Mistake Using the Clorox App

Mates,

New first time pool owner. Saw the Clorox strips in Walmart and downloaded the app. I used the App for a couple of week or so going by the "scan" feature with my phone. Then, I decided instead of using the scan feature to scan one strip and then do another strip and analyze the colors on my own. Well, I discovered the scan readings were way off. This was after I added a bunch of stabilizer. The pool calculator said I needed to drain 80% of my water. I'm not really up for that and my daughter is having friends over tomorrow. I ran my backwash and filled my pool a few inches...I live in southern Louisiana and have to fill the pool a few times a week with evaporation. The stabilizer reading came down a little this morning. Still real high.

The water so far looks okay. FC and PH were at the low range, and I added 80 ish ounces of 6% bleach this morning. My game plan is to try and see if the Stabilizer will drop naturally with our typical summer rainfall and me having to add water a couple times a week.

Should I shut down my in line chlorinator with trichlor tablets completely in the meantime?

I'd love to hear your experienced thoughts and any advice whatsoever. Thanks.
 
Precise water testing is the key to pool maintenance and why only the TF-100 or the K-2006C test kits are recommended. Without good test results everything you add to your water is a guess and very often leads to more problems and costing more money. Get yourself a proper test kit and learn to use it is recommendation #1.

That said, chlorinating your water with thichlor tabs that contain stabilizer will eventually raise your stabilizer, CYA to the point that you will need to drain your pool as it has a direct relationship to your free chlorine level and the ability to sanitize your pool properly. Move away from the solid forms of chlorine and use only liquid Sodium Hypochlorite with no additives, very important, no additives.

Your game plan may work but without proper testing we have no idea how high your CYA actually is and how much water needs to be removed to lower your CYA to a manageable level. There is a CYA to FC ratio you should review......Pool School - Chlorine / CYA Chart

Also take some time to study Pool School and learn to use the Pool Math calculator but to start you need to invest in a proper test kit and learn to test your pool water.
 
Yes, bleach, liquid chlorine and there are different concentrations ranging from 6% to 12%+ so be sure the check what is available. Be aware some bleach products contain additives i.e. "chlormax tech", fragrance, splashless so read labels and avoid those additives. Also look for a date code as time and heat will degrade the % active. There are some good calculators that compare the cost of different % products based on actual $ per unit of chlorine. Look around on this site for the best value in your area, there are a couple of active threads. I get 10% liquid at Home Depot that is reasonably priced and not over 2 months old.
