I have a 75g Central/South American tank, And I recently changed the lamp from the original one that came with the setup (Tropic sun 32WT8 5500K) To a All Glass Aquarium 32W T8 8000K Spectrum lamp. This is just a single 48in lamp. So when I switched it was like night and day, Very Crystal clear looked perfect. Then about 4 days later tank started to get greenish Cloudy. Been this way for 2 weeks now.... I keep it clean, routine water changes and gravel cleaning. Filtration is a Rena Xp3 , Marineland 350 and a Penguin Power Head 1140.. Everything looks good on the test strips.... Im just tired of the green. Any help would be great. Thanks
