Lighting Question - t5's

[JonnyJ]

i have the 20" nova extreme pro on my solana and i need to buy new bulbs. they have dulled out the past week very bad.

its a 6x 18watt bulb fixture.. stock it comes with 3 10k and 3 actinic.

im definitely looking for more of a blue look but dont want to change anything if it will affect growth....

would 4 actinic and 2 10k be a difference for growth? how does it work?

i want to order the bulbs today through russ at salt water critters.

thanks guys.

3x3 (3 actinics x 3 10K's) is pretty good ... but if you want more blue add the 4th actinic.

What type of corals are you trying to grow? Softies, LPS, SPS?

 

[JonnyJ]

softies and lps, no sps

Go with the extra actinic ... simple.
