I too have a few decades of fishkeeping under my belt and I feel that what was once standard and acceptable was actually subpar. Sure, even under poor conditions fish still grew to adulthood, but it does mean the conditions were optimal or that the fish thrived. Human beings are also able to live long lives under slum conditions and poor nutrition, so why not other creatures.Hello; Having run tanks decades ago with bubblers only and with very weak powered filters, by todays standards anyway, I find it interesting that a filter rated for 110 gallons might not be considered enough for 75 gallons. Tanks can and have been run with no filtration at all.
Are power filters today better than what I had long ago? Of course they are. I use them myself. I have not yet found the necessity to go as powerful as is possible. I suppose decades of running tanks with truly underpowered filtration has given me a different perspective. Even when the early power filters began to be available at prices affordable to me, I often ran tanks with filters rated smaller than the tank.
Consider the sponge filter. I have and figure many of have run tanks on a bubble operated sponge filter.
All this said, if a fishkeeper can afford to buy and pay the operating costs of the very powerful filters they will work just fine. I suppose the only limiting factor as far as some fish go would be too much flow to deal with.

I would never, ever go back to raising fish the way I had in my early years, I believed I've significantly progressed in my understanding of water condition, nutrition, etc. Of course, in another 20yrs, this could all change
I never said that an AC110 isn't enough filtration for a 75, but rather suggests that the filtration could be even better based on the OP's planned stock. Heck, with enough water changes, you actually don't even need any filtration
Even with modern power filters I do not foresee water changes going away.
I guess it depends on how much work you're willing to put in i.e water changes, vaccuum etc.
I think it will be a good idea for me currently to keep a light stock (no oscar no piranha) as im busy with work and college. I am probably gonna go with one green terror or jack dempsey, along with a couple smaller cichlids like green severum
And is green terror a no?
