Product Description
Granular Algae Control With Water Quality Support
SeClear G is built for pond, lake, canal, and managed-water applications where algae control alone is not enough. Its granular copper sulfate pentahydrate formula can be broadcast directly over target growth or dissolved for spray, drip, injection, or metered use, giving applicators flexible ways to reach surface mats, bottom growth, and difficult algae pressure while also helping bind dissolved phosphorus and suspended solids.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| Granular copper-based formula | Gives applicators a dry, flexible format for targeted algae treatment. |
| 58.9% copper sulfate pentahydrate | Delivers labeled copper activity for a broad range of nuisance algae. |
| Surface and bottom algae fit | Useful for planktonic algae, filamentous mats, Chara, Nitella, and Starry Stonewort. |
| Broadcast or dissolved use | Supports direct granule application, spray application, drip, injection, or metered programs. |
| Water quality enhancement | Helps reduce dissolved phosphorus and suspended solids as part of a proactive program. |
Directions & Dosing Snapshot
| Use Case | Label Rate | Application Notes |
|---|---|---|
| Planktonic algae | 0.10 to 1.0 ppm metallic copper; 1.8 to 18.0 lb product per acre-foot | Base treatment depth on where suspended algae are present. |
| Filamentous algae | 0.2 to 1.0 ppm metallic copper; 3.6 to 18.0 lb product per acre-foot | Higher rates may be needed for heavy blooms or clumped surface mats. |
| Macrophytic algae | 0.4 to 1.0 ppm metallic copper; 7.2 to 18.0 lb product per acre-foot | For Chara, Nitella, and Starry Stonewort; apply close to algae growth. |
| Static or minimal-flow water | Acre-feet x desired metallic copper ppm x 18.0 = lb product | Determine surface acreage and average treatment depth before calculating. |
| Flowing water | CFS x desired metallic copper ppm x 1.5 = lb product per hour | Maintain 0.10 to 1.0 ppm metallic copper for 1 to 3 hours. |
| Dissolved application | 1 lb product to 2 gal water or greater with moderate to high agitation; 1 lb to 4 gal water or greater with low agitation | Dissolve before spray, drip, injection, or metered application. |
Always follow the full label for complete directions, restrictions, and site-specific requirements.
Comparison Table
| SeClear G | Standard Copper Sulfate Granules | Liquid Copper Algaecide | Beneficial Microbe Program | |
|---|---|---|---|---|
| Active ingredient / approach | Copper sulfate pentahydrate plus water quality enhancement | Copper-based algae control | Varies by label | Biological organic-load management |
| Primary use fit | Surface algae, bottom algae, Chara, and water quality programs | Varies by label | Varies by label | Long-term sludge and nutrient pressure support |
| Use pattern | Broadcast granule or dissolve and apply | Usually granular broadcast | Usually spray or subsurface application | Routine maintenance applications |
| Rate basis | Algae type, acre-foot, ppm metallic copper, or CFS | Varies by label | Varies by label | Varies by product and pond conditions |
| Best-fit shopper | Professionals needing algae control plus phosphorus and suspended-solids reduction | Basic copper treatment users | Applicators preferring liquid handling | Owners reducing organic buildup over time |
Why Choose a Granular Water Quality Algaecide?
- Targeted algae contact: Granules can be directed toward mats, bottom growth, and specific treatment zones.
- Flexible application: Use it dry or dissolved depending on equipment, site layout, and algae location.
- Better program fit: Pair fast algae knockdown with beneficial microbes to help digest dead biomass and reduce the organic fuel that can drive repeat blooms.

Good product to eliminate and control algae. Have used it for years on my 1/5 acre pond. Easy and best price online anywhere.
Verified Purchase
Just spread the granules evenly over the lake, plant growth reduced in about 10 days.

Live in Montana, have a lake/pond on our 148 acre campground that has been in the family since 1947. I’ve used this product for the last 6 years, it is the only stuff that kills the algae for more than a few weeks. Most other product I tried only lasted a week or two at best. I use this first, then apply NT-MAX lake treatment and I do not use any colorants at all. Price is great and lake looks excellent. Happy camper again!
Verified Purchase
Use this on two of our HOA ponds. We apply it using a hand spreader and see results in about 2 weeks. Controls all kinds of algae.
Verified Purchase
The crystals do a great job. Very happy with my purchase.
Verified Purchase
I apply with a hand cranked fertilizer spreader which spits the granules around the edge of my shoreline. Does the job.
