So I have only been into salt water aquariums for two years now but i still consider myself a beginner and i keep having a reoccurring problem that i need some help with. I have a 14 gallon biocube that has been set up for about 18 months now and i keep having out breaks of red slime. I have taken the bio-balls out I do 10% water changes every other week and i just cant get this under control. No matter what it keeps coming back, i have also put in another power head to help with circulation and nothing is working. Someone please help a fellow hoosier!!!
