That is what I have on my 55gal.. I have 2x250watt XM 10k bulbs along with 2x55 actinic Catalina PC
bulbs.. I think that It is a nice amount of light and IMO
not too much.. I did alot of research on MH
lights before my purchase and found that Anwhere from 175w-250w would be acceptable.. I chose the 250s purely due to the fact that I will have a much bigger tank and would be able to also use them on that tank.. So IMO
I'd say if the price is right what are you waiting for.. FWIW
i paid 155.00 +35.00 s/h for my 2x250w without bulbs.. Bulds were another 65.00ea for the XM bulbs..
