Quick Answer: Should I Adjust PH Or Alkalinity First?

How do I balance 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..

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. “

Will Shocking pool lower pH?

Shocking the pool will lower the pH, whether you use chlorine-based shock (calcium hypochlorite), or the non-chlorine kind (potassium peroxymonosulfate).

How long does it take for pH down to work in pool?

Answer: If it’s small pH adjustment then it is ok to swim after 1 hour of pool circulation. If a large quantity of acid is being added, wait 24 hours then re-test the pH to make sure the water is not too acidic.

Does alkalinity affect chlorine level?

If your pool water is too alkaline, it can cause scaling on your pool’s surface and plumbing equipment, and can cloud the pool water. In addition, both high acidity and high alkalinity will alter the effectiveness of your chlorine, which will clearly disrupt your pool’s disinfecting processes.

Will pH down lower alkalinity?

In other words, if you lower a pH of 8.3 to the recommended level using muriatic acid, the total alkalinity will also reduce but will still remain on the higher side. Likewise, if you lower alkalinity to the recommended level (e.g., from 300 ppm to 80 ppm), the pH level drops way below the recommended level.

Does pH plus increase alkalinity?

If your PH is low, you need to add a PH Plus to increase these levels. … PH Plus will increase your Alkalinity level slightly too so keep an eye on this as remember Total Alkalinity is the buffer to allow your PH to be set.

Will alkalinity decrease on its own?

One of the most important things to remember about high alkalinity is, if you can afford to wait, it will decrease over time on its own. … That’s what alkalinity does. It helps prevent pH from changing too much, too fast. When you lower alkalinity, you’ll also be lowering pH.

Does pool shock increase pH?

Chlorine based pool shock (Calcium Hypochlorite) has a high pH, and will naturally raise the pH level of your swimming pool water, in addition to changing your chlorine level. Chlorine free shock has a neutral pH, and will not affect any of your pool chemical levels.

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.
