Cheap AP test kit. If you can assume you have no NO3(or some) in your water
and you add KNO3 at 1/8 th a teaspoon you will have least 3ppm of NO3 at a
minimum...........you can make your own dosing estimates and volume of your
tank etc and see about that tap water level or use reconstituted RO and
forget the kits and just do it by estimation and big weekly water changes to
correct for errors. This method works better than using cheap kits.

Yes. Hach also makes one.

I have a tank that's a 20 gallon and I add that much to it. If you do the
water changes, it works. If your tank is low in CO2 etc or you don't like to
do water changes etc........I cannot say.

I'd just leave it if it's 3+. The PO4 can be figured out from the water
company along with NO3. Call and ask. They have good kits there. Sounds like
the tap is fine. I'd use it and adjust your pH to where ever the pH/Kh table
say to, about 6.4 or so off the top of my head.

It'll knock out most greens/BGA. Red's and Entromorpha(staghorns) will hang
on. It goes away eventually but is work.
