I bought cables when I first got into plants very heavily after Dupla
came out.
Many folks did and this trend sort of stuck with the hobby.
But later as you get better at figuring out what works and what does
not, then you know what you really need and don't.

But I was no different than most new folks about all this.
You just want things to succeed is all and want to get it right from
the start.
That can be done, see James' winning tank AGA last year, that guy had
8 months in the hobby.
