change of filter pads
« on: March 14, 2010, 06:55:18 PM »

Done the 30% waterchange, rinsed the filter-carbon pad in a jug with "old' tank water. It was filthy, now only a brownish colour... how often do they need to be replaced?
Once a month perhaps?

That's what I do. It may need to be done more, just dont replace them all at once. I replace half of them one week and then the other half the next. this lets the bacteria really settle on the first set of filter pads before you change the other ones. At least, thats what I do

Decided to change one filter-carbon pad today.
The original one is pretty yuck .

How often should we replace the ceramic noodles?

"Ceramic noodles" shouldn't need to be replaced much, especially if they contain most of the beneficial bacteria (which they are for) but I think rinsing them in tank water every six weeks might be good to do.

Another thing, you've got charcoal or activated carbon in your filter? This is actually something that you should use rather after medication since it will absorb the chemicals. Carbon/charcoal tends to get dirty very fast, and then it does more harm than good.
If possible, I would exchange this to a sponge or something else of similar size that would fit in the filter. Embarrassing as it is, I don't know what you mean by a "filter-carbon pad"...ehem... what does it look like?

There was some activated carbon in my filter too when I bought this tank but I kept it in a plastic bag instead of in the aquarium d: Mainly because I know that it's not the best filter media you can have.

Please do not be embarassed,
I should have said carbon wool cartridge, it is used for the AquaOne 380 which we got a few weeks ago:
AquaStyle (AR) 126 Carbon and Wool Cartridge - 1c . It is like a carbon tray covered with that wool, all one piece...like a coffee pad
Works in AquaStyle 126 & 380 Series. Underneath I do have an extra sponge, it covers the "noodles".
I attached a picture. And yes, it has activated carbon in it.

Just had a close look at the Elodea, I threw a few pieces out, as the leaves were transparent brown, only kept the fresh green branches

Okay, so then I would really suggest exchanging the carbon to some other biological/mechanical filtration media. And keep the carbon only for rinsing out medication in the tank.

(Thanks for the pics! I've never seen anything like it :'D)

Nossie,
I disagree.  I have always used a carbon filter in my aquariums.  It keeps impurities out of the water.  The filter should be rinsed with tank water and put back in and changed monthly to every 6 weeks depending on if the filter is totally plugged or not.  You can tell if the filter is really clogged if the water isn't able to run through the filter properly and instead spills back into the tank.  Good filtration is important and the use of carbon keeps your water crystal clear.
As far as water changes and how much to take out, you should be testing your water BEFORE you do a change.
If your water parameters are good then you can do a small change if you want to, like 10%.  If nitrates are high or any other parameters then you may have to do a 20% or 30% change.

I have never used carbon in my aquariums, and the water's been fine without it (: And I motivate this with the fact that a filter media with surfaces for beneficial bacteria to grow along with regular waterchanges would be of bigger benefit for the fish than to rely on a charcoal filter. (Because of previously mentioned reasons.)
I personally won't use charcoal in my aquarium. Unless it's for a short period to get rid of medicines or other chemicals. And I will give this advice to others too, since I have seen that it works, and this is what I have been recommended.

I do appreciate your opinion though, no question about that (:

There is a big difference between activated carbon and just charcoal.
I do not recommend using charcoal.  The activated carbon is an excellent choice to put in filter media.
Bacteria will cling to the filter meda while the carbon takes out toxins in the water.  Makes the fish's life a little easier.

I thought they were the same thing! So tell me, please, what's the difference? (:
And if possible, would you tell me what kinds of toxins too? I'd actually be happy to learn a bit more about different filter media, since there isn't too much written about them in the books I look it up in. (Aside from the basic sponge filters, ceramics and then also the carbon.)

