Diamond Control – Spa Stain & Scale Preventative + Clarifier (16 oz.)

Help Prevent Mineral Stains, Scale and Dull-Looking Spa Water

Diamond Control is a liquid stain-and-scale preventative and clarifier specifically prepared for spas and hot tubs. It helps reduce the tendency of dissolved minerals to create staining and scale while also helping the filtration system capture fine suspended particles that can contribute to cloudy or dull-looking water.

Minerals such as calcium, iron, copper, and manganese may be present in well water and municipal water even when the source water looks perfectly clear. Changes in pH, alkalinity, sanitizer, temperature, and calcium hardness can encourage those minerals to discolor the water or form deposits on spa surfaces and water-contact equipment.

Regular preventative treatment is especially useful for hard-water areas, mineral-rich well water, fresh fills, and spas with a history of scale or discoloration.

Important: Diamond Control does not replace proper sanitizer, oxidation, filtration, water balancing, filter cleaning, or periodic water replacement. It does not lower the calcium-hardness reading or physically remove dissolved minerals from the water.

📋 How to Use

Always follow the directions and safety precautions printed on the current physical product container. The bottle label takes priority over generalized online guidance.

Before Treatment

1. Determine the spa’s actual water capacity.
2. Review the dosage and application frequency printed on the physical bottle.
3. Test the source water or spa water for pH, total alkalinity, calcium hardness, sanitizer, and metals when applicable.
4. Confirm that the circulation and filtration systems are operating properly.
5. Inspect and clean the filter cartridges if they are dirty or overdue for maintenance.

Application

1. Shake the bottle when directed by the current label.
2. Measure approximately 1 fluid ounce per 500 gallons of spa water, provided this dosage is confirmed on the physical bottle.
3. Add the measured product to the spa water with circulation operating.
4. Distribute the product according to the bottle directions.
5. Allow adequate circulation before adding another water-care product.
6. Add each chemical separately; never mix concentrated spa chemicals together.
7. Continue normal sanitizer, oxidation, filtration, and water-balance maintenance.
8. Repeat the treatment at the frequency printed on the physical bottle.

Spa Capacity	Approximate Treatment
250 gallons	½ fl. oz.
300 gallons	0.6 fl. oz.
400 gallons	0.8 fl. oz.
500 gallons	1 fl. oz.
1,000 gallons	2 fl. oz.

Dosage verification: The present Southern Leisure listing specifies 1 fluid ounce per 500 gallons at startup and every two weeks. Retain that schedule only if it matches the current physical bottle.

Do not enter the spa until the water is clear enough to see the bottom, the sanitizer and water-balance readings are within their required ranges, and any waiting period printed on the applicable product labels has passed.

If Staining or Scale Is Already Present

1. Determine whether the deposit is soft residue, hardened calcium scale, or mineral staining.
2. Test pH, total alkalinity, calcium hardness, sanitizer, and source-water metals when applicable.
3. Correct the underlying water-balance problem.
4. Clean the filter cartridges and confirm adequate circulation.
5. Use only a surface cleaner or corrective treatment approved by the spa manufacturer.
6. Contact Southern Leisure if the deposits are severe or the cause is uncertain.

Diamond Control is primarily preventative. It should not be expected to dissolve severe existing scale or remove every established stain.

💬 Southern Leisure Says

The best time to address mineral stains and scale is before they become visible. Clear-looking source water may still contain calcium, iron, copper, manganese, and other dissolved minerals.

Diamond Control helps control those minerals and reduce their tendency to form deposits or discoloration. Its clarifying component performs a separate job by gathering fine suspended particles so the filtration system can capture them more effectively.

Use the correct measured amount, maintain balanced water, and keep the filters clean. Diamond Control supports the water-care program—it does not replace it.

🧼 Care & Maintenance

❓ Frequently Asked Questions

What does Diamond Control do?

It helps prevent mineral-related staining and scale while its clarifying action helps the filtration system capture fine suspended particles.

Is Diamond Control a clarifier?

Yes. The product’s front label identifies it as both a stain-and-scale preventative and a clarifier specifically prepared for spas and hot tubs.

Does it remove minerals from the water?

Do not assume that it physically removes dissolved minerals. It helps control minerals and reduce their tendency to form stains or deposits. The clarifier helps filtration capture suspended particles.

Does it lower calcium hardness?

No. It does not lower the calcium-hardness reading. If calcium hardness is too high, the underlying water condition must still be corrected.

How much should I add?

The current Southern Leisure listing specifies approximately 1 fluid ounce per 500 gallons. Confirm this dosage against the current physical bottle before use.

How often should I use it?

The current listing specifies treatment at every refill and every two weeks. Retain and follow that schedule only if it matches the current bottle.

When should I add it during a refill?

When permitted by the physical label, add it early in the startup process with circulation operating. Allow it to circulate before adding another chemical.

Can I add it with other chemicals?

Do not mix concentrated chemicals together. Add each product separately and allow adequate circulation between applications.

Does Diamond Control sanitize the water?

No. Continue maintaining the sanitizer required by the spa’s water-care system.

Is it a shock or oxidizer?

No. Use a compatible shock or oxidizer separately to address organic contamination.

Can I use it with chlorine or bromine?

Confirm compatibility on the current physical bottle. Publicly available manufacturer literature does not specifically list compatible sanitation systems.

Can I use it with FROG @ease?

Use it only if permitted by the Diamond Control label and the instructions for the exact FROG @ease system. It does not replace SmartChlor cartridges, mineral cartridges, FROG test strips, filtration, water balancing, or the required oxidation schedule.

Will it clear cloudy water?

Its clarifying action may help filtration capture fine suspended particles. It will not correct cloudiness caused by low sanitizer, unbalanced water, excessive calcium hardness, dirty filters, inadequate circulation, heavy organic contamination, or old water.

Will it remove existing stains?

Diamond Control is primarily preventative. Established mineral stains may require a separate corrective treatment approved for the spa surface.

Will it remove hardened scale?

No. Severe scale may require water-balance correction, approved descaling procedures, surface cleaning, or professional service.

Can I use it in a swim spa?

Use it only when permitted by the physical product label and the swim-spa manufacturer. Calculate the dosage from the swim spa’s actual water capacity.
