Photobucket - Watercress Island
Your model will work really well for the parrots feather on the
surface of my upflow barrels on the berm. I used to rest my top
plants on the bags of filter strapping tape, but I am taking them out
as the roots of the veggie filter plants provide more than enough
surface for bacteria. I had also hung trays for the plants. I like
the floatation much better.
Thanks
Jim
