BTW @NewGrower2011, the unofficial guide explicitly states that SLF-100 and H2O2 are intended to operate in parallel.
Quoting the manufacturer, Newton Hayes:
Arriving late to the party,
I see that SLF-100 is being advertised everywhere (including the 'unofficial guide' ) as H2O2-compatible.
Kind of a strange advertisement for a microbe-based enzymatic product, isn't it?
