I use a 1C9 T&O cartridge. The bowl is clear, easy to see if it's dirty. Yes, it filters all the water. As long as the chlorine stays at a reasonable level, it should last about 9 months. I use one cartridge all season, since we're not full-time (yet!). Even at full time, the cartridge should last a min of 6 mo. The cartridges are about $14 ea. The filter unit is about $35. I mounted mine from an overhead bracket, connected with stainless braid washer hoses. Easy install. > Thanks in advance for the info. > Best regards,
