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

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

[gregzz4]

I've sent an e-mail to a local pool/spa joint (the guys next to J&L) so we'll see what's available locally after the weekend

Cool. Keep me posted Greg!

I read up on carbon dosing (biopellets) and alkalinity. The consensus seems to be that if you carbon does, then the Alk has to be close to natural seawater (i.e. 7-8 dKH).

It took about 4-5 days of no Kalk and no Alk solution added to bring the Alk down to the desired range. It read 7.6 this morning, which is in line with yesterday's reading. I've also been feeding the fish a fair bit and adding aminos and BRS reef chili for the corals, just in case the corals were starving. This morning I had the best polyp extension I've had in weeks. Hopefully this means they're out of the woods.

Now what?...

No luck
The kit I looked at today only tests up to 13ppm
I'll let you know if I find something on the web ...
