Filter Media For Heavily Planted Tank

[craigybaby37]

Ime soon to be setting up a heavily planted tank and ime stuck with what to use for my filter media. I will be using a CO2 system so the probe and bubble difuser can go in the sump.

I will be housing everything in a 12 gallon sump here is a picture of the sump atm with all my marine stuff in but you can get a good idea od the size of the chambers in the sump.

All help will be much appreciated.

Depend on your tastes really. I would fill the first chamber with pot scrubbers or coarse sponges. Some sort of bio media/ceramics should come after that, last you should have filter floss. If you have space between these layers Then I just use random sponges and stuff I got laying around.

I agree with Mikaila. Pot scrubbers give you some of the highest bio surface area you can get in larger filters. Another biomedia often used in sumps are plastic bioballs, used because they are usually much cheaper than the equivalent volume of ceramics like Seachem Matrix and of course you've usually having to buy fairly many for a sump.
