Cutting lighting won't help, as the plants need 6-8 hours a day. Test for NPK and let us know the levels. Generally with low light plants, algae grows in that quantity due to a lack of one or more nutrients, not excess light.kmill;4876084;4876084 said:All plants are attached to driftwood, I have not used any root tabs. Substrata is estees permacolor quartz sand. Maybe the scrubber is getting all the nutrients not sure. A SAE would be lunch in this tank. Should I cut down lighting or stage it differently?
