Hi, I've decided that I may have to drain the entire pool after testing all the chemicals. No Partial drain. I have an in ground plaster pool, about 30,000 gallons. I'm trying to have this done before the water rates increases next month. My pool has some sort of scaling or rough spots on random spots of the pool floor it has some sort of discoloration...and when yellow algae grows, it needs to be brushed more than once in those areas.. Is there something I can do to make it smooth again and remove this? I'm wondering it there it is something that I can do myself..trying to save money. I also want to make sure I don't miss anything that I should be doing while the water is out..or to look out for? I don't get why they say don't drain it in extreme heats, is 70-75 degrees okay? Also my pool is built near a edge of a hill (where it starts to slope downwards) and the dirt looks really dry. I is my pool going to pop out? Thanks!

Thanks for the info! I don't have an SWG. My pool is a 35,000 gallon in ground plaster pool. So a pool can pop out? should I go straight to a half drain and save money before the JUNE water rate increase? or should I stick with the 2ft drain refill you mentioned? Also, Ive been trying to battle a high TA by acid and aerating. The weird thing is that before I tested it at the store, my tester said had TA of 160 (a tester from home depot). I came back and tested it again and it still says 160. Maybe my tester? Either way I bought the expensive one mentioned on this board and still waiting for that. I'm kinda knew here and I appreciate the help.

I went to go get my pool water checked and got these results? I'm not quite sure what total dissolved solids mean? FC-3 TC-3 TA-3 PH-7.2 TA-110 CYA-100 TDS-Off the meter max was at 3000 I think Should I drain the pool? I know that I might have to because the CYA but if so..how much do I drain? Can I get Away with half of the pool being drained? Thanks for your help!
