I can almost understand why I have blue green algae. According to their table,
What I don't understand is why one tank has normal (about 20, usually) nitrates and one is usually around zero or 5. Same exact water source. I do use different water conditioners though-stresscoat in the 20 and aquasafe in the 10. hmmmm
