Hey everyone! I have a tiny bit of red slime in my 20g. Can I get some causes/effects/benefits/negatives/solutions? Thanks!

It happens, pretty natural process. It can happen in a low nutrient system just like a high nutrient system. I have it growing in my skimmer and sand bed from time to time. I think its due to dosing amino acids since my nutrients are near undetectable. Good flow, wet skinming, not overfeeding, all help reduce cyano,
How old is your tank?
Its probably a good sign that your tank is maturing.. However, if its getting worst then you need to evaluate your source water and nutrient export.
