What does "rtn problem" mean? I'm not familiar with that acronym.

I dont know if my spelling will be right but rtn stands for rapid tissue nicroses.

What symptom are you trying to remedy with XPort PO4? Are you testing phosphate? What do you suspect is causing your RTN and why?

I'd like to know also. I've run biopellets on 2 tanks for around 1.5 yrs now. Neither tanks are sps tanks though, and I want to start a SPS tank soon. Biopellets have kept my nitrates at 0. If I can't use them for sps, dang..

I am trying to get rid of phosphates with the XPort PO4. Cause the stuff Im using now isnt working.
The cause of the RTN I can not pin point it to just one thing. But after losing power to the tank for a day or 2 in the summer everything just started to happen... I had red slime algea that I couldnt get rid of. New frags would RTN a day or 2 after I put them in. I had colonies for a couple of years and they rtned on me. Everything just started to go wrong. But like a friend told me why mess with it if everything is going good. Cause I wanted to lessen my elec bill by getting rid of a couple of pumps so I got rid of my nitrate reducer and my TLF gfo reactor and went to the bio pellets. Well the pellets held down my nitrates but did nothing for my phosphates. So I had to add the gfo reactor back. And since then I could not get the phospates down to 0 ever.
So what I did was went back to where I was when everything was growing good, I put back my gfo reactor and my nitrate reducer back on and took out the bio pellets. A fresh new start took all my frags and colonies out gave them to friends and started all over again. Only added 20lbs of fine sand put more lr in and now we will see what happens. I put a couple of the frags back and 1 started to rtn on me yesterday when I put it in it perminent spot Im guessing in to much flow cause after I dipped it and fraged it I put it lower in the tank where the flow isnt that strong and for now its doing better.

And the new start as of 4/4/12.

My tank is a 76 gal 1/2 circle tank with LED's lights. It was 90% SPS.
Now it will be 99% SPS unless I pull the plug on the whole thing if I cant get things to get back to normal.
The tank has been up and running for over 4 years now.
I use to run the tank at
ALK 9 to 9.6
Cal 460
Mag 1350 to 1400
nitrates 0 to 5
Phos use to run 0 to 0.11 on my hanner checker.

Then new perameters are a litte off
As of 4/11/12 (I will be checking them all today)
ALK 7.05 I dose to bring it up to 9.0
Cal 500
Mag 1400
Nitrates under 5
But phospates were up to 0.21
So I put fresh GFO in Wed so I will see where it went today.
But thats why Im thinking the gfo's Im using arent working that well so that is why Im thinking of going to the XPort PO4.
The PO 4X4 didnt nothing but mess my tlf reactor up...

But are they doing anything for your phosphates?
Cause there claim to fame was nitrates and phosphates.
That is why I went with them kill 2 birds with 1 stone!!

A friend of mine did the same thing took the bio pellets out and saw better color and polyp extention just a few days after taking them out.

Im not saying they dont work or that they kill anything. But I dont want them in my tank.
You can try it with the sps just take it slow and watch what happens every time you put a new frag in. Thats the only way youll be able to tell if they will work in your tank.

Thanks for the advice tynman. No, you're right. I use two different companies biopellets (one company on each tank) and they have never lowered my phosphates that I've seen. Once I realized this I put chaeto in my sump with a 5 dollar light. It grows like crazy and my phosphates, and more importantly all the algae, has diminished to near zero. (hoping for zero over the next month or so). I've got it down to wear I only do a water change every 6 months or so and have no phosphate and nitrate issues. I hoping to take this knowledge and set up into an sps tank. But I want to make dead sure that the biopellets won't damage my sps.

This is totally off topic and I apologize Dan.

BP will remove NO3 at a rate of approx 16 parts to one part PO4, IIRC. So if your nitrates are low and your phosphates high, it will not reduce your PO4. You will need to run GFO for the PO4. I have been running pellets for almost 2 years now, they are not miracle workers, they have limitations. The bacteria mainly consume nitrates but also some phosphates, but the proportion is not equal. It is no different than VSV, you may have to incorporate GFO to keep the nutrients where you want them.

As far as hurting SPS, no, they should not if used correctly and they are not allowed to remove too much, I had that problem when I first used them, I almost lost everything because of running too many. Keep in mind the product has only been used for a short time, the long term effects are not known. Some people have had issues, some have not. No two tanks are the same, so what works for me may not work for you.

Well I wish you luck with the sps tank. I dont know if you can get away with 6 month water changes with sps. Hope you do and then Ill use your formula cause I had it to every 2 weeks a 20 to 25% water change.

Yes you are right. I had to run GFO's with the BP and still couldnt get them down to 0. So why not go back to what worked for me...
And yes your right about what works in my tank wont always work in your tank.

Randy I believe it was in the original BP thread. Do the bacteria not follow the Redfield Ratio? I know it was suggested in one of these threads. Teach me Master. :-)

No, bacteria that potentially perform anaerobic respiration will potentially have far more nitrate consumption than the redfield ratio indicates because they use it as an electron acceptor (essentially, as a source of oxygen):

This is a typical process:

organic + 124 NO3- + 124 H+ → 122 CO2 + 70 N2 + 208 H2O

I see that as a good thing, unless your PO4 is high and your NO3 low. I spent a minute searching for where I first read that, there are posts all over the place stating the 16:1 ratio of uptake with carbon dosing. You gotta love this place, the more you think you have learned, the less you actually did. :-) Thanks for the education as always. So tanks that have an imbalance (so to speak) of PO4 to NO3 are limited to using other methods such as GFO to reduce the PO4, if I understand the process, and carbon dosing is not going to help much.

Yes, that's why a lot of folks (myself included) find GFO is useful along with carbon dosing.

The oft quoted (and widely misused) redfield ration of 16:1 is an open oceanic average. Different organisms, and different systems of organisms can have hugely (were talking orders of magnitude) different ratios

Thanks Bill, and I am actually glad it was brought up, the fact that the bacteria can actually chomp on even more is a good thing for most people as I believe most people have more NO3 than PO4.

Now that this thread has been derailed from it's original intention, (sorry) I am wondering if the anyone feels that these products are no more than repackaged existing methods with a shiny new name? They do seem to work but that didn't surprise me either.

I'm bumping this up to see if people are still using these X-port NO3 and PO4 products. I'm considering trying these products because I'm tired of my GFO and GAC turning into solid clumps from my Vodka dosing.

I didn't think vodka dosing would cause GFO and GAC to form a solid mass. I've seen that from alkalinity dosing.

Any word on Xport po4?? My LFS switched all there accounts to it. Not because it's 500 times more effiecient, but because it is 500 times easier to use. No need to adjust for flow rate changes as the media clogs! I'm going to give it a shot. May make my BRS dual media reactor actually useful for 2 medias rather than just double GAC.
