Thinking about new lights

[coach_z]

changing the k rating can eliminate your yellow problem. i feel that you will get the best results by changing your bulb and adding co2.

Ok, can I buy a bulb at a petsmart? And if I don't go press. co2, will the algae overgrow?

you can buy bulbs at petsmart. i would go with bulbs that have a 6,700K rating. no you prob wont get a crazy algae growth as long as y ou keep your ferts in check. but co2 will help to prevent it to begin with.

You should probably look into 10,000 k bulbs if you are not liking the yellow feel. 6700 k is very yellowish:idea: if you ask me.

Stick with 6500-6700K, 10000K has it's own problems. Try daylight bulbs from your local home improvement or lighting center. They are generally cheaper than "aquarium"' bulbs.

Ok, I'll look into a 6500k bulb, and see how it looks

What problems?

 

[Paintballer99]

What if I did one 10000 k bulb and one of the bulbs I have now?

 

[timwag2001]

how old are your bulbs? after 1 year they should be tossed anyway

 

[Paintballer99]

One is about a year old. The other one is maybe, 3 months old.
