So after a long search I found a local place that sells pfs. Now I have a tank with LOTS of vallisneria in a fine gravel substrate. The gravel takes forever to vac when I do my water changes and then I have to replant all the plants that get uprooted. My question is if I take out all the gravel and replace it with the pfs will it affect the plants? Pfs should also be a lot easier to clean am I right?
