OK APUG-ers, I realise this is a walk in the park for all you experienced folk but I thought I'd better share my first success given that I've been pestering this forum with my newbie questions over the past few months. All chemical components mixed from scratch, thanks to this Forum or I probably would have given up on mixing my own.

Especially thanks to stefan4u, polyglot, Gerald, Athiril and of course PE for patiently answering questions.

And.....One more question!

Obviously there's a lot of dirt. This seems to be from the bleach which I noticed had a lot of sediment in it when I first mixed it. I guess I will need to strain it. Is there something I might be doing wrong to be getting so much sediment in my bleach?
