guys,
i am living in KK, Sabah.
my LFS and local lighting & fitting shop are not selling any T5 High Output (HO) at all. I am force to use T5 Normal Output...i know the lumin is not enough per tube but what if i increase the number of T5 NO? does the lumin add up?
current intended setup...:
65 Gallon tank, 2 ft deep tank.
1) 6 x T5 NO 21w Daylight 6500K with i think 1900lm per tube. 6 x 21w = 126w
2) 3 x T8 20 w~ consist of Aqua-Glo 18000k, Power-Glo 18000K and daylight 6500k. 3 x 20w = 60w
total watt: 186w = 2.86w per gallon. i guess is a fairly good coverage for my planted tank...but....
how about lumin? can i addup also? i know HO lumin is double per tube, so... i thot of having two T5 NO to become one T5 HO...am i correct to think like that?
actually currently, i am using 4 x T5 NO 21w and 3 T8 20W. my plants are pearling at the 1.5 ft above...not the bottom .5 ft... so...i wanted to add 2 more T5 NO... does the lumin addup?
pls advise.
i hv no choice but to settle with a lot of T5NO since i am living in small city...la... pple do raise saltwater fish, but mostly using MH... some hv to travel to KL or singapore to get their T5 HO.
thx...
no intension to use MH as the tank location and setup not suitable. besides, i dun hv chiller ....

I don't know, but I just have the notion that a normal T5 and FL have low penetration into the water. It could reach 1.5ft well for the plant, but 2ft I guess it's a little too deep.
It's about some of the spectrum of the lights that need to reach out to the plants which they could utilise.
PL tube will have better penetration rate. Even better is MH light.
