hello i have seen a light unit i could make which has 6 x 39watt t5HO light tubes would this be over kill ? the times ( ever 2 tubes are run on a plug so 3 plugs in all )


8-11 two bulbs on one plant grow one sun tube
11-1 all tubes on miday burst
1-6 2 or 4 tubes on not sure
6-7:30 two moon light tubes or might try to wire just one up and run the other light on a different plug.

if i did run 234 watts on this size tank (30"x15"x15") how many bbs would i need to stop algie ? and what are the out come of this much light and if you would change the timeing what would you have it as ?

Overkill for sure, in my view.

Your CO2, circulation and nutrient management would all need to be absolutely spot on to prevent algae issues.

We're talking a razor edge line between uber-fast plant growth and nightmarish algae trouble.

If you fancy a challenge then go for it!

Personally I'd stick with 2 x 39w over that size tank. You'll still be able to grow any plant you wish. And your energy consumption and risk of algae will be a much much lower.

Will all due respect to the APC member I doubt it is feasable to keep any planted aquarium long-term algae-free with that much light (assuming all lamps on), unless the photoperiod is limited. For me it is simply a waste of energy and resources; but each to their own.

Agree with George, on my 120 liter tank I have been running with 144w of light for testing stem growth and the margin for error is very little, trying to keep CO2 at the right levels is the challenge. So i might just reduce it back to 96w again :)

yep, major overkill, for all the reasons Geroge states.
I can grow anything with 72w over 160l and am currently running just 48w and getting good growth.
