I have a 4 cubes a day algae scrubber and it has one 23 cfl bulb on each side using big lowes reflectors and I'm getting lots of cyano on my screen every time I clean my scrubber it has green under it but within a day or two it gets full of cyano. The tank is been up and running for about a month and half and I only feed 3 cubes not 4 I have 13 fish and my tank is 150 gallons with a 40 breeder as a sump with an other 30 gallons of water.
Should I add higher wattage bulbs.
