Waste,I'll do my best to answer,First I had a swimpro 100 lb sand filter I believe 25 GPM.and a jacuzzi 2 Sp 1 HP pump,I didn't think the filter was big enough so I changed it.Now I have a jacuzzi 190L 200 Lb sand filter, and the same pump.I don't have a manual so here is whats on the side.it reads
Filter area 1.87 Ft
Height 29.5 in
Tank Dia 19 in
Filter 47 GPM
Backwash 28 gpm
Silica sand 200 lbs
Eff size 48 MM
Maintain 12 " clearance on side and 18" clearance on the top for maintenance
and service.
Not sure what all this means but was told I needed a bigger filter.Also I purchase 200 lbs of filtered sand,but it only held 150lbs.Now I'm wondering if I put the sand in right,not sure cause like I said I don't have manual.Here is a pic of the filter.Thanks for all your help and support.
