I am looking for some advice on my planted set up.
I am currently running the following:
Fluval 306 canister filter
Tetra whisper air pump and small air stone
Coralife 48 inch dual bulb T5 HO lights
Glass aquarium top
Flourish 1 dose a week
Flourish Excel 5 doses after water change & then 1 dose daily
Flourish Root Tabs
The main problem that I am having is that I am not seeing any significant growth on any of my plants. I am also noticing that some of the plants have black/brown spots on some of the leaves and stalks. I am looking for advice from some experienced planted tank keepers. Do I need additional ferts? Am I missing a key component?
Thank you all for your responses
