MH vs t5ho
 

i am running 6 t5ho over my 80 gal and have a chance to swap to 2 400w MH
/ ballasts and reflectors should i or not and don't really know the ups and downs.also gonna up grade to a 180+gal in the future
i think it has 15000k bulbs
don't know much yet sorry all i know they are worth a pretty penny

Depends, what are you planning on keeping ? What is the depth of your tank (and future)?For right now it sounds like over kill. I think 250's would be a better choice and a lot less power consumption. I seem to be getting big on power consumption lately:confused: Good deals always come up for stuff if your looking. I shut up now until more info :)

my current tank is 18 high and the one ill build will be 24 high and of corse i have sps right now

Then I think the 400's would be to much for what you need. Not happy with T5's ? I'm going to switch from MH's to T5's when I up-grade

+1 Heat would also be an issue I think

best choice i ever made!

what switching to MH???? and i guess i could just run 1 for now till i upgrade

I ran 2 400W MH over the corner tank I used to have set up. I loved them. At that time I ran 20K radiums. I'm using one now with a 10,000K over a 65 Gal tank I have set up. Other bulb will be 250W but everthing is temporary till I get my corner tank set up again. A chiller is pretty handy when you use 400"s.

No switching from MH to T-5. Granted i do have a nano tank. the temperature fluctuations and the evaporation was getting tricky to deal with. I like thae fact that you can fine tune the colour of the lighting with t-5. IMO one isn't really better than the other, its more personal preference.

the ballasts are vue technology
