Cheap and effective LED modification
I have a Fluval edge 12G for about 3 years. After my second set of the original LED fixture died, I recently decided to improvise. I bought new 3 X 19 inch submersible LED light bars on Ebay (for a total of 31$ including shipment). Each bar has 57 high output LEDs (no par data available…). I fix them together with an electric insolation tape. You can control the angle of the light bars so all the tank gets light. You can also buy the shorter version and install them inside the tank (submersible!!). I tried that, but had a problem of algae growing on the bars. So far my plants are growing nicely (so is my BBA).
