Hey all I am at the end of my rope...not really, but I am getting fed up with the tank. I have been trying to get a planted 55 going. I have a high tech set-up. I use pressurized co2 with a GLA diffuser, zoo med 2x52W t5 ho light fixture and i have been using the GLA PPS pro fertilizer setup. I have experimented with differing lighting regimens, but my plants are yet to pearling, nor is there any real growth going on. Most of what I end up with is BGA. Am I using the wrong fertilizers? most of all how long should the lights stay on? Is my lighting too weak? I appreciate the input.
