Only way to reliably lower CYA is to drain and refill the pool.
Trying to Get Rid of the Pool Cleaning Blues with Robotic Cleaner
- Thread starter thomas kleaton
- Start date
Going back to some earlier topics in this thread:
Besides leaves and algae, you had floc clumps from the initial Green to Clean. Alum will produce the same.
For all of those floc agents, one must carefully vacuum it out to waste. Any leaf raking, netting, roboting, or brushing will break up the clumps of floc, and resuspend them in the pool water, making it cloudy. Some kinds of floc will then not reclump nor resettle, and the water stays cloudy. Some will, but only partially.
Meanwhile, depending on kind, that that gets to the filter has a high risk of permanently plugging the sand in the filter. Even if it doesn't clog the filter, it can take a LONG time to get the suspended material out of the water.
It appears you have dodged most of the bad side effects, now. Backwash that filter. Better would be to do a deep clean. Deep Clean a Sand Filter
I now return you back to the current topic, to continue on with the recommendations by others....

This is pool after I vacuumed it thoroughly. I haven't used pool robot yet, but will likely use it this weekend sometime.
I can't understand why I don't have an algae bloom if my CYA is at 80 ppm, but I don't think the test lied. I kept adding drops of tested pool water
to the vial in TF-Pro kit until the black dot at bottom vanished and level in vial was at 80 mark. I did test twice with separate samples of pool water.
Water is still as clear as glass.

Read these instructions for the most accurate result (print them out...having them helps):

I did this test in the kitchen, staring directly down into the tube like you'd stare down a microscope. I'll try the test again tomorrow, doing it exactly as specified in article, with sun at my back.Read these instructions for the most accurate result (print them out...having them helps):

Maybe I'm wrong, but I would think a newish HTH test strip read at 20 seconds after dipping into water would halfway agree with the TF kit test results. Strip showed CYA at 40.
Only take a flash of a glance. If you stare your brain lies to you. Wanna see ? Look at your nose. Yeah. You're going to see it for the next half hour now. Sorry about that

Lighting makes a huge difference. Print out the instructions. Sun at your back, hold at your waist in the shadow of your body and glance.

R-7065 CYA Standard 50ppm (2oz)
I changed the filter sand last July 4, using #20 silica sand instead of play sand I've seen people use. I had to use my old Craftsman wet/dry vac to remove it, and it was a job.
Good news! I retried the CYA test twice again the way it's outlined in the article, with the sun at my back, glancing at it, and got better results. The first
time I tested, I filled it to 50 mark on vial and could still see it. I then filled it to the 40 mark and dot disappeared.
Second time, I could barely see dot at 40, so filled it to halfway between 40 and 30. Dot disappeared. I rinsed utensils with tap water before second test. so that may have interfered, but I figure CYA is somewhere between 40 and 50 so will use 50 as determining factor in SLAM.

Crazy, right ?
Don't bother with redoing the test from scratch next time. Just pour the sample mix back and forth as many times as you need to get best of 3.... 4 of 7..... 5 of HOLY COW WE ALL HATE THIS TEST.
