I have been searching for hours and haven't found an answer to my question.
I have a 2 month old 10g betta tank, (1 month fishless cycle, 1 month with fish), and so far my ammonia, nitrites, and nitrates are doing well -- too well.
I have not done a water change in 3 weeks, and my nitrate is still at 0.
The nitrate almost looks green in person..
I have one amazon sword - my only live plant. It was also like this before the plant was added.
Temp is 79-80 degrees Fahrenheit.
Recently, I have had a diatom spike on my driftwood for about 2 weeks without changes (I had one when I set up the tank, it went away but now it's back and relentless)
No big algae blooms besides little brown dots on my plant, I realize it looks like the dots are part of the plant but they are growing off of it -- looks like a form of algae, at first they were white.
The plant itself isn't doing so well but I'm picking up some flourish today to fix that (Someone at my aquarium store said flourish excel would work the same at providing nutrients, after some research clearly they were wrong)
My betta is fine, but they are non-stop glass surfing which is worrying (not flaring, just frantically moving back and forth on all sides of my tank)
What do you think the issue is, and how can I resolve it?
