Should I Fert?
I have a low tech 55 gallon planted tank with low light, dirt substrate, good water filtration and water movement. I want to do something to spark new plant growth, but want to keep in low tech in that it is rather undemanding. I do a water change once every month or two. I have Flourish "comprehensive supplement for planted tank," and Flurish Excel. Should i use these as directed? Or will it that require me to do a bunch of other things?
