Thanks Randy!

Thanks @Randy Holmes-Farley for doing a great chemistry live yesterday! I enjoy the science side of the hobby, this was right that alley! Easy to follow with your diagrams. hope to catch you on future chemistry talks live with randy

I was curious to learn more about this:

Instead of wondering and asking you what trace elements can be combined over and over. Is there a good test we can do to know if 2 DIY traces can be put together? I.E. mixing 2 DIY minor traces in a beaker and if you see precipitation you know its a no go?

Will this be posted as a video - there is a lot of people that was sleeping during the live performance.

Seeing Randy was like spotting a peppermint angel at 300 feet. Rare opportunity to hear from one of the S tier people in reefkeeping.

Thanks!

Mixing and not seeing a precipitate is a decent thing to try. Not perfect, but if you do see a precipitate, it’s a no go.

The reason it’s not perfect is that trace elements such as iron can shuffle electrons between them. Changing, say, ferrous Fe++ iron to ferric Fe+++ iron that may be much less soluble when it hits tank water.

But’s it’s a good step!

Thanks again!! Ill go back to my chemistry lab days in college mixing random solutions hope they don’t blow up lol :) :) :)

@Randy Holmes-Farley thanks for the second great live session! Keep em coming, so much to learn!
I was still curious about these that I did not make it to the live stream chat

Besides nutrients.. what other elements could be beneficial to have elevated, what limits them being elevated in nature?

Are there any new discoveries on your writeup that posed the question “is it better to keep PH stable or alkalinity stable”?

Thanks folks. Here's a recording of it for those who missed it.:

I don't know what else besides alk and pH might be best raised above natural levels, but many folks keep some trace elements higher (e.g., iron).

On the stability question, I think there is a lot rolled into stability.

There seems to not be good evidence that alk stability is the huge benefit folks suggest IF the alternative is the same alk range every day. FOlks dosing once a day see good results, and claiming it is better if the alk flatlines 24/7 is not supported by any clear experiments. For example, 8.5 dKH day and 7.8 dKH night vs 8.2 dKH fixed 24/7.

As to pH, the daytime pH high may matter more than the nightly low (within reason) and a daily ph range with the same daily high as fixed ph may be just as good (or close to it).

We touched on that a bit in the live stream. .

Thanks!! Ive heard manganese at 19 did well in a research project. Looking forward for the next live.
