Any fishkeepers here? Saltwater or freshwater

I'm not sure how plants could absorb ammonia.

Everything I've ever known about marine plants anyway is that they only work with Nitrates. Things like chaeto algae, calupra and mangrove plants all serve to knock your nitrates down but they don't do anything for ammonia.

Nitrates aren't really that big a worry though, especially not for fish. Nitrate levels can get insanely high without having an impact on your fish, especially if you keep everything else within acceptable limits.
