I have on my tank the lighting that came with the kit. More precisely the power-glo which is more for corals (i have a freshwater planted tank) and one which is yellowish which emits heat. I went to the pet store where it's cheaper and thought I was getting the flora-glo 2800k but she gave me the aqua-glo 18000k. Now I wanted to change the yellowish one for something with less heat. My question is, do I return the aqua-glo she gave me which is good for plants but not ideal, but is also fish color enhancing, or do i keep it as my front light and wait a little (few weeks) to combine it with the flora-glo? What do u guys use? Fyi, I want to change because even with litrite, nutriments and co2 my plants are turning brown! They are growing but the color itself isn't green it's somewhere between green and red
