New Owner - High Combined Chlorine and TA - Need Help Please

You can use your pool vac. Just be careful to not put too much suction on the light niche.

You can test your FC after you finish cleaning it out. Then raise back to SLAM. Be sure to leave the light out on the deck so the pool water can freely get into the niche.

Glad you found what was delaying this!
 
That was fine. Sorry for the delay in response. We had a storm last night and lost power for several hours. Rain - an oddity here in Laughlin!!
 
Hope all is ok by you. Today’s looking good. FC only declined about 2ppm overnight. Have added chlorine sparingly this morning. Will monitor all day.
My wife would like to send you a gift card in appreciation for all your help and patience. If that’s allowed, pls feel free to send me an address by private message if you prefer.
 
Will do. Since we have an auto pool cover and pool is not affected by rain, do you recommend a robot for our pool size? Perhaps if I get rid of the pool guy (I think cleaning is only thing he did)??

if yes, can you recommend a bot?
thank you.
 
Robots make the cleaning easy. They do not climb onto shallow tanning ledges nor do steps real well. So they have to be brushed or just move the water around when you swim. Mine is a basic robot. No bluetooth, etc. Works great for our small pool. The Maytronic (Dolphin) line is very popular here on the forum. A robot is one thing you might want to consider buying from a pool store. It gets you a better warranty most times and you have a local business to help with repairs, etc.

You do need to monitor your chemistry even with a SWCG. pH is the one that might move the most. So I would bet the pool person added acid every once in a while. Be sure to use muriatic acid. Not dry acid. The dry acid adds sulfates to your water which can damage your SWCG.

I would take it back to SLAM level FC and run the pump today at your low rate. I suspect you will pass the OCLT tonight. Be sure to take cover off for a few hours this afternoon.
 
Correct. Use the amount of liquid chlorine/bleach PoolMath says. Test in a few hours and add more as necessary.
 
60 CYA is fine. Use 24ppm SLAM level.

Your pool is covered most of the time so a lower end CYA is fine with your SWCG.
 
I suggest you go with the plan we had before.

To recap ---

To start, run your pump 12 hours per day with your SWCG setting at 100%. That will add about 3.5 ppm FC per day to your pool. See if your FC rises or falls over several days.

Start this when your FC drops below 10 ppm. Might be tomorrow.

When you run the 12 hours is up to you. You only need to run your pump at an rpm enough so the SWCG is generating.

Be sure to open your cover every other day or so for several hours in the afternoon to burn off CC. Hopefully you can swim too!
