I have been using Grape Caulerpa in my refugium with very good success, however, I have read that chaeto is much better. I just recently got access to some chaeto. My question is should I now use both or should I give all my grape caulerpa back to my lfs? Also, I currently have my refugium lights on 24/7. I do this because I read that the grape caulerpa can 'go sexual' and emit a lot of nutrients into the aquarium, obviously not desirable. If I go with both, should I keep my lights at 24/7? Will this hurt the chaeto? :?

Thanks in advance for any advice here.

Keeping the lights on 24/7 won't hurt anything, and generally will keep caul. from going sexual. Chaeto is all around easier to deal with tho'.
 
Thanks. I think I will slowly remove the caulerpa and go to 100% chaeto. I don't have that much chaeto to start with and I don't want to get a nitrate spike. Does it hurt chaeto to have the lights on 24/7?

With Chaeto, I would keep your lights on the reverse time of your main display lights. My main lights go on from 12pm-9pm, and my fuge light from 10pm to 10 am. :wink:
