I have found floating water sprite a VERY efficient remover of nitrates as noted. However, I now have a near constant struggle to keep adequate nutrients in the water. The other plants which stay longer (i.e.- the water sprite soon must be removed or over grow the tank) tend to show the most accumulated adverse effects (phosphate deficiency, etc) presumably because they remain behind. Have others encountered a similar downside? If so, any suggestions on achieving a better balance? Thanks.
