Well, like they say....if it ain't broke, don't fix it.
If your water is clear and your fish are healthy, just keep doing what you're doing.
I wouldn't shut anything down.
You are doing the right thing by learning what you have there.
That being said, I prefer simplicity. If I can achieve clear water and healthy fish with a system that is simple with little, if not zero maintenance, that's a plus.
I don't do much when it comes to filtration. The bog does it all on it's own. I just sit back and enjoy.
A hobby with constant work is no fun to me.
