Hoppy, Thanks for responding
I just looked at the new charts and wow, there's a lot more to consider. My unit's not listed there and I'm not sure what the reflectors look like on those units.
I'm using an Aquaticlife 4x36" T5HO
It has worked reliably and their customer service is pretty good, btw.
You can see the PAR performance in their user manual (Page 4/5): http://www.aquaticlife.com/sites/def...ets/420036.pdf
I've got 2 of the original Aquaticlife 6000K
bulbs (8 months old) and 2 Zoo Med Ultra Sun Trichromatic Super Daylight
Bulbs 6500K (http://www.amazon.com/gp/product/B00...ms_ohs_product
). (7 months old)
The reflectors are 1/2 parabolic but each bulb has a reflector.
The unit is 9" across, the bulbs are evenly spaced and 8" apart.
I'm starting to think to try this:
- Add another hour of burst for 4 hours of 156W, wait a week.
- If that doesn't work go back to 3 hours burst, and drop the light 1" and wait a week.
- If that doesn't work, add another hour of burst, and wait a week.
