I have had my aquarium up and running with no problems with red slime until recently my Dragon Goby died, which was my primary sand stirrer. Since then I have seen a big change in the amount of red slime algae over the sand. Is this outbreak due to a lack of sand stirring? I have done multiple 10% water changes since then and was able to pull out a majority of the carcass. I have tested the water and the parameters are normal. I also changed my lightbulbs about 9 months ago (they are due again-I just dont think that would cause such a difference.)
What do I do?
