Ok there are a lot of different opinions in an "increase" in light. no you are running 1 PC, so if you upgrade to say 4 T5's then you will get a little more light intensity but it will be more evenly balanced across the tank so it will look a lot brighter.
the only way to get a "Large" increase in usable light is to make the jump to MH as they are basically in a class of there own.
PC's T5's and VHO's are all in the same class of lighting. PC's are about 10% more output then VHO and T5's are a little more than PC's.
Some dumb info in case people didn't know a PC is actually a T4 bulb and inherently more intense than a T5, but because of the design not as much usable light makes it to the tank. So one day some one is going to design a single tube PC and start calling it a T4 and it will be the "next best and greatest" lighting product
anyhow with a 18" deep tank depending on the room you have under your hood you could through a couple of 175 watt MH in there (or 250's) or even 150HQI's and you will get a very large increase in your lighting, but from what you have said you want to keep you don't need that much light. sebae aside (as I have had a bubble tip but not that) everything will be happed under any lighting that has been mentioned above so the cheapest option would be to buy another PC tube or two) personally I would buy 1, 10000K PC and 1 actinic VHO and set them up so your VHO is in the middle, but having said that if it turns out your Sabae would like lots of light you could get away with one 250 watt MH in the middle and some actinic lighting of some sort, or if it doesn't need that much light and you can find a screaming deal on a T5 set up that will give you a minimum of 3 tubes (5 would be cool as you could do 10K actinic 10K actinic 10K) this is the benefit of T5, not that they are so much more powerfull, but rather because they are small you can stuff a lot under the hood.
hope this helps.
Steve
