    Improve your reflector for 16$

    I purchased this reflective hydroponic paper from home depot, a roll is 16$ What i did was line my canopy with the stuff and still used my existing reflector and had a noticeable lighting increase in my tank - fewer dark corners. My tank is a 90g with center brace with a single 400w mh over the center.
    If anyone tried this let me know how it turns out

    If you are talking about the plastic reflective film called mylar, be very careful. With the heat a MH generates your plastic film could catch fire. One member on here used it as a reflector and it started a fire in his canopy.

    As Ak mentioned, it is called Mylar. I too used to use it in my canopy. When I was using 250w MH lights, it was o.k. but now that I have been using 400w lights, the mylar dries out and starts to crack and fall apart in pieces. If I were you, I wouldn't use it. It IS indeed a potential for fire down the road. The pieces fall onto the reflectors and even in the water. I have since removed it from my canopy.

    So far what i have done is put in my canopy but excluded the section between the reflector and the canopy, so the surronding area does get warm but not excessively hot. Also the fact that i used a special trim spray glue in a can. So far no side effects but i will definetly watch out for anything suspicous and if i have any doubts i will quickly remove it.

    Pardon a really stupid question....can aluminum foil (aka tin-foil) be used? If it can survive in an oven at 450F...
    And it would be a lot cheaper.

    I tried that once, the problem is that after time it will crumble and flake from salt splash/spray.

    Crazy,
    It doesn't happen over night, but it does dry out soon enough.
