I have to take apart my filter and clean it, so I went and bought the stuff to do so last night, but I also need to adjust my pH, CYA, and my CH is low. My question is, since the filter is already on the pool and I've started to get it going for the year, do I work on adjusting the water first, or cleaning the pump? or does the order even matter? And also, I have a ? about the CH. I've tested and double tested, to make sure my reading is correct, and it is at 130-140. According to this site, and the test kit instructions, it says b/w 200-300 is ideal. Is that accurate for a vinyl above ground pool? So, here are my #'s, using the Trouble Free Test Kit TF-100: (I know chlorine needs work too .
FC .5 (last night)
Thank You in advance! BTW, I have a 15x30x4ft oval above ground pool with a Hayward EC40 series DE filter (which, I'm using for the first time and didn't realize I needed to wash the fingers first so installed it before doing so).
