Hiya,
Yeap, I've got a 37 gallon with 25lbs of LR and 40lbs of BR that has been up for 3 months. It's starting to turn purple, pink and green. I've also seen pods and flat worms
Hiya,
Pods are a good thing...they mean you're system is healthy.
Flatworms...can be bad if uncontrolled. They can multiply very quickly until they reach plague like proportions.
