the sump is empty (i was very fortunate!),
pursuant to merrill's advice, i was removing all my sand and rock from the sump--i was advised that the rock and sand in my sump were causing nitrate and phosphates.....so the sump was completely emptied (wet dry vac!)
...and this happened while i was trying to reattach an external pump
so, marco, now that i have an empty sump....would you still start fresh (i am leaning in that direction)
