    Specialty Pool Products

    Dive into impeccable pool care with HTH's™ specialty pool products. This extensive range of specialty items designed for swimming pool maintenance offers an unrivaled blend of quality and efficiency. They are the go-to products when your pool requires more than just a simple cleaning or a basic chlorine treatment!

    Each product in our wide range of specialty pool chemicals is designed for comprehensive swimming pool maintenance. These products encompass everything from pool opening and closing products to fast-acting clarifiers and phosphate removers, all of which have been developed to ensure the optimal performance of your pool, irrespective of its type or size.

    For instance, the Pool Care Kit is an all-in-one package that allows you to test, shock treat, control metals, and prevent algae in your pool. You can use the kit in any type of pool, for both pool opening and closing, and it is particularly efficient at treating up to 20,000 gallons of water!

    Our specialty pool products also include products to keep your pool filter at optimal performance. For your diatomaceous earth (D.E.) filter, you can use the the Pool Filter Aid to trap even the tiniest particles, ensuring your pool water remains crystal clear. For your sand filter, you can use the Pool Filter Sand, which has undergone a rigorous washing process to keep your swimming water clear. For the best results, use the Filter Cleaner 2 - 3 times per season to effectively clean your cartridge, sand or D.E. filter.

    If you're dealing with stubborn algae, you can rely on specialty pool chemicals like Phosphate Remover, which removes the phosphates that algae survive on. Drop Out Flocculant, which drops dead algae and dirt to your pool's bottom for seamless vacuuming, will also be handy. HTH also has specialty pool products that ensure dissolved metals don't stain your pool surface.

    You can get the clarifier products if you want specialty pool chemicals to keep your pool water sparkling. These are designed to quickly restore clarity and sparkle to cloudy or hazy pool water and improve filter efficiency.

    Our brand's commitment to quality, convenience, and effectiveness sets HTH's specialty pool products apart from competitors.

    Frequently Asked Questions

    • What are pool specialty chemicals used for?

      Specialty pool chemicals address specific problems that routine sanitizers and balancers cannot fix on their own — such as metal staining, calcium scaling, phosphate buildup, foam, water cloudiness, algae prevention, and heat/evaporation loss. They complement a complete pool care routine.

    • What specialty pool chemicals are available from HTH?

      HTH's specialty pool chemical line includes: Pool Clarifier Advanced, Drop Out Flocculant, Metal Stain and Scale Control, Phosphate Remover, Clear Defense Algae Preventer, Liquid Solar Blanket, Hydra Nourish Water Conditioner, Filter Cleaner, Pool Filter Sand, and D.E. Filter Aid. These products address specific water quality and maintenance issues that routine sanitizers and balancers cannot solve.

    • When should I use a pool clarifier vs. a flocculant?

      Use clarifier when your pool is mildly hazy and you want to improve it gradually using normal filtration over 24–48 hours — no extra effort required. Use flocculant for extremely cloudy water when you need rapid results (for an event or after algae treatment). Flocculant should only be used with a filtration system that has a vacuum-to-waste setting. This allows the settled debris to be removed directly from the pool rather than passing through the filter, where it can clog or damage the filter. Flocculant is faster but more labor-intensive; clarifier is easier but slower.

    • How do I treat pool stains without damaging the surface?

      First, identify the type of stain. Organic stains are typically green or brown and can often be removed with chlorine. Metal stains vary by source: iron typically causes rust or orange discoloration, while copper can cause blue-green staining. Use HTH™ Pool Care Metal, Stain & Scale Control to treat metal stains.

    • Why should I use a liquid solar blanket if I already have a physical pool cover?

      A physical cover is more effective for heat retention when the pool is completely unused for extended periods. A liquid solar blanket is ideal when you want continuous evaporation protection without the hassle of daily cover removal and replacement. Many pool owners use both: the liquid solar blanket during active swim season and the physical cover for overnight or off-season storage.

    • How do phosphate removers work and will they cloud my pool water?

      HTH™ Pool Care Phosphate Remover uses a lanthanum-based formula that binds to phosphates in the water, causing them to form a fine white cloud. This temporary cloudiness is normal and expected. The precipitate is then captured by your filter over 24–48 hours. Clean or backwash the filter after treatment.

    • Can I use multiple HTH specialty chemicals at the same time?

      As a general rule, add specialty chemicals one at a time, waiting at least 4–6 hours between additions, just as you would with balancing chemicals. Certain combinations can interfere — for example, do not add clarifier at the same time as phosphate remover (both cause precipitates), and do not apply algaecide simultaneously with shock. When in doubt, read labels for compatibility notes.

    • How do I reduce pool chemical and water costs during the swim season?

      Several HTH specialty products directly reduce ongoing costs: Liquid Solar Blanket reduces evaporation (less water and chemical refill), Chlorine Stabilizer reduces how often you need to replace chlorine burned by UV, regular filter cleaning maximizes filtration efficiency, and weekly Phosphate Remover application reduces algaecide and shock demand. Together, these reduce your overall chemical spend significantly.

    • Why is my pool cloudy?

      Cloudy pool water is a signal to test before you treat. Common causes include poor filtration, high pH or total alkalinity, organic contaminants and early algae growth. Start with HTH™ 6-Way Test Strips, correct any imbalance and check the filter. If balanced water is still hazy, HTH™ Clarifier Advanced helps the filter capture fine particles. For severe cloudiness, HTH™ Drop Out Flocculant drops debris to the floor for vacuum-to-waste removal.

    • How can I clear cloudy pool water fast?

      Test and balance the water first. For dull, hazy or moderately cloudy water, dilute HTH™ Clarifier Advanced as directed, add it around the pool and to the skimmer, and run the filter for at least eight hours. For severe cloudiness, HTH™ Drop Out Flocculant can restore clarity overnight: run the pump for two hours, let particles settle overnight, then vacuum them directly to waste. Follow the label for your pool volume.

    • Will pool clarifier clear green pool water?

      Not by itself. Green water usually points to active algae, whereas a pool clarifier is designed to help the filter capture fine suspended particles. Treat the algae first with an HTH™ shock product or use HTH™ Green to Blue Advanced for a severe bloom. If the water is still hazy after the algae treatment, wait 4–12 hours after shock and add HTH™ Clarifier Advanced as directed.
