Have just upgraded from a 1.2 x 0.5 tank to a 1.5 x 0.6. I have a arcadia metal hallide lamp with 2 x 250w lamps (20k aquamedic). Anyone running anything similar on a 5ft? and what results have you had.

Have been thinking of changing to 2 x 250w running luminarc refelctors or adding some t5 tubes to add some more light. But if I am not going to see any huge improvement wont do it as do like the look of the arcadia unit

Keeping sps and lps corals

Mine is 1.2*.6*.6 next year i am upgrading to a 1.5*.9*.6 when i do this i will keep my existing 2*150 aracdia and add 8* T5's

Just some food for thought

ive got the arcadia 3, 2x250 with 2x t8 actinics. im pretty happy at the moment with how is going on my 5 ft. definitely is less light at the ends which is where i tend to put more lps. i like the varience of light thru the tank, that could change tho as i increase sps

I have 3 x 250w mh and a couple of blue T5's on my tank, just a bit over 5 foot. I couldn't see me going with less light than that
