I tested water this a.m. Using daily test and results were somewhere between 4-5 (deep yellow) which is good but also tested using FAS/DPD and results were about 2.5. The R-0870 is new but the R-0871 was purchased last year so was the R-0600. All stored inside so they don't get too hot.
Is there something that I am doing wrong or do I just need to adjust IC to produce more chlorine based on drop test
FC. 4. Or 2.5?
CYA 60 (need to bring up a bit)
Water temp around 78
I don't want the FC too high but definitely not to low so not sure what I should adjust output based on.
