My aquarium is an Eheim Vivaline 240 litre. Dimensions are 1200x400x500mm (length, width, depth) and water depth averages about 410mm allowing for gravel, etc. The current lighting is two Narva LT 39W T5 HQ 865 tubes (850mm, rated at 3300 lumens each) on for 9.5 hours per day. I recently installed a CO2Art pressurized CO2 system and dose daily with EI ferts. Plants are mostly various species of Vallis, Crypts, Echinodorus and Ludwigia and are now growing well and the fish are fine.
I’m now looking to replace the existing lighting with LEDs and a controller/remote and like the look of the Zetlight Lancia ZP4000 system, but I’m not sure how many lightbars and/or what size to use. Bearing in mind that I want to retain the existing hood and that the current T5 lighting gives approximately 6600 lumens, I could:
1) Replace the two 850mm tubes with two of the ZP400-895 lightbars (34W, 2,900 lumens each), which should mount in the existing fittings. This would give 5800 lumens of lighting;
2) Remove the old lighting fittings and mount two ZP4000-1047 lightbars (42W, 3500 lumens each, 7000 lumens for two);
3) Remove the old lighting fittings and mount two ZP4000-1200 lightbars (46W, 4100 lumens each, 8200 lumens for two).
Although using the existing light fittings would be easier, mounting the longer lightbars onto the edge of the hood shouldn’t be too difficult.
So depending on the chosen solution I could end up with 5800, 7000 or 8200 (LED) lumens instead of the existing 6600 (T5) lumens.
My guess is that the light output of two of the 34W lightbars would be insufficient for my setup and that I should opt for a pair of the 42W or 46W lightbars, but which one?
Any advice before I spend around £300 on the lightbars, receivers and controller/remote would be gratefully received.
