Oh right... I totally forgot that I could take some water to the LFS and get a second opinion.  Now if I can just manage to go to the LFS and NOT buy anything that won't survive the merging of tanks... Embarrassed

I'd shake up the CA additive and add it to a little RO water, see if any solid white chunks drop to the bottom that won't dissolve, if a lot do then it's not going to be 100% potent but is still usable.

The Alk is likely fine.

The CA and Alk are liquids, but I think I have some powder too.]]> Thu, 31 May 2012 15:06:26 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=56839&PID=469617&title=old-stuff-still-good#469617 <![CDATA[old stuff still good? : From what I can tell after...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=56839&PID=469615&title=old-stuff-still-good#469615 Author: aquablue

From what I can tell after checking some test kits I had left over in storage for nearly 5 years they seemed to work just fine when compared to my new kits, I can't speak for all types of regents and test types but my CA and Alk kits were fine I know.

The iodine (potassium iodide) additive regardless of what the date on the bottle may say has a stable lifetime of around 6 to 7 years before degrading, and after that it's still a slow decay.

Are the CA and Alk additives powder or liquid?

I have a bunch of test kits and add-ins that are at least 4 years old... They have been stored in drawers so they have been kept relatively cool and dry.  Are they still good or should I invest in new stuff?  Add-ins include CA, Alk, Iodine, etc... do these "go bad" or can I just shake them up and use them like normal?]]> Thu, 31 May 2012 13:13:24 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=56839&PID=469606&title=old-stuff-still-good#469606
