Hello All. We just had our AG pool installed 3 weeks ago. Water is perfectly clear but I seem to be getting sand from the Hayward filter on the bottom of the pool. I am also running a SWG system. I am a little worried to use the vaccum on the sand because I do not want to damage the pump. I see some people say vaccum on waste but I don't see that option and the sand will still go through the pump correct. Mabey filter sand is so fine it won"t damage the pump? Any ideas on why the sand is getting out of the housing? Any ideas would be great. I am new to the pool thing but having been running a hot tub for 10 years. Thanks.
