Effective lighting depth
At what depth does T5 lighting loose its optimal power? i have two 48 watt t5 fixtures above a 29gal (18in tall) and was hoping someone knows how deep those lights are good for so when i decide to upgrade to a 45 tall(24in tall) i will know if i need something more powerfull like halide
thanks in advance |

That's hard to say for sure. If the fixtures have an individual reflector for each bulb, 24" should be fine, though.

At 18" you should be able to keep just about anything under T5.

Thats pretty much what ive been told as well.. the lights did not have a reflector for each bulb so i took out the metal reflectors and installed glass mirrors instead.. man that made it so much brighter! good to know that i wont "need" to upgrade my lights for now.

even know it looks brighter with mirrors it more then likely is not.... And will proudce more heat then a light reflecter ... For a mirror to reflect light it travel's past the glass twice and u lose your parwatts. I would look into some other method to reflect.

i dont know anything about polished aluminum as far as refleciting
i know aluminum foil is even worse then mirror the heat is 3x as much..... i know mylar is 98% reflective with very little heat but i dont think i would use it in a light fixture lol..... all the t-5 i have ever used had a good fixture so never looked into what would work the only reason i know about the mirrors & foil is i did research for indoor green house and what was best to use for the wall's and i ended up with mylar im sure u can do a search and find out what lighting hood's use for a refictent i allso happen to know that PL lighting make hood's to reflect what color temp ( k ) you wish to reflect hydrofarm also dose but not custem like pl....... |

I think a good T5 setup would be fine for a 90g. Check the Aquactinics brand, or look in the equipment forum for more information.

As far as how many, i will most likely go with 6 overdriven T5's over my 90 and i may not run all 6 for the entire lighting cycle each day. I'm most likely going to go with overdrivenT5's on my 90 build.
