Been doing TFP since October (only owned this house 8 mos)... anyway-- we SLAMd and SLAMd and got rid of our mustard algae, came back again, we SLAMd again... it's like after we SLAM it and pass the overnight test a month later it's back even tho we keep up our levels... what's the deal?
For instance, last SLAM was Nov 1-4, then we let it drift back down to normal level... now, Dec 6 we suddenly saw a faint patch of yellow on the side of the pool-- it always starts on the same wall... UGH!
ast time, I even had my husband swim around with a syringe of chlorine (from like a kids medicine syringe) and shoot it behind the light, into the drain on the bottom and around the laddar underwater! Is this happeneing becase our bottom drain is not in use? (So annoyed at how they plumbed this but the home inspector said it was allowed.)
So, we will SLAM again, but why is this happening if we pass the overnight test, have a CC of 0 and make sure to keep eveyrhting else at rec levels? I mean, it's faint and it's just one wall, but I know it'll spread quick without SLAM.
pH= 7.8 (this is always rising and having to add acid weekly)
FC= 9
CC= 0
ALK= 75
Calcium= 175
CYA= 65
THANK YOU!
