I'm brand new here and to pools care/maintenance in general. I've been through "pool school" on this site and am ready to go. My 21'x52" AG round just went up this weekend. It has been filled (city water) to proper level and I have had the filter running on and off over the last 24 hours. I plan on getting my water tested and all chemicals needed tomorrow. In the meantime, does anyone have any advice, tips, etc for startup of a BRAND NEW pool with new water? Also mulch or stone around base of pool? Thinking mulch will fade and get muddy.
