I don't have an RO
unit, but I do live practically next door to a natural spring water place, so I thought I would be doing better than tap water if I filled my new 75g tank with Natural Spring Water.
Now I'm reading that Spring Water can be worse than tap water.
I've done nothing else so far except add about 70g of spring water and mixed the salt in the tank. Should I remove it? What should I test for to see if it's as bad as some people have told me it could be for my tank?
I've tested for PO4
and there appears be SOME phosphates but the low end of the scale is so hard to tell...it might be zero, or it might be something ever so slightly more than zero or my eyes are just playing tricks on me because now I'm paranoid about this.
I've tested for NO3
and it's definitely zero.
What to do?????
