Taylor kit should be here Monday. Yes it is yellow capped solution added for chlorine test. I also noticed in my pump basket sand underneath when I took it out to empty it and sand on my buddy seats -there are 2 returns on those seats. I am assuming this isn't good. My first year opening pool on my own and getting frustrated. Please help. How many 121 oz juga of bleach should I add? Also what about putting a tablet in skimmer basket?
