I will close the chlorination, how about the CH, do you recommend something? The PH and TA I am already familiarized how to balance.
Do I use Yellow Out?

It would be wise to add some calcium. Use Poolmath to see how much calcium chloride to add to get to 250 ppm CH.
Don't just close the chlorinator off, you need to remove those pucks entirely. Let'em dry and you can use them another time when your CYA is low.
Add some calcium as you don't want the water to leach calcium out of your plaster. You want the water properly saturated with calcium to prevent that. I'd aim for about 300 or so.
Adding Muriatic Acid to lower your pH will also have the side benefit of lowering that TA also.
Use PoolMath and monitor your CSI. I like to use the web version found at the bottom of this page when I want to tweak my results to play around with options to balance the water.

Hello, crystal clear. Removed the pucks, added 5 lb of clacium hardness (last owner left) added some acid. New results. I purchased in Amazon calcium will arrive thursday. Do you think tha I have to reduce even more the PH?

I forgot to mention that the mustard spots I was not able to remove it with chloride and washer pressure. Any idea? It is still with same stains.
If you are still having algae issues, then you need to perform the SLAM Process. This is a process and needs to be followed step by step. Read through the process and let us know if you have questions. When you get to the part of clear water, we can determine if you need to follow the mustard algae portion.
What makes you think it is mustard algae and not just regular algae?

It looks like some kind of dirty, brown or mustard. Did not get out with direct chloride resting one hour and then washer pressure. I dont know. It is weird. Photos attached.

After you get your pool filled back up you can try a couple of things.
If you still have a trichlor puck, you can try rubbing it on the stain. If the spot comes off then it is organic and the chlorine will continue to get rid of it. Just be careful not to leave it sitting on the surface as it can cause a bleached out spot.
If the spots aren’t changed after rubbing the puck, you can test if it is a metal stain. To do this, get some Vitamin C tablets. Crush them up into a powder and put them in a stocking or sock. Rub this on the spot and see if it comes off. If it does, it is a metal stain.
We can advise further once you know what you are dealing with.
