It is sounds ok, for beginig.
But can you explain the principe of pellets dosage? Why 1L per 500L?

Yes, but they did not give any reasonable explanations of this.

Noted.
It was only referenced so rice users can approximate the dosage of rice in their reactors, ie. about 10% of the dosage of similar commercial pellet products.
Seems going back and forth on this heavy metal thing rice user or aware of this problem.
But what worry me is that vendor has the money and the know how to make rice a market produce for reef use. Plastic pellets is a good prouct but it not working for all reefers.
Rice can be process to be reef safe it just matter of time you not the only one playing close attention to this.

lol, I didnt realize that I came off that way.......my apologies to acrotrdco and anyone else that thought I came off that.
as for acrotrdco giving the numbers, I've provided the numbers myself. AND I AGREE that we need some set standard to compare it to, and hopefully randy will come on here and sort this out either right or wrong.
until then, the numbers in rice are not really too much to be worried about and I can say this since I HAVE it in my tank and there are no ill effects.
infact I think my tank must be going thru a mini-cycle after all the die off etc, but the rice has curbed this and I dont see any stress on any of my corals, other than the regular lil stress from 24hrs of almost no power.
I will be taking pics and stuff tomorrow so that I can post it.
just imagine all the money the bio pellets guys get from their products. rice is practically free to all of us and this will definitely take a big chunk of their profits.
as for heavy metals, put ur output into the skimmer or carbon reactor and then you have ZERO worries.
Update
1. 1/4 to 1/2 cups per 50 to 75 per gallons
2. soak rice at least 24 hours after that rinse rice at least twice.
3. How long will rice last. So far month but stills pending.
4. White rice long or short grain will work fine.
5. You can use reactor or place it in the sump.
6. Beware of your skimmer it go wild my need to adjusted.
7. Do to heavy metal concern maybe active carbon, poly filter, etc may needed to added it not use already.
8. Vinegar dosing can use boost up bacteria also can help come down the smell from the skimmer and improve waste exportation.

This something they will try not let it happen. :fun2:

Of course not. In one month after people pick up on rice you will see biopellets in new packaging with bright red letters:
THIS PRODUCT IS FREE FROM HEAVY METALS THAT WILL KILL YOUR REEF!
I think this will be the new marketing campaign of biopellets. Even if in the end it gets proven that the concentration of heavy metals is minimum and nothing to worry about!
good list elijaher.
will definitely compile one when I have a bit of time and stable electricity....lol

You do have to understand that in our hobby, people have thousands or tens of thousands dollars worth of livestock in their tanks, it is just normal for folks to be cautious. We always hope for the best but prep for the worst.
If rice indeed works that'd be great, but simply ignoring potential risks when doing DIY projects like these is just unwise. If like you said the minerals are skimmed away that'd be great, but what if not?
Also you should realize beside rice there are also other DIY or alternative biopellets that's also very affordable but without the potential risk of minerals accumulating in the water.
Anyway if folks really want to start building their own rice reactor, please, start slow with smaller dosage then gradually add more.
this is something I wanted to check as well, and looking at my rice, and my levels, I think it decomposes only when it needs to.
when I started this experiment, I didnt notice any degradation of the rice.
but now that my system had a power failure and stuff, I've noticed that the rice has indeed depleted a bit, but I need to check if the rice has come out of the reactor and into the sump or if the granule size has actually reduced.
I run a quiet one 5000 for my return pump and it also powers my rice reactor, when I restarted the pump after the power outtage, there was TOO MUCH flow in the reactor and I think the rice seeped out of the reactor. I will get back to you exactly on this within a few days once I stablize everything.

For concerns about heavy metals (copper), I would run CupriSorb resins. The problem with polyfiters is they will only remove copper ions down to about 30-40 ppb which is still quite high. GAC is necessary to remove the heavy metals tied to organics, which is the form most of the heavy metals may end up as and are thought to be less toxic in this form.
FWIW, most tanks seem to run in the 10-30 ppb copper range as is, which is still quite high IMHO. I think running CupriSorb resins makes sense to run in all tanks as well as GAC. Copper runs about 0.9 ppb in unpolluted reef ecosystems.

dave, i think because ur using it in a bag ur not seeing as quick results as wel did. I suggest u put the bag in a high flow area.
as with gfo and carbon if u put it in a bag in the sump water flows AROUND it and not thru it, this is the same case with the rice and you will not see as quick results since ur rice is not exposed to the flow.
u would definitely got a bloom if yours was in a high flow area.
The master has spoken.
so my 0.9 number WAS RIGHT.
highlandreefer could you please look into the rice numbers and do the math since you are more chem swavy?
that would be great.
FWIW, I've got a lot of sound advice from highlandreefer in my previous threads, and since he hasn't been too alarmed about the quantities of heavy metals in rice, I dont think we should be either.
highlandreef pming you right now.

The figures presented seem reasonable to me. FWIW, there will be more copper and heavy metals added in a water change using the reef salts we have then what would be added in one normal amount of rice used in a reactor over the course of possibly several months. I would think these heavy metals in rice will not be released all at once too, which means quite a lower dose would be added per day. The same applies with most of the fish foods we use, as far as their heavy metal content, you can get considerably more heavy metals added in just a few feedings. The bacteria will remove a lot of heavy metals as well when consuming the rice, which will further reduce the heavy metals content, plus from studies the starch consumption by bacteria results in reductions of the total heavy metal content & are used to remove heavy metals in waste water. 
Personally I don't see the concern with the heavy metals content of rice used over the coarse of several months, provided that this rice is soaked several time before it is used in an aquarium. I'm not sure exactly what may be applied to rice to meet USDA standards other then the vitamins. Your picture of what rice soaked in RODI water looked very cloudy and I would not want the contents of that cloud in my tank.
One hobbyists in one of the two threads simply rinsed the rice and then used it. The results were quite high nitrates. I don't like this and believe the rice really needs to be soaked well before use to help remove heavy metals and the vitamins added as well as any other impurities on the top layer of the rice. Personally, I would triple soak the rice in rodi water before use.
IIRC, salt mixes contain around 5 -20 ppb of copper when mixed to a salinity of 1.0264.
FWIW, it may be possible that using rice in a reef tank may actually help reduce the heavy metal content.

Good Points Cliff!
Just a question: The White rice - is it not "fortified"? Meaning that in order to meet USDA standards, it is processed in such away to add back to it some vitamins and trace elements/minerals?
Is that be the case - why not run the experiment with a natural, wild rice ?
If rice is like flour - when you compare the white bleached flour- vs - the the organic, stone ground varieties you will see quite a variation in nutritional information between them.
*IF* this parallels what is seen in the labels of wild organic -vs- white rice, it seems that this would/might translate into different performance in our aquaria??
Comments please Cliff?
