Phosban 150 question?

[Robka]

I know you can run GFO or carbon in this reactor, but would it be ok to fill half & half with GFO on bottom & carbon on top (since the flow is bottom to top) with the disc sponge separating the two materials?

Thanks for your help,

Robka

I know using GFO is not that unusual, someone must have some idea, please

the red disk on the phosban 150 is fixed and you cannot adjust/move it to the center like what you are saying.

I was talking about the sponge disc. I bought some extra to use that in between the 2 materials.

I would think that would separate the two well enough and with the slower flow used with GFO, I thought the carbon would work in there as well. I have seen people link two of the 150 reactors together and put carbon in the second one, but I don't have enough space so that it why I am brainstorming on this setup?

Thanks again,

the GFO needs to be fluidized and on bottom of carbon it won't and on top of the carbon the sponge will be pushed up and prevent it. you don't have to run both 24/7, run one for a few weeks, then the other, so if you only have room for a single don't mix them.

I am pretty sure you need a firmer separator (like the red disk on the TLF) if you want to use two media simultaneously. the via aqua media reactor has a disk that can be moved anywhere on the center tube, so you can use that instead of the TLF. I think you will still be able to get the tumble on the GFO with it on top. You can just use enough media so you can change both carbon and gfo at the same time. your other option as mentioned above is to use one media at a time. GFO can bring down your po4 to 0 in a few days.

I run po4 and carbon together in reactors all the time. No separation via sponges needed.

Thanks for all your help guys

How did you do that. Just spit the amount in half?

Should I run carbon on the bottom & GFO on top so that it tumbles? Also why does it need to tumble? Isn't the water flowing by the material good enough for absorption similar to using a filter sock? The reason I was asking is that I was thinking of purchasing this GFO (http://www.bulkreefsupply.com/store/3-pounds-half-gallon-bulk-gfo-high-capacity-ferric-oxide.html) & it's size doesn't seem to lend to tumbling? I guess I thought the reason you wanted the granular GFO to slightly tumble was because that was an indicator of proper flow rate?

Thanks,

I'm also running both Rowaphos and active carbon in my single TLF 150 reactor. IMHO, both will mix eventually when they trumbling so whether which one put in first doesn't really matter so long they perform what it needs to perform :bounce1:.

The issue is to get gfo to work properly it needs to tumble or look like its boiling. With gac you dont want it to tumble cause it breaks up easy. I run gfo in one and gac in the other since the require 2 different flows.

Sorry for my ignorance,but what is gac? Is that a different form of carbon and what is the flow requirement for it?

Granular activated carbon. Low flow the slower the better the contact time

If GFO is supposed to tumble then how do people gets result when placing in a filter sock?

I guess I thought GFO was also supposed to have a slow rate, also? Sorry for so many questions, but I am really trying to get my reactor dialed in correctly and since my space is limited I want to get the most out of my single reactor.

Thanks for all your help,

The tumble is to keep it from clogging. In a media bag you can get results hiwever its not as effective because the water will flow around it rather ghan through it. Least resistance.
