I've got a few issues so far this summer. I'm fairly new as in just started last year in attempts to take care of this pool. It's been a challenge as large trees are way too close to the pool but that's another story.
First, my cartridge filter was left outside during our winter and has to be replaced as a piece broke off and it's not filtering properly. It's actually about 6yrs old too. My pool is only 18 ft round approximately 8,000 gallons water
I want to upgrade to a Hayward sand filter. I've been calling around to several pool stores and online.. I get different answers with each call which only adds to my confusion. One store says that I have to get a 21" Hayward sand filter because I have a Hayward 1.5 hp pump and if I go with a smaller filter the large hp pump will blow the laterals right off. First, I hate to admit that I'm not sure what the lateral is! I admitted this and the saleswoman said a lateral was like fingers that move or filter the sand. The next pool store says that I can purchase a 16" Hayward sand filter without any problem but can't go any smaller due to the pump size.
Another question I have after my phone calls to pool stores: which sand is best? Zeo sand or the other? The salesperson said that you can use 50 lbs less sand if you go with Zeo sand. Is this true?
Fortunately, I remember this website from last year and I feel confident that I will receive the most appropriate answer here.
If you could recommend any specific attachments that I might require in going from a cartridge to a sand filter I would appreciate it. I also require a new test kit too.
