Advice on my light conditions
I have a 140 Gallon planted tank. Considering the rule of the thumb. I've lit up the tank with 432 watts (T5 - 54watts 6500k X 4 nos and T5 - 54 watts 12000k x 4 nos, good reflectors in place. The nett result is I have 3.09 watts per gallon. Which I presume is in the borderline of Medium range to High range.
less than 1wpg -> unacceptable for plants
1 -2 wpg -> low light to medium low light
2-3 wpg-> medium light to medium high light
3wpg+ -> high light.
Glosso - Light requirements are 3+ wpg or Greater than 1 watt per liter
Mine is 530 liters full.
My tank depth is 30 inches and the light are on the rim. Friends from this forum have felt that is very high light..
P.s - No algae problems, Runs with proper Co2 system. Off late 5% of glosso leaves turning yellow with transparent dots / holes. water temp 80-83. No chiller in use.
