Plants On Top
I notice it is becoming more and more popular to add a few house plants with their roots in the tank water. What about taking it a half step further? instead of just dangling the roots in the water, or the roots in some media in a basket hanging in the water, might it be effective to say, fashion a trough to hold the media or clay balls and pump the water through the roots and media from one end of the trough to the other and back into the tank? Maybe even a filter sponge on the front or back end? Might this help circulate the water better over the plant roots and help filter the water a bit more for the tank as a whole? Just an idea. Has anybody done this? Would love to hear your thoughts and/or laughter!
