Help, please! I bought my first ever new tank last night, for my 3 kids. How close to the top should I fill the water? It is a 20 gallon tank with a Penguin 125 Bio Wheel filter. The water either sounds noisier than I expect when it falls into the tank (plop... plop) or it splashes the back of the lighting fixture. I am afraid to have it too full or too empty.
Thanks for the help for this newbie!
