Re: [APD] Amquel and water top off
I'm no chemist but I know that a key reason for using
chloramines in the water system instead of just chlorine is
that chlorine breaks down easily and quickly into
nondisinfecting form and chloramine doesn't -- it has much
better staying power.
The old rule about not conditioners if less than 10% water
change comes from the days when only chlorine was the key
worry and chlorine leaves quickly.
That's no answer, but if it were me, I'd just add a little
Prime along the way. So long as you keep changing water out
and not jsut add water in to make up for evaporation, the
levels are limited in how high they will build.
