The most important chemical is chlorine; keep level to 1-3 ppm. After that the next most important is Ph control; keep it near 6.8; add Ph plus to increase ( usually a sodium bicarbonate) or Ph minus to decrease.
Sorry, that Ph should be near 7.2, not 6.8
The pool volume is 3.14 x 18 x 18 X 4/4 = 1017 cu ft - that's how much water you will need. 1017 cu ft = 7600 gallons
You need 0.6 fl oz for 1,700 gallons.
if you meant to ask "how many gallons of water do you add to 15 gallons of liquid if you add 100 gallons per quart of liquid" you need to add 6,000 gallons of water
You will need a maximum of 11,230 gallons of water.

the three things that need to be cleaned from water are chemicals,germs
There need not be any water in the pipe.Assuming that it is a 10 inch diameter pipe, then its capacity is 4.08 US gallons.
I take it that there should be percentage signs in this question. How many gallons of pure water must be added to 10 gallons of 30% saltwater to make a solution that is 25% saltwater?" If 30% of the 10 gallons is saltwater that means that 3 gallons are saltwater. As only pure water will be added, we need to find out how many gallons = 100% if 3 gallons = 25%. The relationship of 100 to 25 is 4 : 1, so there will need to be a total of (3 x 4) gallons at the end of the operation. As 3 x 4 = 12, and as we started with 10 gallons, that means that we need to add 2 gallons of pure water.
There need not be any water in the pipe! The volume of the pipe is 1044 Imperial gallons
Gallons of what? Different substances have different weights, so you need to be specific. If it's water, then you need to specify if it's salt water or fresh water, since they don't weigh the same.

I think it might be a 3:1 ratio like water to rice but cornstarch so actually 30 gallons to 10 gallons of water
