The sand will go inside the filter tank. It usually goes in through the top of the tank; often there is a valve or dome on the top of the tank that would be removed for the sand to be added through. Others will have the top of the tank taken off.
Sand pool filters are available in a variety of sizes, for both above-ground and inground pools. The amount to put in can range from 50 lbs to about 300 lbs for residential use depending on the size of the filter. The correct amount to use can usually be found right on the label on the tank (assuming it’s still readable). If this is unreadable, if you at least know the make and model of the tank, I should be able tell you how much sand to put in. (Normally the old sand would be removed first; unfortunately, this can be more difficult.)
It is generally not recommended to use more sand than the manufacturer suggests. The filter is designed for a specific amount of sand in the tank (in order to get the proper flow rate, filtration, etc.) Too much sand would likely slow down the rate of water passing through the sand and increase the operating pressure on the filter, as well as cause sand to leave the sand pool filter when backwashing.
However, I would find it somewhat unlikely that they could actually get 500 lbs. of sand in that tank. (Assuming they’re using the correct #20 sand) The proper amount (350 #) should bring the sand level to within 6″ of the top of the tank, (from the manual on that filter) so there probably wouldn’t be room for much more than that. They may be mistaken…
