I have ordered a replacement 75 gallon tank and was wanting to try making it a planted one. I was wanting to try a freshwater low tech/low light because this will be my first attempt. The tank will come with a 120 watt cover (roughly 1.5 watts per gallon). For the filter system I will have an Emperor 400 and a under gravel filter. I have gravel from a previous tank already so I was going to use that. My question is will this set up work for low light plants? Do I need fertilizers? I have done a great deal of reading on these boards and it seems there are differing opinions on some of the things I listed above. Any help you could give a newbie would be greatly appreciated.
