If you use a cooper based algeacide than yes it will. There are a veriety of diferent types of algeacides and the blue (cooper) ones tend to be cheaper, but too much will turn blond hair green. Pool Masters
It can maintain the cooling temperature of water and 80% of copper is available.
Using copper washers as opposed to using aluminum aren't to much more beneficial except for the fact that copper is more reusable. On the down side copper is more expensive.
"How much" as a question is quite vague. Some hot water heaters are comprised of copper only. So this now depends on the size of the hot water heater. Some hot water heaters have no copper whatsoever.
Over use of copper based algaecides tends to cause the pools grout and other surfases to get a blue green tinge. You also should refer to salt water chlorinator specs before using them in salt water pools.
Copper stays where you put it much better than saline water does.
Copper does not sink in water.. An object with higher density than water sinks while an object with lower density than water floats..
Not much. The Copper (II) sulfate will just dissolve in the water (at about 316g/L of water). Copper (II) sulfate is pretty friendly around water and not all that dangerous. It's used commercially.
up to 2.300 PSI
Copper pipes are perfectly safe. If you were to consume too much copper you could then suffer from copper toxicity, however metallic copper is not very soluble in water, and you will not get any excessive amount being dissolved by using copper pipes. Also note that in very small amounts, copper is actually beneficial, since it is a necessary trace element. So copper pipes are good. Or what I was told is that the Romans drank out of copper pipes and they all went mad but that's what i heard.
It would take 100,000 liters of water to dilute 1 liter of copper chlorine solution.
The solubility of CuCl2 in water is 75,7 g/100 mL at 25 0C.
Did you not read the label instructions? Why do you need that much in a very small pool? I would recommend to drain partially and refill however I would hesitate to dump that much toxic chemical into the streets and into the water supply or ocean. Try draining to the sewer but be careful for overflow into the shower or toilet.
