20 gallon breeder seems to have algae issues whenever I go above 10 watts of light in the tank. Co2 Injected.
I'm currently on a 10 hour photoperiod.

I was wondering If I would get better results in color plant robustness if I just did a short but intense burst of light for shorter instead of slow but longer?

Tank is mostly just buces + some eriocaulons. I've noticed better buce color in higher light, which is why I'm asking.

So.
6 Hours (30 Watts) Vs 10 Hours (10 Watts).

My best guess for par values would be 100-150 par (30 watts) 30-50 par (10 watts).
