Shiner’s Citric Stain Remover is a weak acid that occurs naturally in citrus fruits. This acid is more environmentally friendly than most and acts as a cleaning agent for swimming pools. Citric acid removes the stained area of a pool when applied by eating away the top layer of the pool’s surface. It does not harm a pool to have such a thin layer removed, it simply clears away the stain. Citric acid is a gentler stain remover than muriatic acid, another form of acid used to remove stains and resurface swimming pool interiors.

3 Inch Chlorine Tabs

50lb, 55lb, 100lb


  • Ideal for use with floaters, feeders or skimmersbromine-tabs
  • Stabilized to help prevent UV degradation from sun light

Chlorine tablets are one of the key chemicals to maintaining your pool water, and 3 inch chlorine tablets are the most popular among long-time pool owners. They are thicker than other pool chlorine tablets, allowing them to dissolve slower and protect your pool water for longer. They are also the ideal size for floaters, skimmers, or automatic feeders and are individually wrapped for your convenience. Tablets contain powerful 90% available stabilized chlorine, 99% Trichlor-S-Triazinetrione. Dosage: approximately 1-2 tabs per 10,000 gallons of water per week.

Liquid Chlorine (Sodium Hypochlorite 12.5%)

  • After heavy swimmer load
  • After strong rains and winds
  • During periods of extreme sun
  • Unpleasant odors
  • Signs of algae growth appear
  • Water appears dull, hazy, or cloudy

Shock treating your pool weekly is important because it protects you and your family from bacteria and organic contaminants. Super chlorination or shock treating removes chloramines, which cause eye irritation and “chlorine” odors from the pool water by adding free available chlorine (FAC).

We suggest shocking at the same time and day each week. Sundown is the best time to shock your pool because the chlorine can work without fighting the sun’s UV rays. Shocking after sundown also gives chlorine more time to restore water clarity. In some cases, you may need to shock more than once a week.

  • Dry acid or Sodium bisulfate in granular form4881-a-sq_1
  • Safer than muriatic acid
  • Quickly dissolves
  • Keeps pH levels balanced
  • Prevents excess calcium buildup

Dry Acid (Sodium bisulfate) is a granular form of acid and is used to lower the pH, to maintain balanced water and total alkalinity in pools and spas. This form of acid is safer and less caustic than muriatic acid and will not spill or splash so it is safer and easier to use. This product is easier to store but it also must be used with care.










  • 4881-a-sq_1100% cyanuric acid
  • Protects chlorine from UV Rays
  • Reduces the cost of chlorine

The sun’s UV rays can destroy 90 percent of the chlorine added to the pool water in just 2 hours. Shiner’s Conditioner extends the life of chlorine 8-10 times longer by protecting chlorine from this UV loss. Shiner’s Conditioner allows the chlorine to stay in the water longer, reducing the cost of chlorination.

When people use spas, they leave undesirable compounds like body oil, perspiration and cosmetics that can irritate skin, burn eyes and create odors. Oxidizing, also known as shocking the water, removes these compounds and restores water clarity and comfort. An oxidizer should be used weekly in most residential spas and more frequently in heavily-used or commercial spas







Aqua Ammonia Industrial Grade

1 gl,2.5gl,5gl,15gl,55gl and 275-330 tote







  • Specialty chemical

Ammonia solution, also known as ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or simply ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH3(aq). Although the name ammonium hydroxide suggests an alkali with composition [NH4+][OH−], it is actually impossible to isolate samples of NH4OH, as these ions do not comprise a significant fraction of the total amount of ammonia except in extremely dilute solutions.

Muriatic Acid

  • Safer formula with less fumes
  • With no mixing our products is ready-to-use
  • Lowers pool water pH

Muriatic Acid is a strong, corrosive, inorganic acid (HCl), manufactured by absorbing hydrogen chloride in water. It is one of the most corrosive of acids, and is particularly destructive to cellulose, breaking the cellulose chain into even smaller units, resulting ultimately in its complete hydrolysis. It is the same chemical as Hydrochloric Acid.

  • Stops odors by preventing the formation of hydrogen sulfide

  • Reduces collection system and plant corrosion

  • Provides a highly efficient non-carbonate buffered (<10 pH) source of sustainable alkalinity and pH for plant nitrification and BNR processes

  • Enhances plant clarification and dewatering

THIOGUARD TST (Total System Treatment) is a non-hazardous, non-pharmeceutical alkaline slurry for use in the treatment of municipal water and wastewater. Magnesium hydroxide is most recognized as “milk of magnesia,” a safe treatment for acid stomach. The technology is simple. Addition of relatively small amounts of THIOGUARD added upstream directly to municipal wastewater collections systems and/or wastewater treatment plants:
