HTH Sanitizers

Your pool stays clean and clear with HTH sanitizer products, designed to effectively guard against bacteria, algae and other organisms. We offer two types of chlorine-based sanitizers: stabilized and unstabilized.

The HTH Super Benefit

These convenient and easy to use HTH super 3” chlorinating tablets are formulated to protect against chlorine loss in direct sunlight and they also contain built-in algae protection and clarifier. They are designed to dissolve slowly to provide a steady source of available chlorine.

Application Instructions

Place this product in a feeder, floater or skimmer designed for this product. Use in a new feeder or any device which has previously contained only this product, trichloro-s-triazinetrione. Do Not use in feeders that have been used with other water treatment products. Do Not add other chemicals to the feeder while this product is present. If placed in the skimmer, run the pump a minimum of eight hours daily. Do Not throw tablets directly into pool or pool surface damage could occur.

Re-entry into treated swimming pools is prohibited above levels of 4 ppm chlorine due to risk of bodily injury.

Test Your Water

How often you should test and balance your pool can vary based on how often you use it and a number of other variables, but it’s important to remember that, for chlorine and pH, you should usually test your pool two to three times a week. That may sound like a lot, but water balance is vital for your pool’s health and the health of the people who swim in it. When your pool is out of balance, your sanitizers can be less effective, the water can cause irritation to the skin and eyes, and if the water gets imbalanced enough, it can even damage the pool’s surfaces, structure, or equipment.

Shock Weekly

In ideal circumstances, shocking your pool just once a week will keep it looking clean and clear, but any heavy rainfall, signs of algae, use by lots of swimmers, or periods of very sunny weather can deplete free chlorine levels, which means an extra dose of HTH Shock is needed.Sundown is optimum time to shock your pool because the chlorine can work without fighting the sun's ultraviolet rays and has more time to restore water clarity.

Overstabilization: What is it?

While small levels of CYA (20 – 40 ppm) do serve a purpose in protecting chlorine from sunlight degradation, too much can cause problems. Over-stabilization (> 90 ppm) is the buildup of cyanuric acid (CYA) in swimming pool water resulting from the use of stabilized sanitizers and stabilized shock products. It significantly decreases the effectiveness of chlorine in killing germs, bacteria and algae.

HTH Pool Care offers sanitizer and shock products that are non-stabilized. These are calcium hypochlorite (cal-hypo) products, do not contain stabilizer and will not cause over-stabilization. Symptoms of overstabilization:

Green water.

High chlorine reading with algae.

Adding chlorine does not get rid of algae What is the Solution to Overstabilization? If the CYA level is > 90ppm, adjust this by partially draining some water from the pool, refilling with fresh water, balancing the water and switching to HTH non-stabilized sanitizers and shocks.
