Hey guys
This is Jay with PoguePoolSpa.com
today I'm going to be talking to you about total alkalinity a basic guide to pool
alkalinity
some information to consider
total alkalinity is the ability of water to resist changes in ph
Total Alkalinity is a measure of the dissolved bicarbonate present in your porter
total alkalinity is measured in parts per million or ppm
if your alkalinity is high, your ph is most likely high as well
this is because they're related
Generally try to keep your alkalinity between eighty and one hundred and
thirty ppm
This is the level that Pool and Spa Professionals use as acceptable
some useful info
as alkalinity increases ph tense arrives
when alkalinity is adjusted to a range eighty to one thirty ppm
it maximizes the chances that pH will hold in the acceptable range
of seven point two to seven point eight
different types of chlorine will have different effects alkalinity levels
so if you test your water and notice an abnormality after adding chlorine or
sanitizer
contact a service professional for more information before just adjusting further
it will save you time and money in the long run
decreasing total alkalinity is a long process that could take weeks or sometimes
months to get under control
one of the effects of total alkalinity
if you're alkalinity is too low
then your plaster on your pool can start etching and staining
you can get metal corrosion, and your ph can start moving around erratically
if your alkalinity is too high
then you will frequently need to add acid to the water order to lower the pH to the desired
range
you'll have cloudy water and your pool can start scaling
always try to keep your water chemistry balanced
this will save you money the long run
adjusting alkalinity levels
when balancing water always test your water first
then consult a service professional for advice
when adjusting chemical levels always adjust the alkalinity first it'll save you
trouble and lots of money
to raise your alkalinity levels add baking soda to your pool
wait a few hours and then retest
Then add more as needed
To lower your alkalinity levels add a pH reducer to the water
Since a pH sample of 7.2 or less almost always indicates
alkalinity of less than seventy
there needs to be increase of alkalinity of at least the sixty ppm
to bring alkalinity into the correct range
