Welcome to TFF. This is a wonderful forum that is very welcoming!
If you have any issues at all please post them in the appropriate topic section and we will do everything possible to help. Generally, this is a very welcoming forum and everyone is always full of advice and ideas!! If there is a specific problem it is worth posting the water stats (pH, temp, nitrite, nitrate, amonia), what is in the tank in general and as much detail as possible!
And remember ......... there is no such thing as a stupid question!
