Nitrate is Between 10-20ppm…. Everything else us at 0ppm. Is this the reason I have algae on my glass?
No, that is low nitrate reading. Algae is from inconsistency in lighting and an imbalance of plants and nutrients. More flow reduces algae and twice weekly scraping and wiping helps the most.
Lights on for to long is a good bet have you tested for phosphate?
That algae just might be the reason your nitrates are as low as they are.
