The best thing would be to use the pool vacuum with out the vacuum head. You will have to swim down to the bottom so wear shoes so you don't cut your feet. Just stick the hose over the glass. Also use a vacuum plate over the skimmer basket. DO NOT SUCK THE GLASS INTO THE CONNECTOR HOSE ON THE PUMP IT COULD CUT IT. Be careful when cleaning the skimmer basket wear some heavy gloves.
This is a very difficult situation, the best method would be to hire a diver to gather all the shards. Pool cleaners are not recommended because of the high probability that you will damage the liner and end up having to repair a lot of leaks.
Try to scoop as much out of the pool with your net as possible. If you have a sand filter, follow instructions on repositioning the valve to "waste". If you have a D. E. filter vac as normal. Start adding water to the pool with a garden hose to offset lost water by running the hose end slightly under the surface of the water to prevent ripples on the surface of the pool. Set up your hose and vac head and vac to waste covering the floor in a grid pattern then a cross pattern then again in a gird pattern from the opposite side of pool - the intention is to cover every possible sq. in. of the floor. Return your valve back to the filter position and vac the pool again thoroughly. Brush the pool and vac again. Before pulling your vac hose out of the water walk around the pool and check the pool floor for more glass. Checking from all angles gives you a chance to have the sun reflect off of a small sliver. Pull your hose and vac head, emptying the hose of residual water and check hose and vac head for pieces of stuck glass making sure no glass punctured the hose. Check the pump basket for glass and empty also checking the bottom of the pot under the basket. It might be a good idea to make a note for the next time the filter is dismantled for annual cleaning to remind yourself or the pool tech that there was glass in the pool and to be careful for glass within the filter tank itself. Glass is so very hard to see in a pool environment and you need to look at the pool floor from all angles from the deck.
Drain the pool..Its the only away one can ensure to get all of the glass out..
Call a local pool store and ask what they recommend in lieu of draining the pool.
Drain pool Sweep out all broken glass, refill pool. Some cities or counties require that you call water dept before you fill a pool.
Yes, replace the liner. Nothing can put the color back into plastic or vinyl or glass or steel.
To clean algae from a vinyl pool liner after it has become crystallized, use a solution of bleach and water with a scrub brush. One cup of bleach for every 5 gallons of water should be enough to clean the vinyl liner. Rinse well, then let dry before storing the pool.

Well first of all there is no such thing as a fiberglass pool. You can have fiberglass walls instead of steel but your pool is still vinyl because you need a liner. These are the usual combinations of inground pools. Sand floor, steel walls, vinyl liner Sand floor, fiberglass walls, vinyl liner Vermiculite floor, steel walls, vinyl liner Vermiculite floor, fiberglass walls, vinyl liner Concrete floor, steel walls, vinyl liner Concrete floor, fiberglass walls, vinyl liner Concrete floor, concrete walls, no liner Concrete pools have to be painted with epoxy paint or if you want tile installed then usually you plaster over the concrete. Now a days 3 and 4 are the most common inground installs. 1 and 2 are usually pools that are 30 + years old although you can still have them done that way. In South Alabama the cost of a 20 *40 vinyl pool will cost around 18 to 22 thousand
We used Garrett Vinyl Pools they have been around for years.
