Freshwater live rocks?

[Nont]

Hello,

I'm wondering whether there is a freshwater equivalent of live rocks. With microbes and endoliths?


Cheers, Non

Hi all,

I'm wondering whether there is a freshwater equivalent of live rocks.

It is probably <"sunken wood and leaf litter">. If you have a substrate that is mature and fairly undisturbed that will also fulfil some of ecological functions <"Aquarium Biofiltration - SWISSTROPICALS">.

If I were to construct a concrete live rock with porous and anaerobic area, do you think it is possible for an interesting microbe like this "iron oxidixing bacteria" to form? Maybe something similar to the substrate in this thread.
Btw, I’m interested in this aquatic microbes stuff in the soil or rocks do you know if there is any books about this topic?

I'm not sure it would offer any advantage over a substrate. Have a look at <"Anoxic denitrification in canister filters?">.

That is perfect.

Possibly, I'll see what I can find.

While not the same thing, I recall some really cool posts from a member that was looking at things differently. You may get some inspiration.

Thanks Darrel, speaking of this topic, I’d like to hear your your opinions on whether the aquarium “legends” are true e.g. Anaerobic pockets are harmful, Nitrifying bacteria doesn’t live in water but only on filter media, substrate and glasses.

I’ve seen his mars simulation project which makes me start this thread. Just seen the one you attached ,and I’ve got cyanobacteria so it would be cool to try this one out!

Not really my field, but <"I'll have a go">.

e.g. Anaerobic pockets are harmful,

I think all substrates will probably develop anaerobic pockets if left undisturbed. If you have plants I think this is a good thing, the zones of fluctuating REDOX values <"Modification of sediment redox potential by three contrasting macrophytes: implications for phosphorus adsorption/desorption">, caused by radial oxygen loss in the root rhizosphere as the root extends into deoxygenated areas of the substrate, will make many nutrients plant available.

Nitrifying bacteria doesn’t live in water but only on filter media, substrate and glasses.

I think that one is nearer the truth, nitrifying microbes occur in biofilms. In something like sewage treatment there maybe no solid surface, but the plenty of <"microbial flocs"> composed of a whole multitude of differing organisms.

The other site for nitrifying organisms is the root surface, even if that is the root of a floating plant in the water column. Traditional views always vastly under-estimate plants <"Limited effect of radial oxygen loss on ammonia oxidizers in Typha angustifolia root hairs - Scientific Reports">. Have a look at <"Amazon Frogbit (Limnobium laevigatum) phytoremediation references">.
