It seems like much of the energy required to push the water to the roof is regained when it goes back down. Think of moving a rope over a pulley with a weight on each end. What required energy is most likely the friction of pushing water through all the small tubes, which I think normal pool...

I am eyeing the Enersol Solar system, would be nice to have a couple extra months to play in the pool. Aside from wondering if this system is any good, I was thinking in Arizona I might be able to get away with using a smaller area, since it gets pretty hot here anyway. This true? Any other...

Leslie's has them both, with the regular non-plus one for $510, roughly $250 less. So what does the extra $250 get me? Is SwimPure (plus or not) a decent system?

Found this interesting link. Would be cool to have something like this (assuming it is accurate) in the School for us nerds: http://www.chemicalforums.com/index.php?topic=34286.0

Does TFP have any recommended vendors, online or not? Are there ever group buys, deals etc?

The pool store today looked at me weird for wanting to use liquid chlorine, saying it would be gone within a day or 2, and it is only really for shocking. They seem to think I couldn't deal with tending to the pool every day. How much liquid bleach should I be using? I think they have 10%...

So how is this not a huge issue for everyone? I assume most people use tablets and dichlor shock, so how do people prevent CYA buildup like this? I don't want to have to drain my pool every year Maybe I should get a SWC?

Thanks for all the tips guys. All this time I have been using the tablets with the floating dispenser thing, and dichlor shock, on advice from the pool shops. It seems like everyone would run into this problem eventually using that. Guess I'll be buying bleach from now on.

I drained about 1/4 tonight, maybe more. We'll see how it goes... Should take the rest of the night to fill back up.

I live in Gilbert Arizona, near phoenix, so it gets plenty of sun.

Here are numbers from the shop: Free chl: 5ppm Total avail chl: 5 Cya 100 Total alkalinity 80 Ph 7.6 Dissolved solids 1500 Phosphates 200. Maybe it is just dusy here? This is my first summer owning a pool

First off: Pool is pebble, in ground, chlorine, about 12000 gallons (I think). All chemical tests are within limits according to my local pool shop. 300lbs sand filter. Lately I have been getting very fine dust on the bottom, where the creeper doesn't reach. I can easily brush or vacuum it...
