Newbie - with cloudy pool

[Dad2handz]

Hi all! We have had our pool for about 5 years. It is a True L shape vinyl liner pool that is 16x36x41 in size with a deep end of 9 feet. We went with the True L due to the difference in ages of our children and the fact that we had a larger area for the younger one to play in and also have room for the older one to enjoy the deep end. We have a salt water converter on our pool and in the last 5 years we have replaced the salt cell (last year), hayward pump twice (also last year for the 2nd time) and the mother board in the salt converter twice. Seems it is always something breaking with our pool. I believe this year we need to change out the sand in the filter which doesn't sound very fun but I am sure will be needed.

Opening the pool this year, it is very cloudy. I have been able to shock the pool and then use EZ Chlor Drop Out and the debris all settles to the bottom quickly and vacuum to waste. For some reason not having luck with that this year.

Hope to continue reading to get help with our pool issues. Thanks!
