T5 lighting?

[marinegeek101]

Hi,
I have T5 lighting for my aquarium and its pretty far from my aquarium. I would say 6-8 inchs. Should it be completely on top of the aquarium or is this good. My aquarium is 32" by 19 1/2 ".

i would lower it if you have high light demanding corals!!! if not, it really doesn't matter..what corals are you keeping???

I think that that is fine, there really isn't a way to lower them unless you hang them and let me tell you that thats a pain!

 

[Scooterman]

That is about the right height if it is like that in the photos!

 

[ronj]

i think his are higher than the ones in the pic..they "appear" to be about 3" above the water in the pic

so do T5's run um h ow do I put this? Can my husband install them in an existing canopy w/o a fan? it looks like T5's need to be a little higher than power compacts. Sheesh if I knew I was actually going to need physics I would have paid more attention in class!

I run mine 6" above the water level and have no problem with my sps......except for the power outtage!:evil:

just saw that....closer the better

they do put off heat.... my fixture has a small fan at the end to pull the warm air outta the sealed unit.... but if you have a large enought opening win a vent the air (hot) would find its way out

ok, thank you

 

[marinegeek101]

cool, thanks alot

How much watt /litre you use for sps?

How much watt /litre you use for sps?

I using 4 54 watt tubes over a 65. I have the sps in the upper half of the tank but some like it on the bottom.

 

[marinegeek101]

sweet thanks as tasos asked how many watt/ gallon do you use for Sps?

 

[tasos]

I have 6 54 T5 tubes over a 5 feet long(150 cm) nearlly 100G JUWEL aquarium, and it seems to my eyes to much lighting!!What is the bulb spectrum that you use?Mine are 3 arccadia daylight, 2 arcadia actinic and one sylvania ~6500K that makes tha ''sun'' effect...


PS:sorry for the hijacking!!!!

I run a 5 x 39W unit over my 40 gallon and have sps in the top half. I run a relativley simple system but am still able to get .5 inch+ growth a month outta my sps. I imagine I could do a bit better if I had a fuge/sump/ca reactor/phos reactor etc.
My light unit is presently 5 inches off the water on some custom stands but I plan on using a hanging system so I can them down to about 1 inch off the water. I bet I will see an increase in growth when I do.

Peace

Your eyes can't be used to determine how much light is required, it may seem super bright but the light intensity required by corals into the depts of water is usually way higher than what we put on our tanks, when comparing to the suns natural light.

You are right!!
