so in general is it a bad idea to use tabs? Do most people here use plain old bleach? doesn't that provide less chlorine? Oh, and does CYA evaporate, or if not if the pool water evaporates in hot sun, will the cya concentration actually RISE?

New pool (7 days post fill). Our township requires a vacless anti-entrapment valve to be put on the filter line. I have a main drain and 2 skimmers. If I turn off the main drain all is OK. However, if I turn off main drain and try to isolate one of the skimmers (like if I was going to vacuum) the vacless device activates and I lose my pump prime. I found if I keep the main drain open a bit I can isolate a skimmer, but what's up with that? Won't I have a much weaker vacuum (when I start to vacuum -- I was told not to use a vac for 21 days on the new plaster) thx!

yes i did not think tabs in the skimmer was a good idea either so I put them in a floaty thing. The start up guy said soemthing about "letting the celulose (DE alternative media for filter) rest"? so he suggested 22 hours.... It is OK to use chlorine on the new plaster? Why do some people say no?

Hi all. Newbie question here but I have received conflicting advice. Newly plastered 25,0000 gallon pool (white plaster). Fill was fine, added metal sequsterant during fill. I was told to brush and keep pH~7.2 for 14 days. Start-up guy told me to ignore hardness, TA, etc. just watch the pH.....No heater or vacuuming. My start up guy told me it was ok to put a little chlorine 3 pucks in each skimmer. pump running 22 hours/day question 1: is this the only thing to do? another pool person said no chlorine for 2 weeks? Is a little chlorine OK (no shocking?) anyway pool looked GREAT for about 5 days, I was brushing 2X/day, water was crystal clear.... but a rain storm came in and my pool is cloudy.... pH was up a bit to 7.4. I added acid, Ph now 7.2, TA 70, hardness 120. CYA 0. now a little green algea is forming on the thermometer floating around..... less cloudy on day 6, but not super clear. Not getting a lot of plater dust anymore. question 2: I won't shock but is a little chlorine OK? I am at day 7..... keep Ph low still? add algecide? Thanks and much appreciated....I am willing to work at this but all the advice seems to conflict...
