Approx. 5 to 15 minutes. Or enough time for the circulation system to disperse the chlorine. Or you could add it to the opposite side of the pool. Remember not to add the acid to closely to the skimmer or main drain.
It can be added right away as long as you add it at the opposite end of where you added the acid.
1 hour
You can use muriatic acid to clean or etch aluminum. Do not let it set too long or it will eat through. Use caution since muriatic acid is very caustic.
1 week
You can get in imediately without worrying about hurting your self.

Yes as long as there is wter in the pool first.
not long term, I would be more inclined to go with polypropylene.
yes
About 2 hours should turn it all over nicely.
Cement mortar should be allowed to set overnight before disturbing, several days if you plan on washing it with dilute muriatic acid.
no it could not but it would disolve flesh it may etch a bone over a long period of time but will not disolve it i am hell wasted
The answer: YES. Muriatic acid is the best solution for cleaning scum off of fiberglass hulls. Forget expensive hull cleaner or any other "marine" product that claims to remove. Muriatic acid removes all scum/discoloration without any effect to the gel coat for about $6/gallon. Get a garden/lawn sprayer, an open area (for venalation), long pants/shirt that you don't care about, rubber gloves & goggles. The Muriatic acid will do the work, only light scrubbing may be necessary as the chemical dissolves the scum itself. Once the acid has sat for 5-10 mins, spray with water and then wash with a mild soap. In the end, you will have a brand new looking hull. Remember to wax after to protect in the future.One word of caution is that the Muriatic acid fumes are very powerful. Be sure to be in a well venalated area and wear a painters venalator mask if necessary.Enjoy your brand new looking hull!
Muriatic acid or hydrochloric acid (HCl) will not harm copper pipes. I am a licensed Heating& cooling technician and I use Muriatic acid all the time to clean out hot water tankless coils and boiler hot water coils and I have seen it used to clean out hot water copper piping in houses to remove scale and mineral deposits. I use a 1/6 Submersible pump that i purchased at Home Depot. It's not a chemical pump and I have used this pump over 4 years and i have ran Muriatic acid through it at least 60 times and the pump still works great. I even took the pump apart to see if any damage was happening to it and it looked just like new. just wear long rubber gloves and full goggles for your eyes. safety glasses will not protect your eyes. the acid can splash up under the safety glasses. If you get any on your skin just rinse it off with cold water. Muriatic acid or HCl cleans up really well with water.
