Hello
I have some “mineralized” potting soil.
I was thinking about starting an emersed planted tank using that soil with Schultz Aquatic soil as a cap.
In the past I have tried using the mineralized soils with Tahitian moon sand as a cap and wound up with a lot of Hydrogen Sulfide bubbles coming from the substrate.
I’m thinking that the TMS was too compacted to allow the gas to escape.
I wound up throwing it all out.
I would only fill the water to about an inch above the plants and let them grow to emersed.
Does anyone think that will work?
If I do get Hydrogen Sulfide bubbles can I just use a probe to release the gas?
And will it eventually go away?

Thank you
Charles

Thanks for the reply, this is all new to me.
If your soil is above the water line, then how do the plants stay damp until they
grow to the emergent state?
Do you just keep it covered to maintain the humidity?

If you are seeing hydrogen sulfide bubbles (can you smell rotten eggs) then the soil is not mineralized. If you are keeping the water line below the surface of the potting soil, you don't know if you are making hydrogen sulfide unless you are digging down into the substrate to check.

I just started an emersed trial.. I did not say that Hydrogen Sulfide was coming out of the substrate.
When I did try it, it was a planted 24 gallon aquarium with water well over the substrate.
The soil IS mineralized, it feels like sand.

I'm going with your method.
Do you add ferts to the water?
Also, I was thinking about adding DIY CO2
to the water. But I'm not sure the CO2 would be able to get to the plants after the water is soaked into the soil.
BAD IDEA?
