thanks guys,
corals have had a hard time with all the moves
the leather the ocellaris hang around decided it didn't like the move and disintegrated in the centre
so i fragged it
was a pity it had a 30cm disc on it when extended
big thanks to dan in chch who sent me up another double 250w halide with 4 t5's
so once corals get used to it i should see some massive growth
