Ok so I already had one really bad case of Diatom Outbreak where my rock turned dark brown. I got Phos-Guard and Carbon and mixed it and put it in my filter. I also got Sera Marin Silicate Clear and added that to my filter. Within a day my rocks were completely clear. 3 days later and I started getting a yellowish/brown version of diatom I am guessing on my sand bed and all over the glass. Not so much on the rocks. The last few days I have been brushing the dust off the glass and mixing up the sand, but it keeps coming back. Do any of you have more advice on how to control this? Should I use less light for a couple days?
