    Hi Guys!

    So its been a while since I've documented my tank, but it's been cyclying for a good few months now, just to be on the safe side. I've started stocking the tank by very slowly.

    It's a Juwel 260. So dimensions are 1200x650x450. The tank has 2x54w T5's as standard, but they kak expensive to replace (around R400 each). So, I'm going DIY.

    I was thinking of building a Light Unit for it, but I was reading through the forums and spacing and heat issues etc seem to be common. So I've decided to build a custom hood to fit over the entire tank.

    The setup will be as follows :

    4 x 54w T5's : 2 x Blue, 2 x white, moonlight LED's
    4 x 220v Fans

    So the questions I have for the experts are :

    1 - Should I make it out of Normal Plywood with a few coats of sealer, Marine PlyWood or Aluminium?
    2 - I'm thinking of painting the inside white, and getting individual reflectors also. What paint would be best? Comments / suggestions?
    3 - Is it ok to use a clear perspex or glass panel as a splashguard?

    Any help / advice would be greatly appreciated.

    I'll be documenting the build and post pics of the design soon.

    Thanks!

    Ok so here's a quick draft of the hood. I know the bulbs etc are not to scale, but it was my first time using sketchup. Any comments? suggestions? the portion thats 167.8mm is going to be part of the hood that opens. Oh and I forgot to add in reflectors - imagine them there... :lol:

    1. I would go for aluminium as it is a material that can be cooled fast.
    2. Great idea to paint it whie and use individual reflectors. How about an oil paint like Velvaglo?
    3.Yes, the thinnest perspex you can get, and make sure it wiped atleast once a week.

    Its lookin good rajah - how is the hood comin along - I dont think you will need 4 fans - i would use 2 fans - I sucking in air and another blowing out air - you might find 4 fans a little noisy aswell. You could connect the fans to a thermostat to only come on if the hood reaches a certain temp.

    thanks durleo

    I eventually decided to go with 12mm Plywood. A buddy of mine has a paint factory, so I got some white acrylic waterproofing paint made. Gave it a good paint. seems to be pretty good. I'm waiting on the alanod though. can't find reflectors at a reasonable price in dbn. I also only put two fans in. I realised that 4 would be a slight overkill.

    will post pics soon.

    I just noticed the width of your tank and hood dont match up.
    450mm in tank vs 335.6mm in the drawing.
    Am i missing something?

    Hi butcherman.

    I forgot to mention that the tank has a bow front. So the end points are approximately 330, with the front centre (widest point) being 450. The additional 120mm, i've decided not to cover with the hood, for now. But I have included the front panel :)
