Ok - I decided last night that I would drain-out our tub as our water hasn't been too great lately. About 2 months ago I did scheduled water change and noticed that my 'fresh' water once filled, had a greenish-hue to it. Also, I noticed that the Bromine level took about a week to bounce back to proper levels (using the floating puck system). I couldn't get any solid answers on the colour problem - we've had tons of rain here this spring/summer and wondered if that had any effect. Not sure.
Anyways, I've since learned that the pucks only help maintain the bromine level, and that I would benefit from an initial shot of bromine concentrate - which I did.
I tested the water out of the tap this morning- zero bromine (thankfully), and perfect alk and ph. After adding some concentrate - Boom! My ph was off the charts and the alk was nowhere to be seen. Also, I have not been able to get any reading on the bromine level at all - even after putting in three large caps of it.
As I stand now, after all day, I've managed to get my ph into normal zones, my alk is still missing as well as my bromine. To top it off, initially, after this fill, my water had a skim of something across the top (oil slick?) and still had a greenish-hue, but not as bad as before. I've also changed filters again (disposable). Also, I've been advised by my dealer that because of the composition of this filter, I do not need any stain or scale.
I've since dropped off a sample at my dealer, but am waiting for results as they were busy there today.
Not sure what the nature of this post is. If anyone has any input that would be great. My initial water management used to be a snap, but lately I'm struggling a bit. Not sure why.

I use bromine pucks in a floating feeder. No ozone.
