Default Rock Dust or other alt additives.

Has anyone ever added rock dust to their substrate mixes or as a later supplement? Has anyone ever used any other unusual things in their substrates? What were your experiences and conclusions?

Why do you want to add rock dust?

Potentially longterm nutrient supply, boost beneficial bacterial and mycorrhizal fungi life, etc.

I would be inclined to agree but do you have any specific reasoning? Have you down this? Have you noticed any results compared to ones you haven't?

If you’re interested in the weird and the wacky may be worth checking out clay based substrates

Clay based? Very interesting.

I've used it. It's calcium and any calcium you can put into your substrate is good -common knowledge among frog breeders.

No, I've not put it thru any clinical trials.

This is what I used I purchased it pre made as I didn’t want to go through the steps myself but it is growing plants like crazy and every leaf and rock has springs and isopods on it so it seems to be a big success. Just can’t move it around after moistening it.

I don't see why adding a little rock dust, or worm castings, or other organic sources of fertilizer in small amounts would be a bad thing. I'm certainly not a frog expert but I can't imagine it being harmful to them - and with a decent layer of leaf litter, they wouldn't be coming into contact with it much anyway.

The one issue you might run into is plants growing too well. More available nutrients means good growth, but any plant in the tank that's prone to growing rampant (and lots of beloved plants in both vivaria and aquaria are considered 'noxious weeds' elsewhere) might take over. It just means more work for you to keep stuff pruned.

When you refer to rock dust, I think the fine particulate at the bottom of a bag of gravel. Is that what you’re talking about?

If so, there’s not much in the way of plant nutrients there.

This is a small view of what’s normally in soil.


Aside from Ca ions, there’s not much there that’s present in rock dust. If the Ca2+ is what you’re after, sure, add the limestone or dolomite. Just remember that in adding particulate, that will degrade rapidly with frequent use of ro H2O. Think limestone caves.

I don’t think it matters one way or the other. I wouldn’t go out of my way to add that though. Especially if you’re not growing calceophilic Begonias or something.

Increasing the fertility of your substrate is generally not a problem. Pushing plant growth is generally not a problem. If your tank is set up properly, with good drainage, good light, and proper, passive ventilation, your problem will be exactly the opposite. Your plants will grow like crazy, and you'll be in there cutting things back every month or so.

Personally, I would be very careful about what you may choose to add with the organic fertilizers you mentioned. Your frogs have never been exposed to whatever pathogens might be in your non-rainforest collected worm castings, bat guano, seabird guano, etc.

If you think rock dust is a good idea, for the minerals, please, look into clay substrates. They keep your tank bottom nutrient poor, the way that rainforest clay floors are, while supplying minerals. I believe you will find it more effective than rock dust. (He's not crazy, though, guys. Rock dust is often added to the vegetable gardens of old school, and organic, backyard gardeners. A similar gardening product would be Greensand, also used to boost mineral content of your soil.)
The first clay substrates in the hobby were done by Matt Mirabello. He actually pulled multiple samples from rainforest floors and had them analyzed in a lab for content. Calcium bearing clay substrates evolved from that. That is actually where the hobby got a starting point for how much calcium to add to your clay recipe.
Thanks again for your work, Matt!

A lot of great minds went into the research and experimentation with clay substrates. All I did was condense the good stuff into an easy to follow guide. Here is where all the original groundwork was done. You will see that countless individuals put their 2 cents in, all to build a very informative thread. https://www.dendroboard.com/forum/ge...te-thread.html
