Q. I have a Hayward 160T high rate sand filter. How often should the sand be changed? Every 3 - 5 years.

Q. Can you over shock a pool when you first open it? Only in the sense that a liner or some of the equipment will not like ultra-high chlorine levels and depending on the shock used you can mess up pH and Alkalinity...generally you shock with one pound per 10K gallons.

Q. What type of sand and where can I get it? #20 silica sand...some places will call it fine sand. Do not use the coarse or medium coarse sand.

Was wondering how to change the settings on filter. Its a Hayward Pro Series High Rate Sand Filter and the instruction manual says it have about 5 different ones....i.e. waste, recirculate, but we were...

If you know how to place the valve into the backwash and filter positions you need to use these. The others are important at times but they are not as important. In fact another type of backwash valve has only two positions. This valve is one of the most popular valves for this function so it must not be too bad. I hope this helps.

I replaced the sand in the pro series high rate sand filter im getting sand back in the pool?

Above is the link to all hayward sand filter manuals, with parts diagrams.
The most common cause of sand getting through after a change-out, is a broken lateral. The laterals at the bottom of the filter are very fragile, and prone to breaking. When refilling the filter with sand, it should be 3/4 of the way filled with water first to take weight of of the lateral grid. One other possibility is the air bleeder line has come undone. Regardless of which one it is, you will have to go back in and find out.

Use the above link to the parts diagram to identify and order any parts neccessary. Laterals are cheap, so if your doing one of them, you might as well do all of them.
