Lighting recommendations for a 90g (to add VHO's or not)

[RyanH]

I would like some lighting recommendations for my new 90g. My current situation is as follows:

2 x 175W MH (Hamilton 10000K)

2 x 55W PC actinic

The MH bulbs are 7" above the water surface and the water column (with DSB) is about 19" deep. I would like the option of keeping clams and SPS. Is this enough light?

If not, I have an Ice Cap 660 ballast that I could use to supplement the current setup (using 46.5" bulbs). If you were going to add the VHO's, how many would you add and what color combinations? I could always switch the PC's from actinic to regular bulbs too. Anyone with exerience with this would be very much appreciated. Thanks.

It is probably enough light, but I would go with dual 250s, if you can. Rarely do you find somebody who wishes they had less light.

I wish I could go with bigger MH (probably 400's if I could), but right now I have the 175's so I have to use them. Just trying to figure out if I need to add the VHO's, or I will use them on another tank. If anyone has any input regarding the VHO's please let me know. Thanks.

Hi Ryan. I'd go with as much light as you can afford to run. If you can add all 4 bulbs then go for it.
