First post but I've learned a lot from this board.
Today I noticed a small spot of algae and need to start the shock process.
Since I know I'll be asked ....
CH 166 *was next on the list to deal with
I have a very high exposure to UV and normally use a LOT of bleach. I am converting to SWG (I have it but haven't installed it yet).
I know my CH is low so would this be a good time to break from using Liquid Bleach to shock and use Cal-Hypo? and/or Dichor? My CYA is too low for a) my UV exposure and b) installing the SWG.
Water still looks crystal clear but I had a several small spots of algae on the wall. The water has never fallen below minimum FC.
