BTW, I usually buy "one size up" when buying ACs. In other words, if I have a 45g tank and the filter is rated for up to 50g (an AC
50), I'll buy the AC
70 instead. Basically what you've discovered. Extra filtration capacity never hurts.
(As an alternative, you could have put two AC
50s on that tank. Either works well.)