Activated Carbon has pores and charcoal does not.  So when it comes to fish keeping, the activated carbon will absorb gases and chemicals, thus making your water cleaner or sweeter...well at least sweeter smelling Smiley
The pores activated carbon has, allow it to absorb more organic chemicals.
 It will also remove small amounts of dyes, discoloration from tannins leached from wood such as driftwood decorations, as well as some odors. It's used in some specialized tanks for removing toxins produced by corals (also some fish species) in saltwater tanks. It can also remove some harmful metals in you tapwater (if these exist).
There are also toxins in the air if you use any chemicals, such as cleaners, perfumes and air freshners.  Carbon will remove any that inadvertly get into the tank.  Also anything that you have on your hands when sticking them in the tank for maintenance or hand feeding...such as soap residue or lotion, fabric softener or detergents.
You don't have to use it if you don't want to but I do because I like how sparkling clear it keeps my tank with no discoloration in the water and no bad odors.

actually I was about to start a thread on something so similar that I'll just hijack this one...... Wink
I was wondering too about changing the filters, more along the lines of is there any reason I should have to replace the activated carbon filter pad instead of just cleaning it and maybe boiling it and re-inserting? I know at work there was an account with an air conditioning unit that had a rack of activated charcoal filters between the pleated filter and bag filter banks, and that once a year, we had to pull them out and take them to get re-activated. This got me thinking, if that activated charcoal filter had to be "re-activated" once a year, why would my activated charcoal filter for my fish tank only last a month? If the carbon is still "active" then as long as the filter is clean enough to allow for enough water flow, why should I throw it away? Then again, maybe it's just too nasty and not worth it to clean.

charcoal, carbon, same stuff.....not really but when speaking of filtration media, I believe they're interchangeable.

Activated carbon, also called activated charcoal or "Activated coal" is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions.[1]

The word activated in the name is sometimes replaced with active. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2, as determined typically by nitrogen gas adsorption. Sufficient activation for useful applications may come solely from the high surface area, though further chemical treatment often enhances the absorbing properties of the material. Activated carbon is usually derived from charcoal.


Activated carbon (AC) filtration is most effective in removing organic contaminants from water. Organic substances are composed of two basic elements, carbon and hydrogen. Because organic chemicals are often responsible for taste, odor, and color problems, AC filtration can generally be used to improve aesthetically objectional water. AC filtration will also remove chlorine. AC filtration is recognized by the Water Quality Association as an acceptable method to maintain certain drinking water contaminants within the limits of the EPA National Drinking Water Standards, I also attach a couple of photos of activated carbon.


This is why I prefer to use a Activated Carbon Wool Filter Cartridge. It is also recommended by AquaOne Aquarium specialists.

I did change the cartridge, the first one we had was 4-5 weeks old and yucky. And the amount of poo left overs in the gravel !!! I vacuumed it out and rinsed the ceramic noodles in old water, washed the plants in old water too.
Now Humphrey and Hepsiba enjoy their clean home and you should see them how busy they are again Cheesy

just thought to let you know, if your filters look like this and you cannot get them clean, they should be replaced Tongue

That was great info Hanna! Cheesy
And Salty,  I was just about to write that I mostly prefer carbon cartridges because that is what came with my filters and for it being so easy peasy, and quick I guess I would prefer to just pop the cartridge out and replace it with a new one than to go with all that trouble of taking out the carbon, boiling it ?!? and putting it in a new floss pack.  Sheesh that seems more trouble than it's worth but if you're up for it.. Wink  Another thing is I would think that the carbon can only hold so many toxins before it would become ineffective.

That is a ddisgusting looking filter cartridge Hanna!!! Tongue Yea I think it'd be time to change it when it got like that (I change minee once a month, or at least rinse them out a lot in aquarium water!) Tongue when I do get a new filter, I've started letting the new cartridge soak for at least 12 hours, I think that helps a little.

I'm just curious why you soak your new cartridge for 12 hours?
You really only have to rinse it in aquarium water taken out of the tank and then pop it in the filter. Smiley

cause I feel like it helps a little. I don't like putting something in thats just been slightly rinsed. I might be over doing it (I know I am, just... shush... hahaha) I dunno. I wanted to see if it would really make a difference... Tongue

Ok, if your tap water contains any toxins or heavy metals and you soak a new filter pad for 12 hours, thus pulling any toxins and heavy metals out of the water your soaking it in, wouldn't it be better to let it pull toxins and heavy metals out of your fish tank when it is a fresh filter rather than already overload it with toxins and heavy metals when you put it in your tank? Huh
