Holding tank monitor help?!?
So my plan to build holding tanks is coming along. I am bit hung up on holding tank monitors. I am unsure of what brands and styles are best. Do the sensors attach to the inside or outside of the tanks? Can anyone help?
What are the thoughts on fiberglass fresh water tanks? Would this be safe? Flavour the water?
I have seen a number of "professional" conversions that use a combined black/grey water tank. Any thoughts?
