Start with lower light for easier success; most plants will adapt. Algae = imbalance, not “too much blue light”.
Low = budget LED/domestic fluoro. Medium = T5/T8 or aquarium LEDs. High = full-spectrum premium LEDs.
Blue light isn’t your enemy; poor balance and excess organics are. Keep maintenance and water changes regular.
APD grows many species emersed for stronger transition underwater — just like seasonal cycles in nature.
