CUC suggestions

[DAVE]

Hey Everyone,

I am looking for suggestions for a CUC for my two reef tanks.

I have a 150 and a 220. Both tanks have a 2-3" SSB with a larger grain substrate. Both tanks have been up and running for about 6 weeks now and at about the 3-4 week mark I started to see the diatom bloom. I have been gone for 2 weeks now, so I am sure it will be much worse when I get home from work tomorrow.

Now my question:

What CUC would you put in each of the tanks? How many? Both tanks will be community reef tanks with no real aggressive fish.

Any sponsor here have a decent amount/variety of CUC in stock?

Thanks for the responses,
Dave
