To Calcium Chloride or NOT to ???

Hi, I just had my pool water tested at the local pool store. They said my pool hardness was low. 110 ppm. So they had me buy 10 lbs of calcium chloride to add to pool. I just read the container and it says that this is used to protect tile, grout and metals in pool. I have an above ground 16 x 30 vinyl pool. With a plastic hayward ec 40 DE filter and hayward pump. I think I got hosed by the pool place. I don't think I need to add 10 lbs of this stuff at 17 bucks a container.
So, should I add or shouldn't I ???
Also, if I get some heavy rain how do you drain the pool with my setup. The filter has a drain cap on the bottom side of unit but will that also drain my DE out?? I have no other drains to do this.
Thanks a lot.
Gary

I would return the Cal-chlor. and to reduce the water level just vacume to waste it will bypass the filter.

No doubt. Although I would rather think they do it because they don't know any better but you do not need that product in a vinyl pool.

I can't help with how to drain.

Ok, so return the calcium. Got it. Thanks.
The vaccum to waste to rid the pool of excess rainwater? I don't have any choices on my filter. When I vaccum the pool. I vaccum directly to the filter. There is no waste choice or any other for that matter. I have the hayward bump. EC 40.

Thanks a lot.

You can also take your cleaner hose throw it in and syphon it out. I put a good deal of it in and cap the other end with my hand and pull quickly so the water has made it over the hump.
Of course you have to make sure the water in the hose is there before you give that pull. Maybe place it in front of the return jet for a couple seconds.
