How do I determine the right amount of chemicals to start up my new pool?

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.

Depends, what size pool do you have?

An idea would be, "Which gas could you fill a volleyball up with that would make it go better?" They you can have regular air, carbon dioxide, and helium. Then you make a hypothesis based on what you know, try one of them, and see if you were wrong.

You can have different sizes of the pool, for example: \n20 ft. wide pool 1800:20=90ft. long \nor 25ft. wide pool 1800:25=72 ft. long\nor 30 ft. wide pool 1800: 30=60 ft. long\nI would clarify with the owner what pool width he or she prefers.\nFor the side decks we add 2x5 ft.=10ft to the chosen width of the pool \nFor the end decks we add 2x10ft.=20 ft.to the length of the pool \n\nthus the pool site should be over\n\n(20 +10) x (90+10)=30'x100'\nor\n(25+10) x (72 + 10)=35' x 82'\nor\n(30 + 10)x (60+10)= 40'x 70'\n\nPlease remember to add the pool clearances from the property line as per local municipal codes. Also, the machines used for digging have to have access from this property, not from the neighbours yards.  The smaller they are the more difficult and expensive the job is. \nIf we add about 10 ft. for access (and clearance) on each side we end up with a poll site: \n(20+20)x(90+20)=40'x110'\n(25+20)x(72+20)=45'x92'\n(30+20) x(60+20)=50'x80'\n \nAn addition of the area needed for the house will give you the minimum lot size required.\nGood luck!

Lemonade bottle (fins will help) and a water/air ratio of 1/3 : 2/3 makes a good starting point. The rest is good old trial and error!

Some oxide of chlorine. No idea about which one would be stable at those conditions, though.

I would just recommend looking at a can and seeing what is the propellant.  We could guess all day, but as long as we don't work in a silly string factory we couldn't be absolute.  Alot of that kinf od informations i proprietary.  But how about this:\nPropellant\nSomething that dries fast (isopropyl)\nA plasticizer to keep the goo gooey\nsome other stuff

Here is a good guide\n\nhttp://dbhs.wvusd.k12.ca.us/webdocs/Stoichiometry/Limiting-Reagent.html

That's completley dependant on what the contaminant is, how large of a site it is, and the site location.  you should consult both a civil and an environmental engineer for the specifics

keep your pool clean.i don't know if chlorine is good for your pool.\n\nthere is a website below that i hope helps.

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!

This is a limiting reagent problem. The first job is to figure out how many moles of each reagent you have and then figure out which one will run out first because that will determine how much product you can make. It is easiest to write out the balanced equation first to see what you are dealing with:\n\n2Na + Cl2 --> 2NaCl\n\nYou have 23g x 1mol/23g the molar mass of sodium = 1 mol of sodium\n\nYou plug the standard pressure, 1 atm, the volume, 0.56 L, the R constant, 0.082, and the standard temperature, 273 K, into the ideal gas law formula PV = nRT and solve for n.\n\nYou get 0.0250 moles chlorine gas.\n\nThen figure out how many moles of chlorine are needed for the amount of sodium you have.\n\nfor 1 mol of Na you would need 1 x 1/2 = 0.5 moles of chlorine. But you only have 0.025 moles so this must be the limited reagent.\n\nNow you must figure out how many moles of NaCl form from 0.025 moles of Cl2.\n\n0.025 x 2/1 = 0.05 moles of NaCl.\n\nNow multiply this by the molecular weight for NaCl, 23 g/mol for Na and 35.5 g/mol for Cl = 58.5 g/mol total\n\n0.05 mol x 58.8 g/mol = 2.93 or about 3 grams of NaCl formed

I fill it with a whole bunch of the little tablets about twice a week. It works great as a supplement. I put a big slo tab in the skimmer, and change it out when it breaks down. It depends on how much sun your pool gets and how many swimmers you have. More sun and swimmers=use both the skimmer and the "ufo" Hope that helps

We have had both above ground and in ground pools.  The above ground was easier to care for but I would not recommend baking soda.  We found the most economical way, believe it or not, was a good pool company.  It can be a real headache and expensive to balance those chemicals yourself.  Check with a reliable company and you might be as surprised as we were.  You might also want to check out the Arm & Hammer website that says it's OK if PH level low.

I've swum after adding muriatic acid to my pool.  Your eyes might sting a little.  I'd wait till 6-12 hours for worry free results

How about the red fountain experiment with acids and litmus solutions? mail me at pr4kane@yahoo.com for furhter details on it. u can try electroplating,bleaching by chlorine/so2,the brown ring test with sulphuric acid etc.
