Cant see colors What HANNAS to buy?
I have been using Redsea tests for a couple years now and i am to the point now where im done with trying to tell if the shade of this is red or rose or bla bla bla bla. I want a way to test that will tell me accurately what the levels are. I dont necessarily mind the work but i cant tell the different shades of reds, blues and purples. I know there are many hannas and i think the phosphate one has 2 or 3 different ones. They are pricey so i am hoping you guys can tell me what ones i need. Please dont use acronyms because i dont know all of the acronyms people use.
Also does anyone have them for sale?
