Fluidised reactors

Hi, I have just bought a fairly tall FR. JUst wondering if it is ok to dump charcoal and rowaphos into it instead of using separate FRs. Thanks.

it might be quite a waste as charcoal and rowa exhaust at a different rate so when changing the media, you are wasting a bit, nevertheless, it is NOT good to fluidise carbon as the media is brittle and by fluidising, you cause them to knock against each other and break up causing carbon powder to flow into the sump,,, bad idea..

Wow, thanks !! I'm glad I asked first. Will fill up my FR with rowaphos only.

Hi,

Correct me if I am wrong, what you are saying is that the Carbon should not be put in a FR? If so, where should I place them?

Put in separate FR, I had similar idea last time but I was told that if two different desity material mixed in the FR will create media destruction on the lower density material. This detruction will be fine particle and may be pumped to your water.....correct me if I am wrong.

carbon should never be placed in a fluidising equipment.

as i've mentioned, the media is brittle and by fluidising, you cause them to knock against each other and break up causing carbon powder to flow into the sump.

just have some in a mesh bag and put the bag in a high flow area in the sump and change it once or month or when you see that the water is yellowing..

i disagree. depends on the type of carbon you are using. If you are using rowa carbon, it is pelletised so no disintegrating whatsoever, and safe to put in fr, another good media is Chemipure. Best option available. No phosphate leaking at all.
