Phosban reactor question

[sully08]

I am getting ready to set up a phosban reactor. Do you run these reactors continuously or just when they are needed. Would it hurt to run them steady.

Continually for your reactor. Nice slow bed movement, just enough to turn the media over

I run my carbon at a slow flow, just enough for a small tumble at the surface of the media and for phosphate I run it with high flow.

As per all my knowledge all media is to be slow tumble.... But you can double check anything and all advice from anyone. Lol

Hmm ... maybe we could get some clarity here
I don't want to start an arguement but I've seen the opposite recommended

In the quote below ( taken from this thread ), Doug says higher flow for carbon, and lower flow for gfo

I've been running my carbon at a 'high boil' and my gfo at a more conservative 'rumble'

I've read 'boiling' carbon can allow particles to enter the DT and cause HLLE, so my carbon exits before my socks ...

What's the correct flow rates ?



Edit: To answer your question;
It's up to you. I run both of mine 24/7 but you could run them only when you need them

I thought carbon was not to be tumbled as it grinds it up, I pack my carbon between sponges to keep it stationary.
I soft boil my gfo just enough to keep it moving throughout the reactor.

+1 ... I am under the impression that tumbling carbon erodes it which releases carbon dust into the tank. I have read some primary literature that showed the carbon dust can cause a disease in some species of fish. I have always fixed my carbon in place (ie inside a bag or between sponges) and fluidized my GFO at a light tumble.

So what I've read, and been told, about using 1 cup of carbon in a TLF 150 for my 110g total system is not the best idea ...
I see the point where there will be no concern about carbon break-down and subsequent HLLE, or other issues, with a full reactor

Guess I'll be filling my reactor to the top from now on
