Supermom,

I'm thinking cartridge because of lower maint in that there would be no frequent back washing. Though I may be wrong it is my understanding that the cartridge filter is not much more expensive but does require a bit less attention.

Pool Doc,

I'm in North TX and my pool spot would see about 3-4 hours a day of direct sunlight....would that cause heating issues? My wife is pretty set on a dark bluish color.

Thx!!!!
