Canister layering

[armageddon]

benny brought something up which i am curious..
jap matts. how are their effects? isn't jap mats corse? so why use them AFTER wool? care to share why it is be before wool? what is your consideration when layering it in that manner?

Jap mat effect is debatable. Many fish shops and farm, use them solely without other kinds of bio media. Some hobbist say it is useless. Personally, I think jap matt would be inferior to CR or other media if you are comparing it per cubic volume against its' bio filtration capability. The same can be say about their pricing, per cubic volume other bio media is much more expensive. So imagine for the same amount of money, how much jap mat you can buy.

If we imagine each media as a factory, the Jap mat factory might be a less productive one. But say 1000 dollars can buy you one bio homme factory, which produce 500 toys per month. The same $1000 can buy you 10 jap mat factory, which produce 100 toys per month (which is significantly less than biohomme factory). But their total output is 1000 toys per month, so it might be more effective to use jap mat factory. However, as hobbist we have space constraint. So we do not have enough land to build 10 jap mat factory.

I hope you get the picture. To summarise, if you have the money, buy expensive but proven/quality bio media. The rest of us with no money have to make do with what we can.

You can use it before wool if you plan to use it as a coarse filter with bio filtration capability. I put it after wool for pure bio filtration capability and to provide structure and support for wool which gets soft and "flatten" over time.

As i have no test kits i am unable to provide you with exact figures, the factory example is just to prove a point. Plus to make a unbias result, i will have to use a purely jap mat against another setup using a pure comparing bio media ceteris paribus.

that is an extremely detailed explaination and example. thanks. just curious why it is placed after wool as i understand the point you have mentioned about the factory production thingy too.. haha.. good consideration. i may consider a combination of jap matt too for my future setup. something which i have never considered before.
