Freshwater live rocks?
- Thread starter Nont
- Start date
Hi all,
cheers Darrel
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?
Hi all,

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!
Hi all,
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">.

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

Hi @Nont
I have been thinking about this. I think live rocks could be promising as a culture starter for infusoria because it can be a bit <hit and miss> sometimes and there is a real demand for live food suitable for small fish fry like nano-tank rasbora species. The main premise for "live" marine rock is to firstly reduce ammonia and it's derrivatives, but also to seed copepods, which provide the second largest source of biological molecules to fish in the marine food web (after krill). I should imagine that it is quite possible to develop a live freshwater aquarium rock that is seeded with copepods, rotifers, nematodes and the like. Why don't you do it. I remember you were thinking about a way to get into the industry. I cannot think of a better product to invent, assuming experiments yield good results. <199470 ha of land> is used for aquaculture farming in Thailand and... "Out of the total area, 61% is used for freshwater farms". That is incredible. We do not even come close to that in the UK. Perhaps visit some of these commercial freshwater aquaculture farms and check it out firsthand.

Part of the appeal of live rock was all the fauna and bacteria that came with it. Some reef keepers who live near the sea dump dead rock in a convenient rock pool for some months before transferring to the tank. There’s no reason why you can’t collect rocks and wood from local rivers, streams, ponds etc..
I did that when I set up my shrimp tank. Took a load of dirt from the local river, some wood and rocks from my pond. The amount of wee beasties that appeared was fascinating. Got newt larvae, dragonfly larvae, worms, snails, leeches. All sorts of cool stuff.
Is that a good thing? Possibly. I have a hands off approach to the shrimp tank and the shrimp are all breeding and the plants are very happy. I could have ended up with anything in there though so it’s all a gamble.

The nearest I got was in a low tech cold water tank with a lump of rock from a canal reservoir which had zebra mussels and sponges growing on it. Not really what you are after.
