High Nitrate, NO Phosphate

Thanks! I'm increasing feedings but not noticing any increase yet. Trying not to be too drastic, but it seems like I may need to start dosing. I have Spionid worms in the sand and a hungry Nassarius snail that both grab most of the leftover food, so it must be really difficult to overfeed.

Feeding more is often the easiest and fastest. Dosing N and P also works well.

I would not feed more as a solution unless both PO4 and NO3 are below where you want them. If at any point, only 1 of PO4 and NO3 is too low, then dose just the one that is low. Otherwise, it will take a long long time to get them in balance.

He said both were low. This is not the situation of the op.
