Long time forum lurker here who enjoys crystal clear water in my pool thanks to everyone's help. I searched the forum for this question and am quite confident it's never been asked before.
My daughter is a high school senior who actively participates in the school drama program. Unfortunately, I'm one of the dads who can't say 'no' when asked to help with set design, construction, etc. This year's season was recently announced, and the fall play is one called 'Metamorphoses' by Mary Zimmerman. (see wikipedia for plot points). Water is an important symbol throughout the play's vignettes, and productions usually construct a pool of some sort as a set element. Yes... you read that right. They build pools when they stage this play.
So after getting over the shock the school director's desire to build a pool INSIDE the school auditorium my head started to reel with the details. I did a little online research and found a relatively detailed account of how one troupe constructed their pool.
Our director wants to build a variable depth pool on the floor area in front of the stage, apparently similar to the pool linked above. For the sake of brainstorming, I assumed a 20' x 30' rectangular pool at an average depth of 18". That yields 900 cubic feet which converts (I believe) to over 6700 gallons!
I can handle building a wood-frame structure capable of containing the mass of the water. My bigger concerns are these:
- While I know a lot about keeping my backyard pool safe and sanitary, I don't know what I don't know about doing the same for an indoor, temporary pool. beyond not needing CYA indoors, do I shoot for similar levels on pH, FC, TA, etc? I'm assuming gallons of plain ol' bleach will get us through the week of tech rehearsals and performances.
- I would appreciate suggestions on heating and filtering the pool. The link above mentions plumbing and heating the pool they built for their production, but doesn't provide much detail on equipment. All I know about heating pools comes from the gas-fired behemoth sitting in my back yard. Are there electric options which may be used indoors where venting may be impractical or impossible?
- Pond liner seemed to me to be a great option for containing the water. It's expensive, tho... Are there more economical options out there? Any suggestions for a material that's particularly easy to work with?
Oh, and as if that wasn't enough, I need to ensure NO damage occurs to the school's auditorium, which was completely renovated at great expense four years ago...
I'm still not sure I've gotten over the shock of what's being asked here... So please... What ideas do you folks have to help me pull this off?
