Its time to replace the filter on my 20x40 inground pool. Right now we have a Nautaulis DE filter. I have talked with several pool companies to get estimates and most are recommending to stick with DE (Hayward 48). However some are saying why don't you switch to Sand - less maintenance, etc. Other pool companies are telling me we probably would not be happy with the clarity of the pool - something about microns (don't even know if I would know what a micron looks like). While a Sand filter is cheaper, its not about the money - its about getting the best filter possible - less maintenance is a bonus, but if it means a cloudier pool, then I'll do some work. Can anyone shed some light on this for me? Thanks!
