Yes, Greg, I meant "offline". I still use Dow Flake CaCl2. What kind of issue do you suspect?

I didn't see you mention what type of salt you are using...have you recently opened a new bucket? There can be other extenuating factors...not saying just salt but its something to consider.

Good point mseepman: I have always used IO salt. I don't remember starting a new bucket around the time of the problems. I also haven't made any huge water changes (I have been changing approx 5 gal per week). I test religiously and the parameters were always good.

I also use DOWflake for the calcium part, and Arm and Hammer baking soda for Alk. The Kalk I was using (offline now) was BRS Kalkwasser.

There's a chance it's causing my GHA issues
My problems started less than a couple months after I started using the Dow and I haven't been able to get it in check since (6 freakin' months )

Have the GHA abated since you stopped using Dowflake? Have you heard of it causing problems?

Haven't heard of any issues, but the elevated Bromide levels amongst whatever else is in this non-lab grade stuff made my mind up to switch
I've only started using it this week and expect to not see any results for a couple months
I'm thinking it'll take many WCs to remove what's in the tank now

I hope to have my new NSW tank online over the next couple weeks
This will allow me to perform 25% WCs

[straightrazorguy]

Greg, did you test for bromide? What were the levels in your tank after a few months of Dowflake?

[gregzz4]

Is there even a hobbyist kit for it ?

[gregzz4]

Hmm, maybe it's Bromine we're worried about, and apparently there are kits available online ... I'll think on it
