I have decided to build a canopy to house my AI Primes and LET T5 kit for my white Reefer 250. I would prefer it to be either a white or black canopy. I am a total noob when it comes to anything DIY, so could someone please recommend the type of material the canopy should be made? I have yet to decide if the canopy will go to the rim of the tank, or if I will leave a gap in between the canopy and tank, so any advice on that would be appreciated as well :)
