Chlorine must be constantly replenished. High levels can cause pH to rise. High levels can cause calcium scaling. Borate - An optional enhancement. Phosphate - Doesn't matter, despite pool store claims otherwise. All nine are described in more detail below.

It is important that you do not allow FC to get too low, or you run the risk of getting algae. If FC gets down to zero, or you have algae, the pool is not safe to swim in. Free chlorine shows the level of disinfecting chlorine available active plus reserve to keep your pool sanitary. FC should be tested, and chlorine added daily.

If you have an automatic feeder or SWG, you can test it every couple of days. FC is consumed by sunlight, and by breaking down organic material in your pool. Recommended ways to raise FC include: CC - Combined Chlorine Combined chlorine is an intermediate breakdown product created in the process of sanitizing the pool.

CC causes the "chlorine" smell many people associate with chlorine pools.

If CC is above 0. CC indicates that there is something in the water that the FC is in the process of breaking down. In an outdoor pool, CC will normally stay at or near zero as long as you maintain an appropriate FC level and the pool gets some direct sunlight.

There is a special reagent you can get to neutralize the potassium monopersulfate so you can get a true CC reading.

PH should be tested daily at first.

Once you gain experience with your pool, less frequent monitoring may be appropriate, depending on your pool's typical rate of PH change. A PH level of 7.

PH levels below 7. High PH can lead to calcium scaling. Many pools will drift up towards higher PH over time. This is particularly true for fresh plaster particularly in the first month and continuing for perhaps a year or when TA is high and the water is being aerated because of a spa, waterfall, fountain, SWG, rain, kids splashing in the pool, etc.

For lowering PH use either muriatic acid preferred or dry acid. To raise PH use borax or soda ash. Buffering means you need to use a larger quantity of a chemical to change the PH. At low TA levels, the PH tends to swing around wildly.

At high TA levels, the PH tends to drift up. You can raise TA with baking soda. It is often best to make large TA adjustments in a couple of steps, testing the water after each one, as adding large quantities of baking soda can raise the PH a little and you don't want the PH going out of range.

CH - Calcium Hardness Calcium hardness indicates the amount of calcium in the water. Over time, water with low calcium levels will tend to dissolve calcium out of plaster, pebble, tile, stone, concrete, and to some extent fiberglass surfaces. You can prevent this from happening by keeping the water saturated with calcium.

In a vinyl liner pool there is no need for calcium, though high levels can still cause problems.Swimming Pool Store: Free Shipping on orders over $45 at leslutinsduphoenix.com - Your Online Swimming Pool Store Store!
