any bro is using active carbon directly in shrimp tank ( not at the filter ) for shrimp tank? I would like a second opinion as NA boss recommended me to do so.
Please share experience.
Never create what you can't control
Any difference if used in the filter or in the tank? Hmm... never tried but don't think there is.
Active carbon is used to absorb any impurities and anything that may be toxic to your faunas. If that is the function, does it matter where is it being used?
Aesthetic wise, it may spoil the look. And it removes nitrate, which effectively starves the plants from the nutrient.
oh that is because i am only using a hang on filter which is full of sponge and biohome and ceramic rings so i have no choice but to chuck one carbon bag into a corner of the tank.
I have not heard of the A carbon removing plants' nutrient though... but i rate my shrimp survival over the plant...so i will most probably add in. but i think better to monitor furthur since the shrimp are doing ok. then better dont add or change anything.

Normally people will put in the filter to enable water to "Squeeze" thru the carbon to make the water look crisp and clear.
It also helps to remove smell from the water

Yes, you are correct. It should be nutrients/fertilisers instead. To what extend or detailed analysis, I cannot be sure though.

Activated carbon performs other important tasks in the aquarium as well, removing toxic dissolved gasses such as hydrogen sulphide and methane, which result from imperfect water circulation. It acts as a catalyst to quickly convert dissolved chlorine gas to relatively harmless hydrogen chloride. It provides crystal clear water by removing minute suspended solids and colloids - those particles too small to be trapped by filter floss. It helps defend aquarium life on some occasions of accidental introduction of toxic substances such as pesticides,paint fumes,cigarette fumes and the like.
It seems that AC is quite useful in aquarium,Another web site also mentioned that it can remove a certain level of copper, magensium etc however it was proven to remove iodine too which is quite essential for shrimps ...so really i am not very sure about the the use of AC in a shrimp tank
Another research study also shows that the advantage of placing AC in the filter over direct placement in tank is not obvious.

to be frank skysky,
i dont use carbon at all..
For me, I stack my biological filtration (biohome plus) on top of active carbons which belong to the chemical filtration group. This will ensure my biological filter bacteria don't get starved of nitrites, nitrates and ammonia since certain brands of active carbons can absorb the 3 "nutrients". I do not want to cause a "famine" and kill off all the biological bacteria and regret it when I stop using the active carbons.
I use active carbons mainly for aesthetic reasons since they help remove odour and colours from driftwood leeching and waste products of fauna. My water is crystal clear all the time. Do remember to change the active carbons every 3 months as they may reach saturation stage and start releasing everything that has been adsorbed. Can be quite a killer for sensitive fauna like shrimps.

Hi All
Just to sidetrack for a bit, I am also using a hang on filter and I find there is not enough space for biohome plus filter medium. I therefore put them in a filter bag (that comes with biohome) and put in in one corner of the tank. May I know is this effective in growing the BB?
Thanks to advice.

stacking in a corner might not be as effective as with the water flowing thru through the media.

not really, over time the difference is not significant. I read it from a research paper done and published online.
Hi skysky
Do you mean that over time, the result will be as good as putting the biohome in a filter box?

Biohome and AC serve 2 different purposes. AC is for absorbing/removing odour, colour and small traces of toxics. Biohome is for BB. For AC the effect of removing toxic is not of great difference in a medium size tank eg a 2 or 3 ft tank.
Nevertheless, both mediums are best place in the filter if given a choice.
what i mean is there is no point placing biohome or ceramic in a corner of a tank... no purpose in that
ah i see , me bad ..sorry, i thought you are talking about AC

Nitrifying bacteria colonises everywhere, not just in filters, as long as they get oxygen and food.
As I undstand it, Biohome or ceramic contains higher surface area and this enables more bacterias to colonise the surface are, regardless whether they are placed in the corner of the tank or in the filter.
I am not wrong, the only difference is that placing it in the filter will ensure that they get the oxygen and food that they need as there is always water movement. In the corner of the tank, oxygen and food may be insufficient to sustain a large colony but a smaller colony should still survive.
First of all, have to understand what is the purpose of you adding active carbon. The speed of action of putting in tank and put in filter is different.

Hi bro silane
I added in as i suspect there are some traces of copper in my tank as i have 1 or 2 shrimp death every alternate days. but the rest of the shrimps are breeding well.
regards
hi bro,
If you want to remove copper, and the quicker the better, so get them into your canister filter.
Note that AC changes water parameters, use it with care.

noted. i am also adding EASYLIFE that will binds heavy metal including copper...will see how.
By the way, in what way does AC affect water parameter ? PH?
Thank You
