No algae at all—problem?

TEX · May 2, 2020

I can’t believe I’m asking this, but...

My 10 gallon has been cycled for about 2 weeks, added first fish a week ago, fed frozen daily, only filtration is filter floss and matrix bio media.

I’ve ran lights on a full schedule from day one of cycling, and the tank is near a window, so plenty of light.

Despite this, I’ve seen exactly zero algae in the tank. Fish is doing great, water is clear, no signs of anything wrong in the tank. Nitrates are around 25.

Is it strange I’ve seen no algae growth? Obviously, I’m grateful for no algae issues thus far, but is it a sign of anything wrong too? I just want to be sure. I mean, even established tanks get some algae growth on glass at least.

I would expect some to show up any day now, perhaps preceded by some perfectly normal rusty colored diatoms on the sand.
