you have 2 10 watt 50/50's.... if that what i am understanding u to say then you need more light. You need about 4-7 watts per gallon to really have a good coral system... you only have 2 watts... you may be able to pull off mushrooms and some of the hardier polyps but nothing hard. Maybe im misunderstanding you though. AS far as waiting to add coral...i would throw at least one small fish in there to make for real sure its cycled, are u planning on doing fish and corals or corals only? If its cycled you can put a coral in when u want... just get something cheap like
yellow star polyps or something cheap in ur area to start off with... and ask the person at ur pet store exactly what kind of care it needs... Also that paint brush thing is called a "
feather duster" look this up on any saltwater website. they are fine filter feeders and depending on what all u have in there may or may not make it. these are EXtrememly common on new live rock... if u wana try to keep it alive and have corals and things of that nature it will be good of u to look into products such as Kent Phytoplex, and their other items for fine filter feeders such as polyps, But for now i would probably just leave it be and just see if it makes it.
