This describes Sanjay. That man can grow SPS like nobody's business! It doesn't matter which light he uses he grows colonies out of frags in months, and color to die for. Unicorn poop I say.

Holy crap! Most people use nitrate dosing to achieve trace amounts of nitrate or maybe up to 5 ppm, not 25 ppm! Why did you go so high? How long did you elevate it for? I dose Sodium nitrate to achieve 0.2-0.5 ppm nitrate.
