Hey guys about 2 weeks ago I moved my 3 little RES from a 25 gallon tank to a 70 gallon tank with a new heater, filter and lights...I have a fluval pump with 2 medium sized air stones and I bought a fluval 306 because thats what the guy suggested at the store but im thinking i should have just gone with the 406 because my water is already looking bad to me, any input is helpful...here is my setup brand new
and here are my 3 little ones Cosmo, Gizmo and Axel

Here is my tank as it sits right now...

Here is a side view, notice the almost redish tint to the water
