No. They were kidding.
Do not add bleach to your system. It will kill your tank rather quickly.

I shudder to think
Wow I sure hope no one added bleach to thier systems.

Water travels the path of least resistance, be more then water.
Not dosing...
I also do not dose anything. I recently (almost a year now) acquired a skimmer with the new set up. Before that, only water changes. I think that when a lot of people dose, they believe it will produce a better outcome or short cut to what they wish to have on the advise given by someone or something and not researching it themselves. I have seen people recommend different creatures and chemicals for algae only to worsen the problem because the cause was not looked for/found. Most of the problems were not created overnight, so why should one believe that a chemical/inhabitant will cure it overnight? Granted, my tank is not on the larger side, as most seem to have here, but I think the same rules still apply.
