The fillter should be ok for that size tank. If you're trying to hide a heater in the filter you'll need to go up at least one more size to the ac70. I'm not even sure its a good idea anyway. The aquaclear filters are made of a brittle plastic and I suspect that the constant hot cycles might be bad for the plastic. It might also be bad for your bacteria if the whole box gets heated up too much.
I was looking at the Finnex heaters but concerned with some of the Amazon reviews. I've seen a few comments about failures after 4-6 months. Any other heaters out there that would fit nicely in the AC70 or should I just try my luck with the Finnex?

I have 4 of them all over a year old(50, 2-250s, 300w), no problems yet. I had the 300W outside from April to October in my Whiskey Barrel pond. All mine have the analog dial, which I believe is the old style that people are posting those complaints about. I don't have personal experience with the digital yet.
