Upgrading filter media in my Fluval 307

[Calamardo Tentaculos]

Hi all,

Having read the previous threads on this forum, I am thinking of replacing the filter media in my fluval 307 to increase its efficiency. Currently it is split between foam on one end and seachem matrix + filter floss in the baskets.

From what I have read, I should use K1 media in the baskets (fluval has three baskets) to create a fluidised bed of K1 media, is that right? What should I use in the other section where Fluval places foam in it? 30PPi foam?

Appreciate hearing all your thoughts on this.

I don’t think you’ll get a bed of fluidised K1 inside of a filter, so probably just best to use 30ppi all the way.

The media in an aquarium filter is the most important variable when setting up a filter.

Honestly? I'd just take the filter floss out.

It is fine as a static filter medium.

However the foam will have to be cut to fit exactly into the basket so that the water flow is forced through it, am I right?

Yes.

This also what I would do 🙂

Something similar to K1 comes standard with the Oase Biomaster filters. It works fine as a static media in the filter, in my experience.
That being said, I don't think there is any difference at all in biomedia - except maybe for how many years it lasts, and how much debris it might trap.
