So the black sponge I got is supposed to use for thr bio max stuff... one item goes in the bottom slot and one goes in the top slot not sure what else it's used for....Shoot I just realized that bag has bio max in it.
Ok this is what I would do.
1) On The BOTTOM of the filter use the carbon sponge that is in there now.
- If anyone thinks this is a bad idea please speak up. This is the only seeded material left.
2) Cut the white sponge to fit on top of the carbon.
3) place the biomax bag on top of the white sponge. Thats it for now. it can stick out some but not a lot.
Replace the carbon filters one at a time with chunks of that black sponge you bought. do this over a couple months. If only one carbon fits just use one. Its better than nothing for now. replace it a month from now.
