I need advice on which MH bulb to choose

[blueheaven]

Hi guys, i am getting my new tank soon and has already started planning on the lighting system.

I have shortlisted some bulbs in which i will choose one to use

I do not really emphasize on the growth rate of the corals but more importantly on their colouration. Best if can get a bulb on the bluer side but not too blue.

The bulbs are as follows:

1)250watt XM DE 20K

2)250watt Coravue DE 20K

3)250watt Radium 20K

4)250watt BLV 20K

What about Aqualine and Megachrome? Pretty good bulds I would say. I'm using both of them (150 Watts). Nice crisp white.

IMO, my BLV 20k is too blue.. everything looks blue.. can hardly tell the colours apart anymore.. i rather have a 10k....

was initially thinking of aqualine but i found it to be too blue.

but from the reviews at RC, the AB is quite good.

so what do you guys think?

Aqualine (AB) too blue? Unless you are talking about the 20k? THe 10 k is nice white, the 20k I have no experience. (All my experience is with 150w)
