Anyway, in terms of pool hardware, how long do you see yourself using this pool? Assuming you do go above ground, if you see yourself using this pool more than 8 years, I'd recommend you investigate aluminum wall pools. Steel, however much you treat with TLC, will eventually rust rust rust (especially with chemicalized water splashing on it all the time). For liners, be sure that when they quote you a millage (thickness) that it includes the floor AND wall. If they give you one number (e.g. 20 mil) ask if that is both wall and floor. The wall is what takes the most pressure, but often times cheaper liners will quote a millage that represents the floor and the wall is actually thinner.
A 27' RD has about 17,000 gallons of water that you have to sanitize and filter. I'm personally an advocate of bromine for sanitation, but usually is overkill for an aboveground pool. Chlorine is common, but alot of people make the mistake of thinking they can put chlorox into a pool and be done with it. There is also a chlorine / bromine free sanitizing system which is great if someone is allergic to chlorine or if you simply want to avoid a halogen based system. A truly concerned pool owner will want to properly maintain a sanitizer level as well as make sure your pH, Alkalinity (pH buffer), Calcium Hardness (mineral demand) are all in proper balance. When these are off (low means your water is corrosive | High means you water would be prone to scaling) bad things happen SLOWLY. And this slowness is what makes lazy pool owners; they don't see the problem until it has had weeks or months to compound and then manifests itself with common problems being cloudy water, clogged filters, algae, metal stains, corroded heater tubes, tears / holes in liners. Yes, all these problems can be linked to improperly balanced water.
For filtration I'd recommend either a sand or D.E. (diatomaceous earth). A sand filter will offer the longest filter cycles and superior ease of use, while the D.E. filter will filter smaller microns of particles than sand. E.g. a sand filter will filter particles down to 30 microns, whereas a D.E. filter does as small as 7 microns. Now before you go leaping to the conclusion that a sand filter sucks, think about how small a micron is to begin with!!!! 30 microns is not that large at all.
If you have any other questions, feel free to PM me.
