Issue with Randy's 2-part!

[MSU Fan]

I know that a bunch of us are using 2 part to do calcium and alk supplementation, so I thought that you should all see this thread if you haven't yet: New Randy's 2-part .

Bottomline: apparently the dowflake of recent is very high in bromine (as compared to previously when Randy developed his 2-part). It is unknown the effect on reef tanks yet, so this may be a false alarm. However, the levels are outrageously different (NSW=67ppm, new dowflake = up to 8,000ppm).

A suitable alternative is still being located, however Randy is only "consulting" on this one. Just as an FYI - the prestone driveway heat is also affected by this...

The dowflake produced under the new method was made after December '06, and people are still getting the old stuff. If the lot code on the bag of dowflake had a "U" or a "PC" in it, or a production date after 12/06, then it was produced with potentially higher bromine levels.
