i'm sorry for the mistake in bigger biohome has more surface area. it is the same as smaller biohome. the bigger biohome has higher porosity about 10% more for better gas exchange. so i guess even though the bigger biohome is larger in physical size, the pore is bigger for better gas exchange hence the surface area is not more than smaller biohome and instead it is the same. the bigger physical size is sort of compensation. it is like having a few smaller biohome in 1.

for matrix, i guess pond matrix is having lesser surface area than matrix though the physical size is larger is the same as biohome. maybe the pore is much bigger than the difference in biohome as it can be use in the pond and to avoid clogging the media. normally matrix is after a mechanical filter. most likely i will try matrix for my next tank due to better cost efficient than biohome.

Actually got more of it now than biohome cos gray biohome breaks down a lot.
JBL Micromec wears down a bit.
Red biohome lasts well, almost zero wear.

thanks for the info on the biohome standard. didnt know there is a diff between this and plus. i'm using plus and is pretty good after few years of usage. how about the matrix? is it like biohome plus? may i know how much is jbl micromec? i will read up on this. thanks.

Matrix is lighter, good for ohf.

JBL Micromec I can't recall pricing.

Qian Hu OF 3DM filter media looks promising.

I haven't used it yet.

The volume of water absorbed gives rough guide to the biofilm potential surface area, the speed with which the water drains out gives indirect indication of porosity.

Representatives from Qian Hu updated the guests on the newest products from Ocean Free.



This Hydra Filtron is an interesting new product from OF. They had incorporated their HydraPure technology into a canister filter. On top of the HydraPure addition, this canister is filled with many features to enhance the canister filtration experience. Filled with 3DM premium media, easy priming, quick start, low power consumption, high rate filtration. Thumbs up!



Inside the OF 3DM filter media.



Filtration sumps filled with 3DM. Professional exotic fish breeding set up overseas.



Density comparison of filter media. 300g of different filter media were filled into the measuring cylinders. The OF 3DM filter media takes up the most volume, indicating the lowest density. This means more pore space within each bead of filter media, more space for beneficial bacteria to grow. Also means less weight, which is important for users of overhead filters.




Absorption comparison of filter media. 200ml of water was added to 250ml of filter media. The cylinder filled with 3DM had the lowest final volume (270ml). This shows that the 3DM is able to absorb more water compared to other filter media. The capacity to absorb more water indicates higher porosity of the media, higher specific surface area of the media. Basically, more space to hold more beneficial bacteria within the same volume of filter media.

In simpler terms, a compartment filled with the 3DM filter media is able to offer much more space to grow more beneficial bacteria.

My guess is for bigger piece the only way to have more pores (hence total surface area) than a smaller piece will be either using a different spec material or a different steps to manufacturer (e.g. introduce more and perhaps smaller air bubbles). I suspect for more pores will mean the end product being more brittle.

[Ong88]

Yes
Most absorbent and porous in my rough non scientific observation is marine pure.
It is not brittle when dry, but when wet it is very friable and crumbly.

Now I make sure marine pure is dry a day before I handle.
The balls when wet are less fragile than the wet 8 inch square bricks.

I hope in future they can develop a convenient product or material that can somehow house anaerobic bacteria to remove nitrate effectively. So far I am not convinced by the products in the present market.

Is this good? Can be recharged unlimited times.

What's so difficult about regular WCs?

Money plants, guan yin teck etc for me.
