Hi all, been reading on here for a good while, trying to absorb as much as i can before i started setting up my first salt tank. I've had fresh tanks for years and years, allways wanted a salt tank, just never felt like i knew enought to be able to care for one, and thats just not fair to the tank residents. Well just under 2 weeks ago, i was willfully thrust into saltwater tank ownership. The short version is that a buddy of mine had to suddenly move cause of his job, and so he gave me a really sweet deal on his tank. \n \nIts a 75gal(best i can figure by the measurements and by how much water i had to mix up to fill it) flat front curved corner tank, Georgeous by the way, and all the fish and filter and everything that he had, right down to the last few cups of salt he still had.\n \nso, i got it all packed up, moved it the 2 hours to my house, got it all set up, and everyone survived. Inside the tank there was around 25lbs of LR(not nearly enough) about an inch of white sand, a clownfish, a 14 inch snowflake eel, yellow tang, a black and white one, and a gobi i think, he's tie-die'd lookn. (sorry the names escape me at the moment)\n \nanyway, so I'm trying to learn as much as i can as fast as i can, getting the tank before i was comfortable in my knowledge was not my plan, but when a deal this good comes along, you kinda just cant pass it up.\n \nI will say this, my buddy didnt have much in the canister filter, so i got all the stuff and filled it up last night, got some more salt, and some other stuff. I know i made a mistake, but when i set this tank up, i used tap water cause its all i had, and so now i'm replacing all the water with RO water as quickly as i can.\n \nMy wife is beginning to squak about the $$ i'm putting into the tank, and that i spend all my free time with my fishy friends, and not her, so i guess all is normal with the world.. :mrgreen:\n \nMy biggest issue as of right now is all the red/brown sruff thats taking over the tank, but i'm sure that a good portion of that is cause i was an idiot and used tap water..... oh well, no one died, and i'm fixing it as fast as i can...\n \nAnyway, thats pretty much the short version of my story, I have a few pictures, so i'll try and post them....\n \noh, and the last one... is that whats called a feather duster worm? thoes are ok right? When its fully stretched out(the feathery part) its maybe the size of a dime, give or take.
