Buy a TDS meter for $29 or less and test water before putting in $$$
batteries - this one I have and works great -- I don't know where I
got it from but this place is as cheap as any

BTW - lots of aquarium stuff is useful and cheaper than "marine" stuff

My distilled water in So Cal is .99 per gal and measures 1 ppm TDS

Got it from the 99cent store
