Standard for aquaculture

We use this on our small fish farm for routine maintenance. It is consistent, reliable, and cost-effective compared to other brands we have tried.

Saved my decorative fountain

My outdoor fountain was completely green and slimy. One treatment with this solution restored the water clarity immediately. Very satisfied with the results.

High quality crystals

The purity is evident. No strange impurities or clumping. Dissolves quickly in a bucket of warm water before adding to the main system.

Effective but handle with care

It does exactly what it says for algae control, but the packaging could be more secure. Some powder had leaked into the box upon arrival. Product itself works well though.

Works perfectly for my koi pond

I had a severe algae bloom in my koi pond, and this copper sulfate cleared it up within two days. The crystals dissolved easily, and the fish showed no signs of distress when used according to the dosage instructions.

Great value for pool maintenance

Using this as a supplemental treatment for my swimming pool during hot summer weeks. It keeps the water clear and prevents green tints. Just be careful with the measurement; a little goes a long way.

5 FAQ

Q: Does this stain pool liners?

A: When fully dissolved before application, it typically does not stain. However, pouring undissolved crystals directly onto the pool floor can cause discoloration. Always pre-dissolve in a bucket.

Q: Can I use this to treat fruit trees as mentioned in the title?

A: While copper sulfate is used in agriculture, this specific listing is optimized for water treatment in pools and aquaculture. For agricultural fungicide use, please ensure you follow local agricultural regulations and specific crop guidelines.

Q: Is this safe to use in a pond with live fish?

A: Yes, it is safe for aquaculture and ponds with fish when used strictly according to the recommended dosage guidelines. Overdosing can be harmful to aquatic life.

Q: What is the shelf life of this product?

A: If stored in a sealed container in a cool, dry environment away from moisture, the product remains effective indefinitely as it does not degrade over time.

Q: How much product do I need for a 10,000 gallon pool?

A: Dosage varies based on algae severity, but a general starting point is 1/4 teaspoon per 1,000 gallons. Please consult the detailed instruction label on the package for precise calculations.
