Thanks all!
And, maybe oneday I will add some live rock. Don't know. Right now, I was after a particular look that I had in mind when I decided to go for s/w. I just added 3 more pieces of coral (dead skeletons) tonight for the fish to have fun with and also, to help with the buffering. (Must complain: Damn those pieces are expensive!
)
Mfish: Yes, it's the former ray tank. And, yes I'm running the U.V. I kept it off the first 10 days waiting to see if I was going to have any spikes. But, none registered (and still none: well, except for the nitrates which are steadily rising; God I miss my constant water changer system). I figured keeping it off would help any freefloating bacteria colonize (if necessary). But, it looks like the bacteria on the bioballs are easily handling the job.
I've searched regarding U.V.s and s/w set-ups and I've read that they are not recommended for corals (and possibly lr) since they need bacteria (besides the nitros.. ). But, since it's a fo tank, I thought it would be fine. (Plus, a little extra protection against ick, etc. and, as always, the bonus of crystal clear water).
BUT, please let me know what you're thinking. Any problems with the U.V. and my set-up?
I'm still immensely in the learning phase here and will listen to all informative replies...
Thanks for the compliments and also, thanks again to all that helped me out along the way.
Richard.
