Low/Medium light recommendations for 75G

I'm looking for lighting recommendations for a 75G tank (48" by 18" by 21" high). Based on my calculations (using the various graphs on this forum) it seems like a fixture with 2 T5NO bulbs with a very good reflector would suffice or possibly a single T5HO bulb fixture with a good reflector. Unfortunately both of these don't seem to exist. So I'm wondering what people would recommend for lighting this tank in order to achieve low to medium light (in order to avoid CO2 and minimize algae problems).

Thanks,
Harry

you might be able to get away with a cheaper T5HO light fixture since usually cheaper fixtures have not as efficient ballasts.

The Odyssea 48" Dual T5 should work just fine for only $60. I have the 24" version over my 29 gallon and it's the best light fixture ive ever owned!

The sun blaster nano reflector is insanely good for the price. Comes with a t5ho bulb too and you can daisy chain more if you want more light.

I am quite curious about these, one T5HO only.

They say "This revolutionary reflector can increase lumen availability by as much as 300% and is now included"

Wondering if someone ever did PAR rating of one of those.

I primarily use 3 20watt cfl bulbs with good results on my 75, and its cheap. 4 would be better, though.

I can grow a carpet, stems, etc no problem. With 2 T5NO I don't think I could get stems to grow nicely or a carpet

There are some older tank threads here with that light and from the pictures that reflector looks insanely good. The beauty of them though is that you can daisy chain up to 8 and have one power plug.

I've asked them a couple of questions via email, but I keep getting very short (ie: 3 words) replies that don't help me much. So I'm not too impressed with them although I know lots of people are. I'll keep asking them questions until I get some answers

Thanks,
Harry

The problem with using CFL would be finding a nice looking (ie: living room and wife approved) hood for a 75G.

It looks like these would have to be mounted/attached to something. I'm hoping for something that can sit on the glass cover of the tank (ie: standard aquarium T5 light shape).

Thanks,
Harry

Wouldn't that put me way above low/medium lighting?

See if you can get 2 of these in Canada.

According to Hoppy's chart, few inches about the water surface, you should get from high medium to low medium lighting with these.
