I tested my nitrates and they are at 40 ppm. Nitrites and ammonia are undetectable or at least don't result in color changes on my kits. I will probably do a PWC tonight. I can't help but think that plants would help with the nitrates. What are good plants for a beginner? I have a UGF so it may be a problem. I let the light stay on about 12 - 14 hours a day. I see some small containers that hold plant roots. Would they help? I've got YoYo loaches, clown loaches, black ruby barbs and blue rams. I'd like some low maintenance, good looking, plants that are both floating/suspended and anchored.
