    You could get a cheap luxmeter from Amazon and put it in a plastic bag. That's what I've done.

    Cheap is relative, but I don't think you'll find anything under $150

    Yeah, but at $155 vs $350+ it's still a pretty decent option

    I thought I heard you can get a replacement for an old sensor up to the new version for around $50. If that's true, you could try to find an old broken sensor out there and get it swapped.

    I have the biotech marine btm3000. At $195 it's not too bad. Just hooked up to your laptop instead of a handheld.

    If there is a local reef club see if there is one to borrow. If you are in Richmond, VA you can borrow mine.

    It is definitely a big expense for something that will sit on the shelf more than anything. After getting my lights initially set up and tune in. I think I have only pulled out one times since then. If you're anywhere near South Carolina i can try and help out.

    That is a good deal, but $150 vs $15 is still a huge difference if you're on a budget.

    A PAR meter is nicer, but I would not reef without a light meter and lots of folks can't afford them.....get a lux meter if that's all you can afford.

    Once you at least have a lux meter, as a half-step toward a PAR meter, a plain lux meter can be calibrated with a PAR meter if you really need PAR numbers for some reason. (Mostly, you don't.) But this will give you an accurate conversion factor (as accurate as the PAR meter you use) to apply to lux readings from the meter. Your reef club or a LFS might rent or loan you a PAR meter, or you might know someone who has one.

    A lux meter can even be converted into a PAR meter, if you're into that kind of DIY. :) It's not too hard:
    Cheapest PAR Meter DIY - The Planted Tank Forum (There are actually lots of DIY PAR meter plans, this is probably the simplest and easiest and cheapest one.)

    Thank you guys I really appreciate your help but I'm in Dallas Tx! I figured if I bought one it would sit awhile until I bought a new light or something but I will see if I can get someone to let me borrow there's! But thanks again!

    @saltyfilmfolks I didn't remember a little detail until I just re-read that DIY link I posted....for some reason Hoppy specified against using the red lux meter for his DIY.

    Obviously it's fine as a lux meter, so I wonder what the internal difference is??? Unfortunately he didn't go into why, just said to use the LX-1010B and "not the red one" cuz it didn't work.

    Definitely get an LX-1010B to have on hand in case you can borrow a PAR meter – calibrate that lux meter! ;)

    Since you said cheap and good in the same sentence you'd be just as well off getting a submersible lux and getting help converting to par as to buying a cheap par meter. Especially with LEDs
