Bio filtration, what do you use?

[VelvetAirwaves]

Hi all, as we all know biofiltration is a very big part of our reeding hobby, I would like to know who uses what and are the results that you have gotten satisfactory? (Excluding live rock)

I personally use Bioclean which is a combination of bio digest and bioptim.

So far the results for the past year are alright, and I manage to keep no3 below 10 ppm.

i've been a fan of seachem purigen since i started using it last year in my fresh water set up.

in my new 34L tank, i started using it when my tank's cycled is done.. at that time my no3 was 40ppm. which is really high.. probably due to the cubes of mysis shrimps i threw in weeks ago..

so i added in seachem purigen (half bottle of the 250g bottle) and within 1 week, no3 drop to 20ppm.. and again, 1 week later, i did a 20% WC and one day after the WC, i measured my no3 to be 0 - 5ppm.. cant really determined either because the API color chart shows 5ppm when u put the glass tube against the white back ground but 0ppm when u hold it up right..

i also keep biohome plus in my hang on filter.. together with rowaphos.

Haha, just to clarify, using nutrient absorbing media falls under chemical filtration, but since the topic has been brought up, I use pura complete, so far the results are satisfactory, I am able to keep po4 and no3 at a minimal I.e below 5 ppm.

I believe alot of the reefers use chemical filtration media as well, but in my case, chemical filtration is used as a back up, should there be a spike in nutrient level that the bacteria is not able to handle, the pura complete will. So far so good!

Is there actually a need for chemical filtration is a debatable question.

im so sorry! i misinterpreted your question.. i see the word filtration and immediately thought you were asking what we are placing in our filters..

It's okay! I've been wanting to try bio fuel, does anyone use that?

I use that b4 seem not really effective in my FOWLR but dunno for reef tank...If for me I would choose the sulphur to denitrate... biopellet and PO4 also recomended.

Can keep my tank below 20ppm nitrate after 3 mth never change water due to oversea attachment and my bro feed the fish everyday 3 times also...and also my skimmer not even skimming 500ml after I came back to check everything including the parameter
