Pothos in the filter outflow for nitrate, anyone actually seen a difference?
Saw discusdan's nitrate thread and it got me thinking. I've got a long pothos cutting with the roots dangling into the sump of my 55, no other changes. Nitrate was 15 a couple weeks ago and I haven't tested since. Has anyone run emersed pothos or similar and logged real numbers before and after? Pic below of the sump setup is not mine yet, still deciding where to hang it.
