View Full Version : Another lighting question

03-26-2011, 12:25 AM
I have 4 bulb fixture and I have the following bulbs:

2 39w 6700k

2 39w 10,000k

2 39w Actinic bulbs

I have the ability to time the bulbs to run two bulbs at different time or all on at once.

I have been warned that the actinic will cause algae. The fish sure pop with this color bulb.

I was thinking two 6700k on one bank and a 10,000k and actinic on another.

I am worried about the algae.

I would like some recommendations so I have nice balance of light for fish and plants. I would also like recommendations on the amount of time to leave the lights on.
