Hi Randy, Sorry, no I haven't. My background is in construction (pipefitter/welder) so never had the training to do the scientific examination of the effects peroxide had on my systems. I was a hands on user/observer of most additives to my SW systems. I was a firm believer in additions of trace elements, specifically Part 1 and 2, Mag, from Ocean's Blend plus many of the Zeovit additives including iron.Have you ever tracked what effect the peroxide has on the speciation and bioavailability of trace metals such as iron?
I've been wondering if the effects some people see on dinos from direct H2O2 additions might be from alteration of bioavailability of certain trace elements.
