So since I can't read the color difference to well on my test kit for phosphate, I figured it was time to get a hanna checker. I see the two best ones for me are the ULR and LR but I don't know which one to get. I know that maintaining a reef tank in the ULR checker's testing range is probably best, but I don't have corals yet (but I'm not afraid to try to keep those levels for the near future). Also I hear that there are going to be swings in phosphate during my first year which would mean the LR is most likely better for that. So which one do you think I should get? Thank you for the help.
