| It's almost impossible to say, since each manufacturer that offers a plant bulb offers something slightly different. If you happen to have excess nutrients in your water but not enough light for algae to thrive, and if you upgrade to a bulb that emits more light in the red and blue ends of the spectrum than your current bulb, you could see an increase in algae. You also might not. Your fish likely won't care one way or the other what bulb you choose.
In general, plant bulbs are fine for plant growth, but often look worse to the human eye. |
