What should the pH be in a fiberglass pool?
7.4 to 7.6
Proper pH maintenance is extremely important as it is responsible for the correct bacterial action of the chlorine, swimmer comfort and prevents deterioration of the equipment and the pool itself. A proper pH reading is 7.4 to 7.6. Ideally, your pool should be maintained at the higher level of 7.6.
What pH is too high for pool?
7.8 pH
When the pH level in your pool exceeds 7.8 pH, your water is considered to have high pH. This means that your water is now too soft and there can be consequences. A high pH level can be caused by several factors, the main culprits being additional chlorine stabilizers and sudden increases in temperature.
Does chlorine damage fiberglass?
Re: Will bleach for chlorine harm a fiberglass pool or my pump? Nope, no worries. Bleach is sodium hypochlorite as is liquid chlorine. In the water it’s all the same chlorine – the only difference is what else goes into the water with the chlorine.
Can you use liquid chlorine in a fiberglass pool?
So adding certain chemicals can dramatically affect the pH in your Fiberglass pool. A note about Liquid Chlorine – even though it has a higher pH than Cal-hypo shock, it is better to use since it has such a low chlorine level 12-15% and is quick dissolving.
What happens if you drain a fiberglass pool?
If your water level is too low, it could cause your pump to lose prime and incur damage. Alternately, too high a water level reduces your skimmer’s effectiveness. Never drain your fiberglass pool without professional assistance. Due to ground pressure, most fiberglass pools can experience damage when drained without taking proper measures.
Is it safe to swim with a pH of 8.0?
Starting sixty years ago, pool industry chemists (incorrectly) suggested that a pH of 8.0 and higher makes chlorine ineffective and not safe to swim in. But the truth is that just 1 ppm of chlorine in pool water with a pH of 8.5 and zero CYA contains more active chlorine (HOCl) than needed to kill algae.
What happens when the pH of the pool is too high?
One of the most frequent problems is when a pool’s pH gets too high. The pH is a measure of the water’s balance between acidity and alkalinity. If the pH isn’t properly balanced, problems can occur. Water pH ranges from 1 to 14. Lower numbers are more acidic, and higher numbers are more alkaline.
What should the water balance be in a fiberglass pool?
Water Balance is Important: Daily testing can help maintain the optimal water balance. It is best to have a pH balance at 7.2-7.4 and the total alkalinity needs to be at 80-100 parts per million. Maintain your chlorine at or above 1 ppm and the calcium hardness at 200 to 400 ppm.

What should the pH be in a pool?
Lower numbers are more acidic, and higher numbers are more alkaline. Proper pool pH is right in the middle — pool pros recommend that pH be between 7.3 and 7.6 for optimum performance and cleanest water. If the pH gets higher than 7.8, the water is becoming too alkaline.
Are there any problems with a fiberglass pool?
Fiberglass pools are the most durable and damage resistant Concrete pools look beautiful, and they can take a myriad of shapes. But they’re susceptible to one very pesky problem: cracks. Eventually, the plaster on the walls of a concrete pool will begin to crack from years of chemical exposure, ground movement, and general wear and tear.
How often do fiberglass swimming pools need to be relastered?
Well, a lot of those same pools are still being used today. Talk about durability. Of course, despite their toughness, fiberglass pools do require some maintenance. While they don’t have to replastered or re-lined, they do need a gel coating replacement every 15 years.
