I understand, for me I've never seen any precipitation, ever, outside of forgetting to lower ph after silica before calmag. To each their own of course. The reason i don't use all their products is because i believe others are better like the data i posted on silica. I know GH has spent a lot of research on the trio, decades ago, before anything else they've made, it's tried and true, while their supplements have changed recipes more than once over the years. If that makes sense.
Never ever have smelly water, i never have any adverse effects from mixing it up. Only ever seen chelating when mixing out of order or not checking ph before calmag. Never used hyclean, or any cleaning products outside of cleaning prep for the next run.
To each their own, but just want to say that it's not bad to mix products across the board in a blanket statement. At least in my experience.
