I'm fish-sitting a mate's aquarium and using it to get all the cycling media
ready for my own new tank which arrives in a few days. The new one is 48" x
18" x 22" (US 75 gal), has 3 tubes. I aspire to it being a quite densely
planted tank. Here is what the guy in the shop sold me for lighting:

1 x 36w standard white tube
1 x 36w Super Daylight 100% Actinic 03 Blue tube
1 x 36w High Intensity 10,000K High-Intensity Purified Super Daylight tube

I could change them when I pick up the tank in a few days. Any suggestions
much appreciated.
