Seeing really slow growth on an ADA tank.
Here's the tank in December:
Here's how it looks now:
No trimming of HC in between. Very light pruning of hairgrass.
I'm not certain why the plant growth is so slow (or is this normal growth?). I'm using AS Amazonia, dosing 1 pump of ADA Step 2, Brighty K and Brighty Lights daily. Light is 5-6 hours as is CO2. Drop checker is on the lower side of lime green.
Water changes are twice a week 50%.
Am I perhaps neglecting some vital trace elements or merely expecting too much?
