Unusual Lighting Questions
1) I am setting up another 29 gallon tank. I have a 2 bulb HO T5 light fixture which would obviously put me in the high light zone. I would prefer to keep this tank at low/medium light. This fixture does not work with one bulb removed.
Would blocking the cover under 1 of the bulbs be alright to bring me down to a low light level? I was thinking about simply painting half the cover under the bulbs black. Or even applying duct tape over half the cover to block the light produced by that 1 bulb. (By cover I mean the protective plastic strip under the tubes) I realize this would probably increase the heat levels under the bulbs.
2) I am currently using a cheap, 24", T8, flourescent, one bulb light fixture that does not have a reflector (other than white plastic) for my current 29 gallon tank. The tank is heavily planted and the plants do OK but nothing special.
I was wondering if adding a thin piece of sheet metal above the light would help increase the reflection and the light being delivered to the plantst? Maybe something even as cheap as aluminum foil above the light might help?
What do you guys think? Thanks in advance for any replies.
On the T5 issue, I wold suggest a new fixture. I would be concerned over wasting two tubes (which are not cheap), energy, etc. One thing I have often wondered is if a burnt out tube in one would still allow the other tube to be lit? I know you can't remove a tube, but if it was in but didn't light... ?
I did this with foil tape. I has worked well for me. You can get a pretty large thick roll at any hardware store. Bought mine Lowes. Its much like duck tape, but foil.
Thanks for the responses.
I think I will try the aluminum foil or the foil tape on the one light and see what happens. I am currently using nothing but Life Glo tubes as they are the only ones I have tried that do not give off a purplish hue.
Hmmm-I like the idea of having one burnt out bulb and 1 good bulb for the HO T5. I can't see why that wouldn't work.
