Half your luck having the week off tdj5, i went the sand option as well but i'm not sure if its going to be as bright as i would like it to be, i got white sand from my local landscaping yard, nice and cheap but dirty and slow process atm cleaning it lol.
I'm hoping the lighting will make it a lot more whiter, as to which light/lights i'm going for id like some suggestions as i don't know a lot when it comes to picking but i was leaning towards to options,
The 1st being a DIY light off ebay http://www.ebay.com.au/itm/1-30M-SMD-5050-RGB-LED-Strip-Light-Flexible-Lighting-Kit-12V-DIY-Power-Adapter-/121947389443?var=&hash=item1c64a17e03:m:m-8h9g05HPbb6Eh-ebRZA0w
or the 2nd being 2 of them either http://www.aquaholicsonline.com.au/beamswork-ea-120-led-aquarium-light-120cm-4ft-moonlight-10-000k.html or http://www.aquaholicsonline.com.au/beamswork-bright-hi-lumen-120-white-blue-moonlight-led-aquarium-light.html
Sorry for all the questions and links, any suggestions or other lights i should look at or feedback will be greatly appreciated
Cheers Jimps
