Well if you had a Neptune apex I have a par meter module. I wouldnt go buy a par meter just for your lights. I would rather buy a controller instead and keep looking for someone with that par meter. Also like a previous quote your corals will tell you if they like the lights.
Keep your head up brother! Its not an easy hobby, but with some slow well thought out changes you got this! If you ever have any specific questions dont hesitate to ask me as well.
I was in the same hole as you. I stopped looking and caring for a month and everything went into place. Im also pretty close to you so if you need assistance just holler.
