sun tek t5ho
 

I have a 150 gallon 5'x2'x2' running co2 will this light be considered high light or medium.It is a sun tek with 6 54watt t5ho.Im wanting to up my lighting so the reds will pop in the plants.Thanks in advance.

Definitely very high light, you will need CO2 and maybe see if it will allow you to run just 4 bulbs.

Thanks for the reply I am running co2 and the lights have two switches you can run four,two or all six.I figured I would run four most of the time with a two hour period of all six.So would four be considered high light also.

i run that fixture on my 75 gallon. i run 2 bulbs for a 9 hour photoperiod. i run the other 4 bulbs for 3 hours in the middle. fixture is hung 10 inches over my tank.. yeah its a lot of light
bulb selection will also play a factor in this
