Stains And Scale; Trashed Pool Treatment - Intec CA10 Instruction Manual

H. When you notice your pool water is discolored (before you do anything else), check and
treat your pH if high. Then wait until the next day because your water may clear. This
is caused by the lower pH reabsorbing whatever caused the discoloration.
I. Get the water from the pool for testing about 12 inches below the surface.
J. Algae should never be allowed to infest the pool. This may happen when you go on
vacation and the pool water has not been properly tested and treated. Once the pool
water is properly tested and treated, the copper will kill the algae but will not make it
disappear. Start an oxidation program (See Section 6.2) of one quart of Bleach or
Hydrogen Peroxide for every 8,000 gallons a day until the algae is no longer visible.
Even though the algae are dead, they may still retain their color and stickiness for several
days.
This was discussed earlier in Section 5.1 (under pH). In pools, stains and scale are either
caused by low pH or high pH.
First test and treat your pH, and then wait one day. If the stain or scale still exists then
use a product called Stain Tamer to remove the stain or scale. Be careful not to use a
product called Metal Out. Metal Out, and others like it, can bind up the copper ions in
your swimming pool/spa, making them ineffective.
If a stain appears on the steps or swimout, you may use the muriatic acid (the same as
you use to lower the pH) to remove it.
SECTION 9.0 TRASHED POOL TREATMENT
A. Remove all trash from pool. Do not leave a single leaf!
B. Clean skimmer baskets, and pump weir basket.
C. Put filter on re-circulate and add proper amount of Drop-Out or Heavy Flock. (Follow
Drop-Out instructions especially regarding the pH)
pump for 2 hours then cut pump off.
D. 24 hours later, hand vacuum slowly to remove waste. Wait one more day as pool water
may drop out additional waste during this time.
E. You may have to add water to your pool when water goes below the skimmer. If this
happens, then you MUST:
