So do I!!. You are convincing me!!!

For the T5 experts: Which do you think are the best for me:

Two T5 39w or,
Two VHO 95w ??

First of all, if you like the 450nm PCs, those are blue, and so if you want that same color output, not actinic, then T5s are the best option. ME personally, I like a bit of both... one actinic and one blue+... that would look great.

What type of 14,000K are you using though? 400watts on a 65g? You might consider scaling that back to a 250wattDE or something. 400watt halide paired with 2x39wattT5s is more light than just about any coral I know of would even want. What do you have, a 5 hour photoperiod? Either that, or you are running a very crappy reflector, ballast, or bulb setup that most 250wattDEs could outdo.

If you tell me what type of halide bulb you are using, I can suggest more. Some 14,000Ks are much different than others. A UShio 14,000K for instance, has loads of actinic already in its output, and so only needs blue bulbs for supplimentation (the only thing it lacks).

Do you mean that the VHO is heater than the T5?

My halide is Hamilton.

In the other hand I really like 420nm color not 450. As I have enough light as you could see, I want actinics. I used 250 watts, 14000K hamilton, but the tank looked like very "blue" for me. Now with 400 watts is white or yellow for me, I liked to give a purple tone to the water.

Lol, no. T5s are better IMO.

Stacking up one VHO to one T5 isnt quite fair though. I would use dual UVL super actinic T5s for every one VHO run normally.

Sorry I am Venezuelan; what do you mean with "IMO"?

 

[hahnmeister]

In My opinion...

 

[CarlosS]

Of course!!

 

[CarlosS]

Well..

I think that the VHO won the competence. Anybody else wants to vote?
