Eddie,
With a few exceptions (loud discussions about that here over the years so anyone in the UK who does use chlorine bleach just ignore this post) European washers (again, those who *know* otherwise just, please, ignore this, let's not do that one again) aren't designed for regular chlorine use.
The bleach in oxygen Megapearls is just as effective and far less wearing on the clothes and their dyes.
So, no, you needn't use chlorine bleach nor should you.
I am out of Germany so can't list the various flavors of German Persil accurately right now, so look at this URL to see the current offerings. The Stiftung Warrentest ratings for from 1.0 (best) on down and this independent consumer testing agency ranks German Persil up with the very best, always, if not always the very best (Gold is at the moment, which is why I sent it to Jim).
I have never used a bad German Persil detergent, ever.
Now, here's the deal: If anyone is interested, write to me at my email address for this site and, when I am back in Germany, I will be happy to let you know what's available and what it would cost to buy and send to you. As German postage/freight rates are based on mass not volume (within limits), a compact detergent would cost considerably less than a classic to ship. I will be back in Germany for the new semester the middle of March. Remember, tho', dosage for TLs is going to make this a very very very extremely totally ridiculously expensive proposition, so I'd only use it in a FL regularly and a TL for the fun of it. Persil and Thumpers (Pank! or other flavor) work brilliantly, no surprise...
