[Albz]

So i got my new fusion 30l ext tank. And i got s really good deal a ati t5 fixture its a 6bulb 36". The tank is 36x15x13h . So on a 13height tank how high should this fixture be? Planning to have sps and lps.

That's a ton of light for that tank. I would start at 14" or so and you'll have a lot of light bleed
