They are at 200+ at the top, while other spots are only at maybe 20-30 umols.
I moved all the white Anubias up to the top, they do best there.
Water changes, add ferts, good CO2, algae eaters(better them than you), and high plant biomass. The tank languished for 1 month, then everything settled after the new redo mostly for new sediment root formation and bacterial layers to form again.
EI dosing these days after starting at 1/2 that amount prior.
I dose macros 2x a week, then traces most days.
Not much else, big water changes mostly.
But I've gone a month without one without much issue. Still, I prefer to stay on top of things for obvious $$$ cost reasons for the plants.
