Take a water sample to your pool store. They will test the water and tell you exactly what you need chemically to put in your pool.

what for? for a DNA gel to separate 1000 bp to 10000 bp I'd try a 0.7 % gel (i.e. 1.4g in 200 ml). and run it for 30-45 min (watch the bromophenol blue) this is about 500bp

You will not be able to buy that solution.  It is a volitile solution.  You can however go to the pool store and buy a safe version.  Its the red one in the pool "water tester" kit.  Have fun!

No need to break it down to "molecular" other wise, try this: Sodium thiosulphate. Dont just use it coz they all vary in their Ph U know the basisity or acidity they concentrate.

To maintain the pH of the pool between 7.2 and 7.8, sodium carbonate (soda ash) is used to raise pH and sodium bisulfate or hydrochloric acid (muriatic acid) can be used to lower it.

if you are having trouble with hard water scale build up on the walls of your spa, a water softner will help you.  If your bromine level in your spa is high you should use a dechlorinator.

hmmm, I would use a diaphgram pump hooked up to a bag filter. A bag filter is a large filter housing with a large "sock" filter inside. It can hold a great deal of solids without changing..i believe they make them as small as 3 micron.

Zeagle regulators.\n\nConsistently rated a top performer and top pick by Scuba Diving magazine's comparison tests, great factory support with free annual service parts if you buy from an authorized dealer, and dealers such as ScubaToys will match prices from grey market dealers.\n\nOf the Zeagle regulators, I prefer the DS-Vs.  Simple design, environmentally sealed, highly regarded by tech divers (similar to Apeks DS4).

Chlorine is used to sanitize the water. Sometimes you use chlorine tablets through automatic "dispensers" or chlorinators, sometimes you can use chlorine in granular or liquid form if you need it to work faster. \n\nOutdoors pools also use something called a Stabilizer because the sun's ultraviolet rays reduce the effectiveness of the chlorine so the stabilizer counteracts the rays' effect.\n\nFinally, some pools are treated with salt...a complex process that I don't understand involves lights and basically generates a sanitizer that acts as the chlorine would...

Also use a "defloculant" to clump the fine dirt togather so the filter will trap the dirt instead of just letting it pass back into the pool.  You should never have to clean your filter more than a few times a week.  Back washing more than that will really screw up your pool chemistry. \n\nThe defloculator is available from all pool and spa stores and will work wonders.  You will also get ti cleaned up faster if you cut your top water intakes back and have most of the water being sucked though the bottom drain.  I have very similar problems with my in ground pool because it's located around lots of pine and other trees.  once I use the deflocculator, I can also use a fine pool net to get alot of it out too.  Good Luck!

Go to a local pool store. Bring a sample of your water in and have them check it out and give you the goods to keep it clean and clear

Well you could try to do the firefighter thing but it may just be easier to get a long hose and find someway to attach it to the edge of the pool and let it fill up on it's own then add the chemicals and chlorine and all of that stuff let it sit for a day or two and you have a pool full of water to play Marko-Polo
