Wow, sorry to be a bother again.
I am trying to do things right this time around and seeking advice from folks who have more experience than I do.
I am still not sure if I want to go salt water or fresh for the 55g tank. All I have for it is the glass and lid (with no lights).
I am thinking of a sponge filter for it. Seem like cheap and low maintenance. I bought one for a 20g I wanna set up but haven't run it yet. Link to teh one I am looking at is Lustar Hydro-Sponge Filter 4 at Big Al's Online
I am still not sure for the heater. I think 200 watt is the minimum I would need for a 55g tank.
My other 2 tanks are freshwater and i think I might want to get my feet wet with some salt water. I know the initial cost is more. I am digging getting some star fish but at the same time know nothing about a SW
set up. I know if I want coral I will need a chiller (another expense).
I have no idea what live rock is.
So if anyone can point me in the right direction for either set-up. I am looking at semi-cheap priced items and save the money for the fish.
