Okay to start off I am new to fertilizing. All I presently do and what I have been doing for several years is putting the recommended dose from the product instructions, ex: In my 55 I dose 5.5ml Iron per week after my water change and also the recommended dose of the trace elements. I am using Seachem by the way. I do have C02 and I maintain this by drop checker. I have adequate lighting about 4 watts per gallon. Now my question is. I looked at the Seachem dosing chart and it says I should dose the amount of Iron that I usually do a week, daily, is this going to be okay? Also I have purchase Seachem's Nitrogen, Phosphate, and Potassium should I go ahead and follow the Seachem dosing chart in the Sticky? Any help would be greatly appreciated. My plants use to look a lot better in this tank and after reading a lot of the post, it seems like I may be lacking some of these other key ingredients. For ex: my Red Temple only grows with Red leaves on the top fourth of the plant and the rest of the bottom leaves turn black and fall off.
