im looking at a aquaticlife t5 fixture on marinedepot.com. my tank is 36 inches wide and i believe 26 inches deep. 65 gallon. right now just fish only with live rock but eventually want coral. ive heard its not a particularly typical size for a coral tank because it is so deep. will these lights do the job in the beginning? i am on somewhat on a budget. and bulb wise i see there are different colors ; blue plus, coral plus, purple etc... should i have 1 and 1 or 2 of the same? any info will help thanks
