Questions - Need some input

Can someone please tell me what the steps are to "seed" dry rock using existing live rock?
Thanks in advance,
Jim

Has anyone had any experience with equipment (lighting, pumps, etc) from Odyssea? Their aquatraders website sure have some low prices... but I did read the post about being cheap!

He went through the Eshhops overflow and perished... should we have provided a cover on the overflow?

Hi All,
This picture includes two critters that we arent sure of. They both hitched in on some LR we bought from a guy breaking down his 220G. The larger one I thought he said was a "leather coral." Is that correct?
The three smaller ones on the same rock moved around the tank for a while then seemed to take root where they are. Actually, there are about 8-10 of these in all in the tank... all in various locations. We even observed one on the glass for a while when they were ...

There seems to be some written, not a lot, but some opinions as to whether to cover the display tank with glass covers or not. I'm quickly gaining a lot of trust in the replies posted here... so what do you think?
Thanks,
Jim
