Addon:
Even though it's getting a little tense here, I would be happy if you stayed and continued sharing your knowledge, but, of course, do as you will. As I said before, this thread does not only serve but others to brought by Google, so I will continue adding input here should it be worth it.

I mentioned several posts above that I was onto the Dutch Pro crowd, but I didn't elaborate on it as I hadn't found anything worth mentioning, but now I do. The guy asked did I have Multi Total, and I actually did, as it came with my starter pack — I didn't find it really useful, or so I thought. He told me to add that in and leave it settle for 24 hours and let him know. So indeed I put the last of what was left of it, because it came only as a small bottle in the Starter Pack, and listen to this. Prior adding it, yesterday, the Res's were cloudy and the stink was getting more pungent, and also more sudsy stuff appearing. Today no stink at all, whatsoever, nothing! The res is still cloudy as before, but no stink, and all the suds is gone too, maybe just tiny bit left. My pH hasn't budged since yesterday.
Just thought it'd be worth to mention.
