Ok guys I have a small problem. I tested my tank this evening and everything came out fine except the nitrates rose to about .20ppm I know this is still not really that high but I think this might be the reason for getting a small outbreak of hair algae. I just placed an order to strengthen my cuc to get rid of the algae, but I'm still a little bit worried about the nitrate levels, when the clean up crew starts to take out the algae will the nitrate go down?
