I've been using the BBB method for a couple of years now and I've NEVER had to SLAM the pool before! We had some really rainy nasty weather about 2 weeks ago and it did a number on my pool chemistry. No visible signs of algae....just evident on the FAS-DPD tests and late last week we could smell the chloramines.
I've been bringing the chlorine up to about 15 (trying to go a little over the recommended 13 for SLAM'ing just in case it were to drop on me while I wasn't at home) at least twice daily and while the CC WAS 2 late last week....I'm still testing 1ppm of chloramine and NOT passing an OCLT either. I back washed the zeobrite filled sand filter when I began the process and added enough DE to bring the pressure up 1psi.....but I'm not seeing the chloramines dropping at all now!
I'm brushing the pool and spa probably twice a day and running the pool cleaner twice a day and running the pump on low speed 24/7 with high speed running about 4 hours each day as well.....
Going through liquid chlorine like it's WATER!
Any ideas???? I'm bummed b/c my pool has never done this before!
