No worries Mojo
All I can do is call it as I see it and I do try to be as honest as possible. I am more experimental with what I use mostly out of necesity. Some times I freak myself out with what I try so I do try not to miss lead people.
Ken the Mt Sylvia diatomite I have I think is much whiter than maidenwell even when wet. I was thinking the yellow from owies pic was from the yellow background.
Just a thought Ken but are you sure the wet stuff you show is not maidenwell. The bags of mt sylvia you got for me I don't remember it changing colour like that so much? I'm sure mine stayed white as in owies pic. I will have to have a closer look when I get home.

i have been using lavalite as an alternative to richgro aquatic mix because the big B ran out of the richgro aqua mix. As far as i can tell it's pretty much the same stuff just a lot whiter have potted up into a mix made with it with no ill affects so far

the test will be in a years time when repotting to se if it holds together.
Richgro aqua mix was another that changed what it contains. Used to be spongelite (Think Grant Called it that, not sure where he got that as the bag does not state what it is) (Years past Ken and I thought it was Diatomite as it looks very similar) But changed to what now looks like the white diatomite in a smaller bag. Not sure though as I have avioded the smaller bags it now comes in but have been buying up all the old package bags from Bunnings whenever I see them. The old Richgro aqua mix or "spongelite" is one that I think Grant's tests showed has a high pH so may be best used as a part mix with organic material. I have used it once last season as a 100% mix and it showed signs of nutrient issues later in the season. Not sure if a more agressive fertiliser routine would help but found it works great mixed with organics mostly replacing the grit.
We do need to remember that even minerals of the same name can have different properties when mined from different locations. I learnt this years ago when the first zeolite I got hold of was white in colour and more chalk like and less rock like than the red/brown zeolite that we all know. God it was on a wing and a prayer back then before Ray started stocking the zeolite we use today. The guys as Chastlemine zeolite instructed me that the white zeolite was a few million years younger than thiers

The white zeolite seemed to work ok but it has been years since I had a supply of that from the local mine supply store which was an oil soaker agian. And it was not cheap!
It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
