update day 7

ok it has now been ONE week running the rice on my system

here is my observation so far

1.algae just seems to immediately die away within a few days. I guess the rice is pulling out the nutrients FASTER than the algae can take them up.
if your going the rice route, watch out for your macro algae, your not going to be too happy with ur macros reaction.
infact I gave my chaetos to a fellow reefer just to save it from dieing.

2.if you have gha or any other kind of algae, this is definitely the way to go, but remember you will have to do a lot of cleaning, like I'm doing now, and this will result in a longer hazy water period.

3.my water is still not 100% clear, its still got that look when you dose purple up. but I'm fine with this becasue I know that I'm pulling out a lot of algae, and i still have not started on the rocks yet. I will be doing a 30% water change in the next few days, and will use this to clean my rocks as well as re-aquascape my tank.

4.the only guys that I really noticed effeted by the rice was my tiny feater dusters. there were practically 40-50 on a rock but that reduced to like 30ish. but I think this is because they got suffocated with algae dieing on them (since i wasnt cleaning the first few days). to elaborate, the dieing algae was covering the little feater dustes and must have killed them. there still are a lot of them on the other side of the rock. so I dont think rice was the problem.

5.skimmer is still pulling out a lot of gunk. this is what my skimmer looked like today, just one day after cleaning it. yes I cleaned it yesterday.

still skimming like a champ.

6.i will be posting up silicate test on the rice later tomorrow.

7.heres a shot of the corner of my tank. this is two days ago.

I didnt take a pic yesterday.
and this is how it looks like today

8.as far as the actual rice is concerned. it seems to be holding up pretty well. you can still see each rice is individually tumbling over and is not stuck together or has not become mush or mulm like the bio-pellets. the rice has got a tint of yellowish color to it now, but that just might be the bacteria covering up the rice. I guess approx 200gph should be enough to tumble the rice in a reactor.

9.all fish are happy as can be and are not showing any signs of stress.
corals are back to normal and are showing normal PE.
infact my bubble coral is starting to show more PE. my bali green slimer which was starting to lose color and turn brown is now holding its color, and I guess it will start to color up soon.

10.I am currently feeding my frozen food without washing it so that I get some more phosphate into the system, I'm dosing extra coral food as well. and this could also explain my water hazyness.

11.my glass is cleeaaannn, the places where I've cleaned is still clean without algae growing. the places where I left the algae growing has now slowly started to clear up.

I hope my and icycorals updates might have gotten others interested in starting their own rice reactors, let me know if u guys need some help.
 
My two reactors are connected in series, so carbon first or rice first?

As rice is cheap, so can I replace it more often, say every two or three weeks? Or must the rice need time in the reactor to have the chemical effect?
 
If I was setting mine up yet (My salt showed up today... so soon..) I would run carbon first as no one is entirely clear what rice is doing yet other than it seems to be working well in a couple experiments. Rice seems to hit hard and fast from what I've seen so far, so start with a small amount.

I think I may try with actually running it in a bag in one of my skimmers. See what happens.

carbon first then rice, you dont want the bacteria colonizing the carbon pellets or blocking up the carbon reactor.

so carbon in first reactor, rice in second. but the rice SHOULD have a slight tumble. and the outlet from the rice should be near the skimmer

are you going to try it on the 750g in ur sig?
I really dont know how much rice you need, but I run 1 and 1/2 cups on roughly 100g, and icycoral runs about 1/2 cup on 60g. I think I have a little too much and he has it on the lower end. so I think about 1 cup for every 75gallons or so should be good as a starting point. but in your case I woul just go with 3 cups or so to start of with and slowly increase. ur way up to 1 cup for every 75g.
 
quick update

just did a no3 test with my salifert kit
and look at this

no3 is so low that I cant even detect it with the low range test. I used to get nitrates of 2 to 5 even with my gha and all, but with the rice, its undetectable. just like how the phosphates were on the elos kit.

maybe I need to cut back on my rice a little bit?
or let it run for another week and remove all algae and clean rocks and then wait to see the result?
 
this is really interesting stuff i can't wait to see what happens.

How long do you think until the rice gets all mushy and gross?

Wow that's pretty awesome man. I'm going to order some test kits this week to get some real numbers to post. Should have picked them up before starting this but oh well.

Quick update

Did the family thing today so I didn't get to Check all my params but everything is looking great. All corals look fine getting good polyp extension and colors. My lps seem ok scolly, blasto, and and chalices looking good. zoas and softies look like they are adjusting to the changes in water chemistry well also. My orp is reading 337mV I thought that maybe the probe was dirty so I checked it with redox test solution and it's reading good. I almost fell over when I saw that my orp went up 44mV in 24 hours. Only been cleaning my glass every other day now. And I forgot to mention that yesterday I started removing my cheato going to remove one handful a day and see how it goes. So far so good will let y'all know if it goes otherwise. Oh and the rice still seems to be holding up after being tossed around in salt water for a week.

It has been at least a week and the rice still not close of getting mushy.

I think it have to do with the temp.

Its been a little over a week, and the rice is still holding strong. I think its because the temps are not too high thats why its still not become mushy.
overall I think it should be fine for atleast a month or 2, as long as the tumbling is not too vigorous or anything like that.

everything seems so good about rice, its almost like its too good to be true.
infact, it even adds a little calcium and magnesium and other required trace minerals.

it just might be the next big thing after live rock as far as filteration is concerned (bio-pellets aside).

its a good thing that u are measuring the orp since I dont have an orp monitor.
I think I need to do a little water change and remove a bit of rice.

if more people are willing to try the rice, we can even figure out how much rice is required for each system.
 
haha, didnt even think of thread of the month
what would be really cool is if people started using rice as their main biological filteration system, and if this rice thingy really kicks off, WOW
 
From reading the thread it seems to be doing more harm than good...

WHAT??
how can you say that?
results have been positive, there have been NO cause of concern and there was NO harm done whatsoever.

so how can u say that its done harm?
u're the first person to say such a thing, so when u say somehting like that, care to back it up?
we have backed up our results with pics
