lighting question

[ryan27272]

ok i bought a light for my 20 long reef from another board member recently and im happy with it but i have a chance to get some very colorful LPS and a few SPS from a friend for free. so i was wondering if anyone had any suggestions on some add-ons to light i have. its a 130watt compact. now the tank is only 30 x 12 x 12 so not alot room on top. love to keep the light i have so is there anything i can just add that will fit in the room i have?
thanks

2x65W PCs would probably do fine for most SPS in that size tank if the high light loving ones are kept close to the top (top 1/3). They may not color up as nicely as with better lighting, but they should do reasonably well. At least well enough to experiment and then add new lighting in the future if you think they need it.
