Hi all,
Just after a bit of advice really on lighting requirements for my new setup. I'll start with my current setup.
Tank: 36"x15"x15" 120L
CO2: Pressurised (Fire extinguisher) on 3 hours before lights on
Lighting: Arcadia Twin 39w controller (1x Original Tropical, 1x Plant Pro tubes) on 6 hours/day, about 5cm from water surface in the tank hood with reflectors.
Ferts: dosing 15ml/day (APF All in One Plant Nutrition)
Planting: medium to heavy
So I'm upgrading my tank to an optiwhite, rimless/brace-less 48"x16"x16" I've nearly finished building my new cabinet (just need to finish painting it) and want to start looking at building a diy luminaire. I would like to use my existing twin 39w controller but I'm not quite sure if I need to add more light and how far away I should hang the luminaire from the water surface.
Obviously if I stick with the twin 39w they will be a fair bit further away from the water, plus the extra inch of water. I assume there would be less light getting to the bottom of the tank.
So would I need extra light to compensate for the extra height and how much extra? Also what sort of hanging height should I be looking at? So I can work out how high my brackets need to be.
I've attached some drawings to show what I'm thinking of with some possible lighting configurations. Hope fully they are pretty self explanatory.
Thanks,
Richard
