Stains And Scale; Trashed Pool Treatment - Intec CV40 Instruction Manual

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. (Follow Drop-Out
instructions especially regarding the pH) With filter on re-circulate, run pump for 2
hours then cut pump off.
D. 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:
1. Readjust your pH,
2. Test and adjust copper,
3. Test total alkalinity, and
4. Test calcium hardness
F. Add Stain Tamer. Please note - Use only products called Drop-Out and Stain-Tamer.
Do not substitute. Results will vary according to the pool condition.
