View Full Version : Adding actinics on a MH set up

My MH fixture is at the top of the hood, which is about 12" from the waterline. I am planning of adding some T5 actinic. How do you guys with similar set up mount the T5?

My tank is 48"x24"x24".

I can mount it lower in the middle of the hood, but that would block the MH light path.

If I push it to the sides, there isn't any corals near the glass.

What if I mount it near the glass at an angle pointing towards the corals? Would T5's reflector work well shining at an angle?

I can mount it beside the MH at 12" above water line, would it be too far off?

Existing light is 2x150W MH, I am thinking of adding 2 tubes, would that make a difference in look at all? As I can't squeeze too many tubes in there.

Thank you for reading.

Navyblue,

I had the same problem with my 95 wave tank, with similar dimensions to yours.

It is a strange shape which limited my ability to place them in the "ideal" location without interfering with my halides.

To my surprise, when I installed them the light filled the entire tank, despite the "angle of attack". I know the MH bulbs have a more focussed beam, but I think you will be pleasantly surprised with the T5s. They will throw their light far and wide.

Thanks Dave.

So how did you actually fixed them? Just mount them near the front glass nearer to the water surface? Did you tilt the light so that they points to the centre of the tank?

i mounted mine on the underside of the wooden canopy and like lemadl stated they did have a good casting of light

I had a similar issue in that my 75g is mounted in the wall under the stairs which left me very little room for lights. For a year I ran with two 150w MH Aquamedic pendants with Phoenix 14k bulbs and was relatively happy. I started to miss my dusk/dawn and wanted the colors to pop a little more. After contacting Reefgeek, I ordered a Tek T5 54w two bulb ready retrofit with an ATI Blue + and a UVL Super Actinic. I installed the retrofit toward the forward edge of the tank and angled the reflectors a little toward the back. The coverage is great and the colors are fantastic. As a bonus, my growth rates have improved.

I have a canopy w/ 14" of inside clearance, I have 3x250 mh's and 3x5' t5's. I just mounted the t5's at the top of the canopy: 2 in front of the mh's and 1 behind them, it works great

I guess it worked no matter how I mount it?

My most convenient way of mounting seems to be mounting it at the same level as the MH, may be 1 tube in front and another at the back, as it will not interfere me from putting my hands in the tank.

Any objection? :D

Thanks Jag1979 for the pictures. What tubes are those that you are using?

I have problem getting actinic tubes here. I wonder if ATI's "Blue Plus" will do fine for fluorescent purpose? Also anyone has any information regarding "Aqualight Coral Blue" tubes? Those are the closest to actinic that I can find here.

I wonder if anyone of you can help me save a couple of minutes. :D

I am pretty busy lately. I got myself 2 T5 tubes, ballast, reflectors and wiring. After an hour of hooking up, when firing up, the tube would only blink once and cease to light up. I haven't try the other tube. I could figure out what's wrong with it after an hour of fiddling or so but may be your experience could make my life a little easier. :D Does it sounds like bad ballast? or wrong wiring?

Thanks a heap. :)

when that happen, usually that mean you have a bad ballast ... the same thing happen to me. But to be sure try other tubes, it could also be bad contact.

I would think it was bad wiring. Go over the wiring scheme to double check.

what bulbs and reflectors and ballast did you end up getting, navyblue?

Navyblue

I got the Aqualight Coral Blue, Tridonic Atco ballast, and the so called "M" shaped reflector.

I guess I'll try the other tubes after I got more wiring, and contact the seller too. Will let you guys know again.

Thanks guys, btw this is the first time I am doing this sort of thing. :D

The answer was the ballast will only fire when both tubes are connected. :D

I'll post a picture of the tank and the set up after I finish hooking them up on the tank.

Here it goes. In the end, I mounted the T5s on top of the canopy with the MH, one in front and another behind.

Here are how the tank looks like. All the pictures below has identical exposure and white balance (6500K) for comparison purpose. Please pardon me for the diatoms. :D

2 x 150W DE MH (10000K BLV at the left and 7000K Astralux) only
