kevin, its a 180 tank. i also have a 4x2x15" sump underneath with about 30g in it.
greenterra, i know what you mean about the blue, i wish i had painted it black now. 3-4 months ago it was a marine reef, i'm still running the metal halides, love the shimmer but i think they are a bit bright for freshwater.
ccebr, i'm from torbay in south devon. where you from ?
