Is there somthing wrong when you do a 50% WC and the nitrate levels are still the same??? For me after the Wc the nitrate somehow drops down which is weird.(after a couple days)
does that mean my sump is not fully cycled?
Is it possible to the pothos in a sump?

Try cleaning out your filters, there may be trapped food or a rotting fish under decor or in substrate and as said above test your tap and vac your gravel!
They grow fine in sumps!
