I installed my hayward filter today 300lb sand filter 6 50lb bags
after installing all six bags i checked the sand level according to the instructions 300lb of sand or the sand should be 6 inches from the top of the filter. so i measured from the sand to the top and was no where near 6 inches i was probably 12 inches from the top. I figured instuctions stated 6 inches from the top so i bought another 50lb bag of sand and now I am around 8 inches from the top so I left it at that. Sand is probably 6 inches from center stand pipe.
I am wondering why I needed extra 50lb sand I know you will get some sand loss from the bags that seems like quite a bit.
I have not finished attaching all my plumbing yet I plan to do that tomorrow. Do my sand levels seem to be ok ? any advice to me I am just hoping I do not have too much sand?
