So your saying to stay away from a cannister filter alltogether then?
You can (as stated above) 'use the external to house Live Rubble rock, antiphos, Nitrate remover etc.' - I have done this in the past with good results
If i have loads of live rock and a couple of power heads along with a set of 4 t5s (two actinic, two
??), a skimmer and that should do it?
Pretty much yes, get the biggest skimmer you can afford also try to get one that is rated to 3 or 4 times you tank - dont try to save a $ on skimmer they are very important
i like the look of the galaxea, zooanthids and maybe a mushroom, i've also seen a "Fungia repanda" in my LFS would all these have enough light under t5s?
Galaxea's are LPS Corals that prefer higher light levels & are not really for newbies, Zoo's are one I have had some good results with but intermitent failures, I have sometimes been stumped on what to do for the best with Zoa's, currently I have mine under 250w MH lights & they are doing well, water changed every 10 days, Muchrooms will do fine under most lights
I have been thinking about what to stock the aquarium with would a clean-up crew of 2 blue legged hermits, 3 scarlet hermits, a cleaner shrimp, a starfish of some desciption, and various snails be suitable for me.
Cleaner crew looks fine but maybe hang off on getting the starfish just for the moment as they do not do well in very new tanks, they also require long acclimitizations
Fish i'm thinkin of 2 x clown (not sure which species to go for) a goby (again not sure which 1), a cleaner wrasse, and a firefish (u get the idea)! Would this be an ok stocking level obviously to be reached over a period of time.
Look ok just take your time in stocking
I'm also thinking of getting an urchin do they have any specific requirements?
I hate Urchins they bulldoze everything in the tank, they will knock over your corals as well
I think i might put a few tube worms in there aswell?
Have never had any problems with either featherdusters
Anemones do you think there is one that i could keep in my aquarium that might house the clowns, i know they require lots of light, would the t5s be ok?
NO - a 30g is not a good sized tank s for an anemone, they require intense lighting, near perfect tank conditions & have a healthy dislike for filters (meaning they get torn to peices by them)
