Hello! "NEWB" with some Q's

[magikof7]

ok I bought the tank for 150. It is about a year old and wow it needs cleaning.
Very nice couple. I told them about canreef and RC hopefully they join the forum. They are relying on 1 store for all their info.
They had a beautiful little clown ( a yellow banded she called it) he was hosting a very bleached anemone. Several tangs, a couple of wrasses, blennies and, very full of live rock not sure of the size of tank but it wasn't big enough.

So What do I do now!? (lol) going to go get a couple of bottles of vinegar I think.

Might get hubby to build me a stand the one they gave me is just a table from Rona.
They also gave me a jager 100 watt heater and I think a koralia powerhead but Im not sure of the size. I'll get pics up maybe someone can tell me and if I need another to go with it.
