What Should Be Adjusted First Alkalinity Or PH?

How long after adding pH up can you add shock?

8) How long after adding chemicals can I swim.

Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals.

Wait about 20 minutes, and you are free to swim.

We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool..

How do I adjust the pH and alkalinity in my pool?

A rule of thumb is 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool’s pH tested below 7.2, add 3-4 pounds of baking soda. If you’re new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.

How do you lower the alkalinity of a good pH?

To lower pH and total alkalinity, use a strong acid such as muriatic acid, sulfuric acid, or sodium bisulfate, all of which lower both pH and TA, but at different rates. You need to use an accurate water test kit that can give you correct readings.

Can I add pH up and alkalinity at the same time?

To raise pH and Alkalinity at the same time, start with Alkalinity, and add enough Increaser to raise Alkalinity to 100 ppm. Add 1 lb Alkalinity Increaser per 10,000 gals, to raise Alkalinity 10 ppm. The pool pH level may rise and follow, without added pH Increaser.

Is alkalinity increaser the same as baking soda?

The industry standard has always been to use sodium bicarbonate (baking soda) to raise total alkalinity and sodium carbonate (soda ash) to raise pH — the exception being if both total alkalinity and pH are low. … Sixteen ounces of sodium bicarbonate will raise the Total alkalinity of 10,000 gallons of water by 7.14 ppm.

Is it safe to swim with low alkalinity?

Your swimming pool can come to immeasurable harm if it contains water with low alkalinity. You risk your pool walls becoming etched, delaminated, or cracked. … Asides its effects on your pool, a low alkalinity swimming pool is unsafe for swimmers as the acidic water can cause nasal, eye, and skin irritations.

Can you use soda ash to raise alkalinity?

Note that soda ash does also raise alkalinity along with pH. That six ounces of soda ash will raise your alkalinity by about 5 ppm, so only use soda ash if you want to raise alkalinity and pH.

Can I add shock and soda ash at same time?

Test strips are next to useless. The CYA (stabilizer/conditioner) reading is probably wrong. If the pH were low, you do not add sodium bicarbonate to raise it — that’s for raising the TA.

Can I use pH up and shock at the same time?

Using liquid chlorine raises the pH of the water. Liquid chlorine does not raise pH. … Chlorine shock + Sequester Agent: Chlorine shock will also disrupt stain & scale chemicals, aka chelators or sequestering agents, if added at the same time.

What’s more important pH or alkalinity?

Water pH measures the amount of hydrogen (acid ions) in the water, whereas water alkalinity is a measure of the carbonate and bicarbonate levels in water. … Regardless of the starting pH, the higher the alkalinity of the water source, the more acid is required to reduce pH to 5.0.

How do you lower alkalinity without lowering pH?

You’ll actually see the bubbles forming around where the “slug” is added – that is, the bicarb burning off and bubbling up. If you wish to lower the pH without also reducing the Total Alkalinity, simply pour the dose of muriatic acid about the pool. “

Does high chlorine affect alkalinity?

When using high-pH chlorines like salt chlorine generators, liquid chlorine or cal hypo, you will need less alkalinity, like 60-80 ppm. For low pH chlorines like Trichlor, 100-120 ppm might be a better range for you.

How do I adjust the alkalinity in my pool?

To raise the TA level (and not the pH too), you add Baking Soda (Sodium Bicarbonate). Baking Soda will also raise the pH of the pool water slightly. If you need to raise both the pH and TA, then use Soda Ash until the pH comes to the proper level, then use Baking Soda to make further adjustments to the TA if needed.
