So there's someone in the thread giving advice about a fish they don't even have experience with?
Is there a single filter powerful for the job or are tanks like this always multi filter jobs? Are those 406s as quiet as a lot of the reviews have stated?
3 RBP's for a 70 is the max, 100%. He's correct whether or not he has experience with them or not, so telling someone to stop giving correct advice is silly.
You put any more than 3 in that tank and you are asking for a situation as pictured above.
He's more or less correct, considering 3 is the max RBP anyone should put in a 70, he doesn't have to have kept them to understand stocking a tank. its literally teetering on the line between fine and overstocked. The filtration game OP will play on a 70 with three messy P's is going to be astounding anyhow.
There are advantages of having multiple filters. Such as more flow, a back up if one has a problem, more filtration, also when you clean one the beneficial bacteria can remain unmolested in the other if you alternate cleaning cycles. If you are trying to save some coin, I would go with a Ehiem 2217 and an Aquaclear 110. I'm not saying two 406's would be bad.
Red bellies grow an inch a month for about the first 6 months. They are very messy and having a lot of mechanical and biological filtration is a good thing.
Assuming you are new to this, just keep in mind that 3 RB in a 70 they will be rather shy and timid and my hide when they see you. Thats why said earlier they look awesome in greater numbers in a a very large aquarium, they become less shy in a large group. I have kept three Caribe in a 75 and it was not ideal and IMO was a bit small. Granted they aren't Natteri, but they are pretty close, as close as you will get in the piranha family, a bit more aggressive and a bit less shy.
Ask yourself why you want to keep piranha. Most people get them for the wrong reasons and became rather bored with them, because they do not meet the perceived expectations.

Quiet? Extremely, practically a whisper and virtually silent when kept inside a cabinet.
I run dual canisters because of the additional volume of filtration media, but yes you can get an FX6 and that would work, but it's h u g e.
Getting 2 filters won't be a problem. I'm new to piranha but not completely new to aquariums. I had 2 saltwater tanks a few years ago but had to get rid of them when I went to college. I also know red bellies aren't the vicious predators people like to think about when they hear piranha.
