High quality crystals
The crystals are vibrant blue and very pure. I use this for aquaculture treatments in my koi pond and have had excellent results without harming the fish when dosed correctly.

Perfect for my orchard
Used this to make Bordeaux mixture for my apple trees. It dissolved easily and seems to be working well against fungal issues. Great value for the price.

Fast shipping and good packaging
Arrived quickly and the container was sealed tightly to prevent moisture exposure. Exactly what I needed for my gardening projects this season.

Effective algaecide
Does exactly what it says. Cleared up the algae in my decorative fountain. The only reason for 4 stars is that the measuring scoop could be included.

Works great on pool algae
My pool had a stubborn green tint despite regular chlorine use. A small amount of this cleared it up within two days. Just follow the dosage instructions carefully.

Standard grade for agriculture
Been using copper sulfate for years on my vineyard. This batch is consistent with what I expect. Good solubility and effective coverage.
Q: How much do I need for a 10,000 gallon pool?
A: Dosage varies based on algae severity, but typically 0.5 to 1.0 ppm of copper is recommended. Please consult our detailed dosage chart or a pool professional for exact calculations.
Q: What is the shelf life if kept sealed?
A: If stored in a cool, dry place with the lid tightly sealed, Copper Sulfate Crystals have an indefinite shelf life as they do not degrade over time.
Q: Does this come with a measuring spoon?
A: No, the product does not include a measuring tool. We recommend using a dedicated plastic or glass measuring device, as metal can react with the chemical.
Q: Can I use this directly on edible fruit trees?
A: This product is commonly used to create Bordeaux mixture for fruit trees. Please adhere to pre-harvest intervals and application rates specified for edible crops.
Q: Is this safe to use in a swimming pool with people?
A: Yes, when used according to label directions and proper dosage guidelines. It is important to allow adequate circulation time before swimming.
