Waiting for my sunsun 403b to come by mail. Has three trays for media. Flow goes from bottom to top. What should I put in each tray

Bottom = Mechanical (Sponges and foam pads)

Middle = Biological (Pre-filter and Bio-Rings)

Top = Biological/Chemical (More Bio-Rings, Carbon, Purigen ect..)

What is considered prefilter

This is how i would do it.

Bottom = mechanical media (course sponge and bio-rings)

Middle = biological media (Seachem Matrix, or Eheim Substrat Pro, or small Marine Pure spheres)

Top = polishing media (fine filter pads. With or without Purigen/Carbon)

My 2 cents.

That's basically how I run my canister.

I'm not too sure myself... All I know is that I have some.

I think it has something to do with porosity.
Pre-filter has larger pores to allow for more gunk to get trapped.

There are a ton of different bio filters.

The Marine Pure which was mentioned is probably the best of them.

You can also get plastic ball type things which people use in fluidised filters, not sure how they would work in a canister.

Plastic bio balls have such small surface areas, I personally would not bother for a canister. (Even the plastic bio balls with sponge inside)
Better for large sumps in my opinion.

Marine Pure has highest surface area of the lot, but it slowly breaks down over years. (Mine started to break down by around 5% in first year)

Eheim substrate Pro is also top quality, but internet states it clogs easily after a few years. Not sure if this is true or not.

Seachem Matrix, I can't find any major faults yet. Has less surface area than Marine Pure, but Seachem debates it has higher surface area than Eheim Substrate Pro. Although Eheim have once stated their media has more (who do you believe?) So Seachem payed for a lab test and posted results on their website. Im not sure if Eheim responded. Seachem Matrix probably the oldest technology though as its been around for a looooong time.

Ceramic noodles is basic bio media. Better than plastic balls, but has alot smaller surface area than the other top brands mentioned. I just use it for course mechanic filtration along with a course sponge.

Hope that helps.

The filter will come with media. I got pads, carbon, bioballs, ceramic rings and I think sponges too.
