I’ve only ever used T5 as supplemental to MH, but now I’m interested in using them exclusively on a frag tag. The tank is 120x60x38cm (~4’x2’x14”) with a water depth of about 30cm (12”), and I want to get ~60 PAR at that depth evenly throughout the footprint of the tank. I want to mount the lights about 60cm (24”) above the tank. How many bulbs, approximately, would I need to achieve this? Guesstimates are fine, I’m just wondering if I should order a 4, 6, or 8 bulb fixture and then play around with the bulb quantity a bit from there. Thank you all!
