How much of this alkalinity increaser or sodium bicarbonate can I add to my pool at once?

A  Answered on 9/2/2014 by InyoPools Product Specialist Patrick P.

You should only add up to 10 lbs. per 10,000 gallons of pool water of our alkalinity increaser per treatment if needed. Also we advise to mix with pool water first and not to add any other chemicals in conjunction with it.  Follow the printed instructions if unsure and leave the pool running for 24 hrs after ward for proper circulation of the chemical.

My test kit only check for chlorine and pH. What does the alkalinity do?

A  Answered on 12/20/2012 by InyoPools Product Specialist Patrick P.

Total Alkalinity is a measure of the "buffering capacity" of water, or its ability to resist a change in pH. Low Total Alkalinity can cause: etching of pool plaster, corrosion of metal parts, staining of the pool surfaces, etc. High Total Alkalinity can cause cloudy water, burning of eyes, chlorine being ineffective, etc.

What can we use in our salt water pool to lower the alkalinity?

A  Answered on 12/19/2012 by InyoPools Product Specialist Patrick P.

To decrease the alkalinity level in you pool, you can use dry acid, muriatic acid or simply partially drain and refill the pool. Just use caution as the acid will bring down the pH as well.

I just purchased a house with a pool. I tested the pool water and according to the chart, I need to adjust the pH, alkalinity, chlorine and calcium hardness levels. How much of each do I need to add to my pool?

A  Answered on 10/18/2012 by InyoPools Product Specialist Patrick P.

The amounts of each chemical you will need to add will depend on the volume of the swimming pool (gallons) and the actual chemical levels. You can use our How To Guide for reference.

Spread desirable amount around the pool with the pump running, and make sure you do not mix with other chemicals at the same time.
