Here's something that has always perplexed me:
Testing shows undetectable Nitrates and Phosphates, yet hair algae is growing out of control. People will often state that the reason for undetectable nutrients is that the algae is taking it all up; therefore, there is none left to show up on the tests.
Okay, that makes some sense, but...
Other people will state that they run with 20ppm or 30ppm or more of nitrates, yet they don't have any hair algae in their tanks. Similarly, others will state that they have detectable levels of phosphate but no HA. There are also those who have detectable levels of both but don't have HA.
What gives? How can both of these situations be true? An inquiring mind wants to know.
Thanks
