Great thread! I've gone through a little better than half of the ~140 pages but still have a question! For those of you with pothos plants in their main tank, where the roots become completely exposed to air during water changes, do you find this is detrimental to the plant? I've read remarks elsewhere where exposing the roots to air once a week is like putting the plant through "transplant shock" every week and eventually it will wither and die due to this? Has anyone experienced this with pothos in your tank?
