Reminds me of when I debug why my aquascape (I’m a beginner) keeps having algae outbreak such as GSA and Cyanobacteria.

I have a lot of things correct, CO2, light, photoperiod. LLM told me that I have too much kH and gH and too much phosphate.

Followed the LLM advice, didn’t work. Apparently its an outdated advice. My kH and gH is high (not using RoDi water, just NJ tap water) but not that high such that plants struggle to get CO2, and my level of phosphate doesn’t necessarily what made the algae bloom.

Turns out my nutrition was the culprit. I bottomed out on Nitrogen all the time. But when I told that my Nitrate is 0 the LLM didn’t say a thing and instead “you got everything correct”.

Digital bullshit.
