Now try soaking a pinch of flakes in some ro/di for a few minutes, strain, and retest. (it is supposed to be less po4 )
Assignment complete, I soaked it in distilled, for about 1/2 hour (got busy), strained it and put it in some tank water for about 10 minutes. po4 not soaking in fresh water 10, after soaking it in distilled .5. major difference :bouncebox crazy.
