opening pool - water test results

Mike, that is what I do. I use my OTO kit daily or at the very least, every other day. Then, I use my K-2006 occasionally. It makes the reagents last a lot longer and for every day use, the OTO/Phenol Red kit gives you all the info you need. If you are fighting something in the water or trying to clear up a pool, you need the FAS-DPD component for testing higher chlorine levels than an OTO can handle but otherwise, the cheaper kit is sufficient for most daily testing. (Plus, replacing the OTO refills are cheap.)

im opening my pool just now for the summer and coming back to this thread to to see the level of chlorine i need to be at.

Just want to say thanks again for all your help and great advice. i stuck with bleach the entire summer. i thought it would be a pain to drop in the bleach each night but once i got into the routine it was easy and i didn't have one algae bloom and my water was crystal clear all summer. thanks !!!

thanks for the follow-up feedback; we don't always receive that.
