welcome to te hobby any questions just shoot |
I use prime in my tap water and my parameters are great, not perfect but darn close, I do use a tap filter to for heavy particles, but theres obviously as said still trace nutrients and elements in the water, ro di is nice, but its realy your call in the end, you can also use bottled water the distilled kind with no added nutrients, for usually 30-50 cents per gallon
