My growth and plant health lately has been amazing, to me at least. Thanks everyone for hte help I do have a couple more questions though. I am now trying to figure out how to get the best color, or atleast more color, out of my Hydrophilia polysperma (sunset) and Rotala indica. Is it all in the iron, which I only dose in the form of plain old flourish of is it more to do wiht ratios of N and PI dose 1 ml of flourish every other day. Its my 10 gallon BTW ALso starting to devolope a bit of thread algae which I understand to not be a problem but a sign of good nutrient levels. WHat is the best way to get rid of it. Please don't say SAE. I can't get them locally. Will black mollies work. I would consider 1 or 2 of them. How big do they get?
