We got our 24x52 intex ultra frame pool off of a neighbor bec. They were moving . We just got it set up and ready to turn everything on . The only problem is there isnt a label on top of the sand filter so were not sure what we are turning to. When my husband turned it on there was a little sand comming out so he turned it off and turned it another way and sand started shooting out into our pool and there is quiet a bit in it. I turned it until there was no sand comming out when i turned it on .im not sure what i have it set on or if it is the right setting . Is there anyone who can tell me what i can do since there is no label on the top. The sand needs to b vaccumed out !Any advice will be appreciated ! Thanks
