replace it. Then he started talking about "we'll probably have to replace the studs, which means replacing the walls, it might affect the ceiling..." I cut him off and told him to leave and just started putting a towel over the spot when I showered. Now it's gone. Best part? I only used a tablespoon of this beautiful blue liquid!! It saved me from demolishing the entire bathroom! Now I'm asking friends if they have any mold in their house just to show them how amazing this stuff is. Science is wonderful, huh? Now if they can create something to eliminate my mortgage & insurance payment!! 5 HUGE STARS!! THANK YOU, AMAZON!! 👏👏

Worked great! Better than expected!

A coworker had told me it would remove algae from my pool and they were correct it was gone in 24 hours works great to keep my pool looking super crystal clear.

I bought this to help with my swimming pool, I wasn't sure what I was ordering but a friend told me I could use it for my pool. I actually should have ordered the crystals instead of the liquid. But it did help my pool stay clear and blue but it didn't last but a couple of days, I was under the understanding that this would keep my pool pretty and clear and blue and I think I should have got the crystals because they are supposed to last a long time in-between dosages. It's like this was a watered down version! It did work and my pool was pretty blue but it only stayed that was for a few days, like 3 or 4 tops. I was expecting to last way longer but like I said I wasn't sure what to order and got the cheaper product, but I wasn't completely disappointed.

Plumer recommended Copper Sulfate to help eliminate roots in sewer drainage. I'm hoping this takes care of the problem with the roots with regular use.

I purchased these for electroplating use and so far, so good. It seems to be good quality and was definitely worth the money vs. making my own.

Excellent product and very good quality I recommend it

Tout est parfait

Suits me perfectly with what I needed it for
