Hello,
I have a 3-month-old Fluval flex sea 32.5. Everything was going well, parameter, per API test kit, were all 0ppm (ammonia, nitrate, nitrite). However this last 2 weeks I noticed a growth on my back wall that I have not seen before, and could not find similar images here on this thread. Hopefully, someone can help me identify this "thing". Images of my tank are below:
