Hi all,
cheers Darrel
Assuming that is really hydroxide rather than hydroxyl, it could. They would raise the pH (O-H), and are a strong oxidising agent. However, this is really back to the ozone argument, why would you want to add it to the aquarium? and if you did you could always add a small amount of "caustic soda" (NaOH) instead.Could it be creating hydroxyl ions?
The colour change is caused by the higher pH, but my suspicion would be that this is an oxygen (O2) rather than a hydroxide (O-H) effect (re; the perkier fish).DC the morning following day of installation was solid blue, first time it's been back to blue on a morning. Water definitely clearer. Fish more active (some quite frisky behaviour from my P. Ivantsoffi rainbows and BP tetras that they haven't exhibited to such an extent for a while)
