The alkalinity in my in ground pool (25K gallons) is very high. It takes 20 drops in the tester to produce clear test. I've already bought a new tester. My ph is normal. How do I lower the alkalinity without also lowering the PH too much? I have to add acid but won't that also lower th PH too much?
Answer
You can lower the alkalinity with muriatic acid. 1.3 pints per 10,000 gallons will lower it by 10ppm. 3.25 pints in your pool will lower it by 10ppm. To get to the level you need of approximately 100-120 you will need to use 26 pints of muriatic acid to reduce it by 80ppm or 3.25 gallons of liquid muriatic acid.
You are testing the TA and getting 200ppm for your inground pool right? Make sure you walk a perimeter around the pool while pouring this in and wear proper safety equipment (eye protection and gloves) as muriatic acid is a diluted form of hydrochloric acid. Make sure you turn off any automatic chlorinators or remove chlorine pucks/sticks from the pool and NEVER let muriatic acid come into direct contact with chlorine products. Once in the water it will play safe but outside of water it will create chlorine gas which will kill a human in a matter of minutes.
You can get muriatic acid from the pool store or a local hardware store (sold as a cleaning agent).

Anyone here know why water makes a stain in the bathtub?
B
My water makes a pink slimy stain when it pools up somewhere for a day or two. It stains the drain and the toilet. Also, when you leave a few drops of water in the bathtub, a pink stain appears. Its gross, it comes off with soap. But I wonder why it does that?
Answer
Check this out....it is off the internet:
What White Water Mold is & what it looks like:
a naturally occurring bacterium (of the newly formed genus Methylobacterium) (this is NOT a form of Algae, it is animal not vegetable)
Pink-pigmented, forms a heavy, protective slime coating providing the organism with an unusually high level of protection, methanol consuming, oftentimes found WITH White Water Mold
that is very resilient against halogen-based (chlorine, bromine) as well as non-halogen sanitizers or germicides can remain a contaminant even after treatment
this is NOT a biguanide problem ONLY
bacterium has an affinity for the matrix that exists on the surface of PVC plastics; it will attach itself to & inside of the matrix, allowing it to re-contaminate long after it appears that it has been destroyed (includes pool toys, floats, ladders, steps, fountains, automatic pool cleaner parts, skimmer baskets, weirs, directional fittings, garden hoses, etc.)
small quantities can lead to a re-establishment of the problem
caused by improper water & pool maintenance, environment, poor circulation
prefers areas that are "dark" (not exposed to direct sunlight) & with "slow moving" water
** in another industry, medical technology, this bacterium occurs regularly in laboratory tubing
White Water Mold & Pink Slime are NOT CAUSED BY USING BIGUANIDES (Soft Swim, Baquacil, Polyclear, etc.)!
It is an environmental issue.
Prevention:
Prevention of "white water mold" & "pink slime" is preferred over treatment. Follow these steps to help prevent white water mold:
1. Physically brush & clean ALL Spa surfaces weekly, including steps, jet recesses, & behind pillows
2. Expose ALL pool surfaces to as much sunlight as possible (sunlight & UV are natural
oxidizers)
3. Remove the lid from the skimmer to allow sunlight into the basket for several hours each
day ** INGROUND POOLS MUST USE EXTREME CAUTION in doing this in order to avoid
a person falling into or otherwise injuring themselves due to an open skimmer.
4. Regularly add oxidizing chemicals into the skimmer to purge & clean the filtration lines of
any bio-film*
5. When adding make-up water from the garden hose, allow the water to run for 2 to 3
minutes before putting the hose into the pool.
6. Regularly clean spa & hot tub toys & floats (use BioGuard® Stow Away)
7. Regularly clean pool solar blanket (use BioGuard® Stow Away)
8. Chemically clean pool filter every 4 to 6 weeks (use SpaGuard® Filter Cleaner or SoftSoak® Filter Cleaner)
9. Add regular Maintenance dosages of "Shock" (SpaGuard® Spa Shock, SpaGuard® Enhanced Shock, SpaGuard® Chlorinating Concentrate, SpaGuard® Brominating Concentrate or SoftSoak® Shock) every week as prescribed
10. Run the filter a minimum of 6 hours daily to prevent "dead spots" in the pool
11. Remember to clean & rinse the brushes, hoses & vacuums that you use to clean the spa
12. Leave as much of your spa equipment exposed to the sun
13. Keep the water balanced at all times. Recheck after heavy usage or rain or large "top-offs" of new water. Water balance refers to Free Available Sanitizer level, pH, Total Alkalinity, Calcium Hardness.
