Hey NR community, need your help!
I am considering using a stand alone doser to dose Red Sea foundation ( alkalinity and maybe calcium periodically) and would like to first figure out a good way to fail safe it so that I minimize my risk for overdosing/catastrophe.
I DO NOT have an apex nor do I really want one for my nano, so I don’t think it’s possible to use the pH method to turn the doser off if the pH rises above the set parameter. I’ve heard of some people using outlet relays... but I’m not sure that will work.
Does anyone have ideas on how I might be able to fail safe a stand alone doser without an apex? Thanks so much!
