my rice experiment

And one more. A 100 gramm of rice contain a 100 mg of P. Perhaps it balanse with N as 1:10. So we will have a 1000 mg of N or 3000 mg as NO3. In 100L tank we will have a 30 ppm trates from 100g of rice. That is completely out of concern.

Yes, but what might be getting trapped in or on the grains might be of concern, as well. Some folks are having some stuff growing on the grains that might be adding to the problem, as well as organics which maybe adhering to the surface of each grain.

I don't think that can be significant influence in work of "rice machine". Also we may simply replace all of bad rice with good rice at one time.

That's true, but how many people are actually doing that? I bet none, seeing as how everyone wants to know what the breakout point for this is going to be. I think folks need to start testing for other things besides the stuff that they're looking for. You know, covering all the bases. If you don't see problems coming, then you can't take evasive when the time comes. So bad things don't ambush you.

DJ, i don't understand one thing. How the rice reactor can act as "nitrate factory". That is out of my imagination.
 
I've tested with different kits by the same company. I hate to keep saying this, but I have very little spare money these days till business picks up. So I can't just order new kits. Therefore I'm limited to what I can buy locally. Which is only api...and even that is hard to find. No one carries an NO3 kit in this town...so I'm stuck with the two I have from api, an old and a new. I mainly test with the new one, but when I do test with the old it has the same results.

I don't know about a factory but the rice adds fixed nitrogen just like fish food via proteins, vitamins and vegetable matter as well as fat and carbohaydrates. At some point in the nitrifiction/denitrifiction processes that nitrogen that isn't consumed by animals ,bacteria and algae and converted to tissue mass should go to ammonia/nitirte and nitrate.It is an organic carbon source but not a very pure one, imo.
 
that is something I hope to monitor now after adding more rice. I'm wondering if my nitrates will now go UP. If they do I will probaby end the experiment completely.
 
Having spent the last 2 evenings reading the 24 pages of this thread, it sounds like IMO two things are at play here; either the rice one person is using has a slightly different make up and therefore different effects or it could be that the difference or lack of bacteria between each persons tank could be inhibiting denitrification in some cases (bacterial imbalance).

It sounds like the rice might be breaking down and releasing nitrogen etc but not being broken down by bacteria or the right bacteria. I would try reducing the amount of rice and dosing a bacterial product like mb7, zeobak or waterlife bacterlife.
 
greetings to all

As he had commented on i-reef forum, the NO3 were not the problem at the end of this "week" there were several changes as shown in the chart below:

color change in the granules of rice not perform at all:

in the following images, the question arises whether they are grain wrap or nitrate floc ?:

shake vigorously to the reactor and remove the shell or floc in full and after two days, the NO3 decreased to almost undetectable.

Forgot to say, this looks very interesting. I'm the guy mentioned earlier who tried to make my own bioplastic and it wasn't massively successful due to it breaking down/disintergrating unpredictably and causing occasional blooms. Looking for a stable carbon source and short of using barley straw like they do in ponds, rice could be a winner...

This is an awesome thread and would like to say keep the tests coming :)
 
@coltrref sounds like the rice that he used could have had a thick coat of (nitrate based) preservative or alike??

p.s. thats quite a rise and drop in NO3 in one week.
 
Hi Cliff,

He could try it, but after the last post by coltrref it sounds like the problem isn't a lack of bacteria :)
 
I agree regarding coltrref's problem. Apparently the rice needs to be soaked well before you put them in the reactor. I'm not sure if coltref simply rinsed them or soaked them well perhaps several times before use over a period of several days? From the pictures seen when the rice was soaked overnight, there was a lot of stuff in the water. I would not want to add all this stuff and would want to triple soak it out to the point where you would not have any whitish color in the rodi water after soaking. It was not made clear to me, if you can get clear water after soaking the rice. :)

If the rice continues to dissolve in rodi water without bacterial action, I don't know if this is good then. :(

with respect to PO4 I did all the doubts, and had commented that the power for the NF's which is daily, the PO4 in my system is a daily battle.
with the help of the Chaetomorpha and lanthanum chloride have been controlled in low ranges.
but to implement the train of rice, failed the lanthanum and this was his behavior:

can observe the increase to 0.1 mg / l, so I reboot again the addition of lanthanum to decrease.

one of the characteristics of rice in my country in its content and even of some brands is up 6% in phosphorus, iron and 7% respectively, large developers to algae.

maybe philbo32

I agree regarding coltrref's problem. Apparantly the rice needs to be soaked well before you put them in the reactor. I'm not sure if coltref simply rinsed them or soaked them well perhaps several times before use?

vigorously for several minutes, rinse and soak the rice for a few hours.
