T5 ?

I have a 35 hex with what I thought was good enough lighting. My question is what wattage and volts would I need. I was told about a 150 or 200 M.h. but nothing about a T5. I want to do a reef tank.

Just look at the size that fits the tank this will give you the watts. Make sure you are looking at the HO T5's and get good reflectors.

for an odd shape a pendent mh or hang on side mh would be good there are 2 types of t5 normal output zoomed makes a real thin model but it is useless for coral tek and current usa makes a ho t5 that is a harder driven bulb that can be used for coral i am a t5 fan but i think you would be better with mh otherwise you will be having bulbs hang over the side when you stack a bunch of them on

Look at the top of the tank. What is the lenth across the top? This is the lenth of the T-5 lights you want to get. When shopping for T-5 lights, look or ask the place you are dealing with, if the reflectors behind the T-5 bulbs are one reflector for the whole light, or indivial reflectors, bulbs with a indivial reflectors are better. It make better use of the light and sends more of the light down to the tank.
If you are thinking about Metal Halides, then a 150 or 175 watt pendant type light will work well above the tank. (these hang from the ceiling. I would consider a 12, 13 or 14K rated bulb, this will give just a hint of blue to help with the look of the tank.

If you get a pendant and hang it from the ceiling you will hang it so it would be about 12 inches from the top of the tank.This will give plenty of room to feed the fish, and work on the tank without burning your arm. This will also be enough room for a fan to blow the heat away from the tank. Just place a fan so it blows across the top of the tank..


That is the bell pendant that I used over my 29, they make better looking pendants now. Just look for about a 150 or 175watt. Like stated before I would use a 12, 13 or 14K bulb.
The fan is an example. I found it at Lowes last summer. I know this time of year it is hard to find any fans much less a choice. But this gives you an idea.

Doing corals your lighting should be about 5-6 watts/gallon (I think that's right)....so it would be like 210 watts or so when all is said and done.
