Question on the use of potassium chloride as a substitute for potassium sulphate. Chuck Gadd's calculator lists potassium chloride, % breakdown, etc. Wondered if anyone has used it in their aquarium? My only concern with potassium sulphate is perhaps the negative effects of sulphates in the aquarium. I was wondering if any info was available on its usuage, pros and cons, etc. Also, where to purchase, and if there is a trade name for this chemical? Does it dissole readily in the aquarium? Didn't see it on Greg's website.

I've seen some discussion of Potassium Chloride on the APC forums. I haven't seen any enthusiastic endorsements, but more of a "this is available to me - can I use it" ... and in general, the answers have been - yes you can ...

Personally ... the "thought" of adding chlorides to my aquarium creeps me out a lot more than sulphates ... but I trust that if there was a legitimate reason why you "shouldn't" ... that I would have seen or heard about it ...

So if it is available to you in a cost effective manner ... give it a try ...
