My tank is 8 months mature and out of the blue I get a diatom outbreak on the sand. All water params are great. I removed a yellow filter sponge that I left in too long in my wet/dry and replaced it with a new one. I do RO/DI h2o changes weekly. Any thoughts? So far I've just rode it out. Almost like my tank did a little mini-cycle.
