is this too much lighting for my tank?
hello, i have been doing alot of research on lighting and what to use for planted aquariums. So i have an Odyssea t5 4bulbs 48" system on my 55 gallon tank.. Tank is 21 inches high and the Odyssea light system is mounted to my tank with the mounting brackets it came with. so its mounted about 4 inches off the tank. so with about 2-3 inches of flourite gravel i would say the light is about 22-23 inches from surface of gravel. i have 2 6500k t5 HO bulbs and 2 5000k t5 HO bulbs. i run 2 at a time. 2 from 7am-2pm, and the other 2 from noon-8pm. so thats 11hrs of lights being on, with 2 hrs of all 4 bulbs being on at noon for (high noon type lighting). my question is, is this too much light for my tank?? i have micro swords, 4 amazon swords, rotala, crypts, anubius, water wisteria, blyxa japonica, s.repens. i use EI dry ferts and i use seachem excel because i dont want to run a co2 system. i have been trying to understand par levels, but i cant seem to find any charts that make sense. i know the watt per gallon rule goes out the window with t5 bulbs. so really not looking for wpg but just wondering what is my possible par level?
