Tried the 10 minute drill for myself Wed. night. Ran out of bleach after 16 gallons. I did it again last night, started around 8 pm and 22 gallons later finally got to where it would hold at 10 for ten or fifteen minutes around midnight. I put in enough soda ash to raise the pH a little, waited a while then put in shock level FC for my CYA level. I raised FC to 14 one more time before I went to sleep. Water looks great other than some dead algae that my filter will just not keep out. After testing this morning these are my results:
CC <.5 (but prob not quite 0)
pH <6.8 (base demand test was 12 drops to get to 7.4)
Questions: Should I continue raising the FC to shock level today or just raise the pH and wait to do the OCLT test?
