I have a 15 gallon planted aquarium that has recently developed a serious algae problem. I am seeing a ton of dark green, long strands of algae growing on my ludwiga and baby tears. I have nerite snails and ghost shrimp, so a chemical algaecide is out of the question. I also recently purchased a filter with a UV
sterilizer and I am not sure it is helping much. Circulation in the tank seems pretty good, and I am pretty good about water changes. Any suggestions and advice would be greatly appreciated.
