I'm visiting my wife's aunt in Massachusetts.
They have an 11,500 gallon, vinyl liner AGP with a sand filter.
They use trichor, and have been shocking with cal hypo. Their water is greenish and cloudy, but you can still see the bottom drain.
These are the pool store test results:
Saturation index: -2 (Ideal -.3 - +.3)
TDS: 1400 (Ideal <2500)
CYA: 80 (Ideal 30 - 200)
Total Chlorine: 10 (Ideal 1 - 3)
Free Chlorine: 10 (Ideal 1 - 3)
pH: 6.4 (Ideal 7.4 - 7.6)
Total Alkalinity: 33
Adjusted Total Alkalinity: 9 (Ideal 125 - 150)
Total Hardness: 334 (Ideal 175 - 225)
Optimizer+: 47 (Ideal 30 - 35)
EXCEEDS RECOMMENDED LEVEL
Use Chem Out ( http://www.parpools.com/page/poolcare/B ... m-Out.html )
Your chlorine residual is too high. Lab tests used to measure chlorine residuals are inaccurate above 5 ppm. Other test results, such as pH and total alkalinity may also be affected. Use Chem Out according to label instructions to lower the residual. Circulate 8 - 12 hours, then retest the sanitizer. Dilute the sample with distilled water if necessary to acquire a reading. If it is still above 8 ppm, reapply. Do not swim until the chlorine residual returns to 1 - 3 ppm. Proceed to the next step.
Saturation Index
Your Saturation index is low. This indicates that your total alkalinity, pH, and/or total hardness ared out of balance. Low Saturation index can cause corrosion of equipment, surface damage, and eye and skin irritation. To properly balance the water, follow the instructions below.
Total Alkalinity
Add 21.5 pounds of Balance Pak 100 ( http://www.bioguard.com/Our_Products/Ba ... %C2%AE_100 )
Your total alkalinity is low. Low total alkalinity can cause equipment corrosion, surface damage and swimmer discomfort. Divide the Balance Pak 100 dosage into thirds, predissolve and apply each third 4 - 6 hours apart to prevent staining. Add directly to the pool with the pump running. Wait 2 hours after the final application, then proceed to the next step. Wait 15 - 30 minutes after applying to swim.
pH
Add 1.25 pounds of Balance Pak 200 ( http://www.bioguard.com/Our_Products/Ba ... %C2%AE_200 )
Your pH is too low. Low pH can cause equipment corrosion, surface damage, and can irritate swimmer's eyes and skin. Add Balance Pak 200 directly to the pool with pump running. Brush up any undissolved product. Wait 15 minutes, then proceed to the next step. Do not swim for 15 - 30 minutes after applying.
Total Hardness
Add 1.25 quarts of Scale Inhibitor
Your total hardness and/or saturation index are high. Add Scale Inhibitor directly to the pool with the pump running. When the total hardness and saturation index are too great, the water can cloud and scale may form. Follow the label instructions for the maintenance dosage. After adding scale inhibitor, wait 15 minutes, then proceed to the next step. Do not swim for 15 minutes.
-------------------------------------------------------------
So, they instructed them to add the chem out first, and then tonight add the alkalinity increaser.
Then, in the morning, add the pH up.
---------------------------------------------------------------------------------------
To clarify, I'm a BBB user, and have ordered a test kit as a gift for them. I'm here until thursday, so I'm hoping to be able to get them on the right track.
So, even though the pool store says the pH is too low (which it more than likely is, since they've been using trichlor), they tell them to use the Chem Out (what the heck is this stuff anyway?), even though it says "Adjust pH to 7.5 -8.0 for best results.": http://www.parpools.com/page/poolcare/B ... m-Out.html
Thoughts about using that much alkalinity increaser? Scale inhibitor?
My wife's Aunt and uncle trust this pool store, so I'm treading lightly to try to educate them and not offend....but I'm also hoping to be able to solve this problem for them before I leave, and I'm scared that if he follow all these recommendations, it will be impossible for me to do so.
