Hey guys, I need to change my FX5 around. I currently have all three trays full of Pond Matrix and Matrix with a blue filter pad sitting on top of the matrix in the top of the first tray. I ordered 500ml of Purigen as I really think I could benefit from it. I was planning on running about 250ml in the FX5, leaving me with 250ml to swap out while I recharge the Purigen. My Bioload is fairly high due to the amount I feed, but not necessarily due to my stocking list. My nitrates are usually around 40-60 a week after my 50% water change. I'm assuming two trays full of matrix / pond matrix would be fine? I also run a Hydro Sponge V (rated for 125g tanks), surely between that and the matrix I should be good.

What I think would be best is to put the Purigen in the bottom tray and leave the matrix in the top two trays, or should I put the Purigen in the top tray under the filter pad?

I don't use Purigen, but I would think it would be more ideal at the last stage(bottom)
