I have been getting more and more into planted tanks as of late. I have quite a few of plants in the tank and a decently stocked 20 gallon. With DIY CO2, and a Hagen ladder (1 Hagen bottle and 1 2 liter bottle), is two t5 ho 24 watt glo lights on the tank. I am trying out a low level EI dosing regime. Do I have currently have to much light? Growth is ok, the dwarf saggs are going crazy, the scarlet temple is only doing so so, and crypts not so well. No algea problems as of yet, doing a 50% water change weekly. Stem plants doing ok, I guess. I have been reading more and more and I am wondering if 1 T5 HO is enough light, and is 2 way to much light for the tank with just DIY? Please help me out. Thanks guys. This stuff is fun.
