Crazily it will also depend on which gallons you are talking about, US or UK for example as 300g in both means two different sized tanks.
Would a 300g for life be enough?
Are there any good brands for big tanks that you recommend?
fishtanksdirect is one supplier
I’m also looking at this website for a 300g tank, anyone have experience with them? How did it go?I looked at that one previously. Not too badly priced. Thanks!
