Since my tank has only been established for about three months in which time all the water entering the system came from I high quality RODI unit in an area of the country with very low metal content in the municipal water supply, it would seem to me that my risk of increasing the amount of free toxic metals would be minimal. Would you agree? Also, is there a target ORP range? I have continued to get conflicting answers to that question.
After reading the positive feedback on these pellets, I've decided to order some for my tank. I have some quick questions, though (sorry if they've already been answered). I currently have GAC and GFO in two TLF reactors, which run in series and are fed by my return pump. I would prefer to replace the GFO with the pellets, but I see some people run both. My questions:
1. If I simply replace the GFO with pellets, can I continue running using the TLF reactors in series (GAC then pellets then output to the skimmer intake)?
2. Should I add another pump and run the two reactors seperately?
3. Or, should I continue running my current setup and add a third reactor for the pellets with its own pump?
I really prefer to keep thing simple but want to do whats best. Thanks for the help.
Jon Warner reccomends you run it in it's own reactor with around 100gph flow. As far as GFO goes i ran it until my Po4 was undetectable with the Hanna meter PPB and then removed it. The EB has been holding it at around 4PPB which is pretty good IMO without any help. JMO

hey Bill! glad it's working out for you. I am seeing good things on my end too at 1.5 weeks. I am at .03 PH4 and waiting to go undetectable before pulling GFO off-line, although I think it is already exhausted anyways.
So would 4PPB be .04 on a hanna?

Took my GFO off line the other day and my po4 is still 0.00 on my hanna checker. So no more expensive GFO for me!
WEEK 2 UPDATE
Started with 500ml the first week and added another 500ml for the second week.
PH4 have dropped from .08 to .02
N03 remains the same at 2.5ppm
I definately see an increase of skimmer gunk!
Good deal platax!!!
Noticed any extra brown or green diatoms?
Nope nothing yet. I had a bit of cyano that has actually gotten better.
How's your doing? Any change in your corals?
Does phos. usually goes up then come back down after a month. When I strarted on Mon. phos. was .06 on a hach phosmeter. Today it goes up to .09 should I start using GFO w/ the pellet again.
.
...The 3rd week I decide to try something else, so I turn the valve down so the pellets barely stop moving. I wait 2 days and check the PO3 and it dropped to 0ppm. I didn't know if this was b/c I slowed the flow thru the reactor or what. Later that night I put the flow back to full blast. the pellets are tumbling like crazy again. I check the PO3 the next day and it was back up to 5ppm. I decided to try it again slow and no tumble.
Today is beginning of week 4, and PO3 is 0ppm and PO4 still 0.00 Hanna Checker....
Anyone else have similar experiences with decreased flow?
