You will need to read, read, read all you can from this forum. It pretty much contains all the answers you need you for the basics, in a variety of opinions too. Leading me to believe there is no single (right) way to do this. Most people here are experimenting and reporting their findings as to what works and what doesn’t. You need to decide what method will work for you and see how it goes. Me being a newby to this board have decided to use the "EI" or Estimated Index method. I feel its good for me as a beginner and helps me understand the relationship of the Macro and Micro nutrients with plants, algae, co2 and light. I looked on Tom Barr’s website and found this "EI" for your size tank. Its not a magic potion by any means but it does take some math and excessive testing out of the equation and gives you a place to begin.
10- 20 Gallon Aquariums
+/- 1/8 tsp KNO3 (N) 3x a week
+/- 1/32 tsp KH2PO4 (P) 3x a week
+/- 1/32 tsp K2SO4 (K) 3x a week
+/- 1/32 tsp (2ml) Trace Elements 3x a week
50% weekly water change
http://www.barrreport.com/

I've been using the EI method for 3 weeks and so for I've been successful at keeping the algae at bay and my plants are thriving.

Good luck

Sorry for replying late. Does this mean that I need those ferts, I should dose 3 times a week, but what does the +/- mean?

The +/- means the exact amounts aren't critical. I suggest you look at using Excel as a carbon source. It isn't very expensive for a ten gallon tank.

I suggest you order 1 lb of KNO3, 1 lb of KH2P04, and a 1lb of CSM +b. From what I have read and my limited first hand experience K2S04 is optional.

I and many others do not dose the K2S04. The KNO3 will usually provide all the K your plants need. It will not hurt a thing if you order it and dose it just in case.

The above quanties will last you years with a 10 gallon tank.

Thank You everyone that has replyed. What is a good base measurement for each? Ex. KNO3+ 1/2 tsp every three days.

I haven't answered because I don't know what the levels of any fertilizer are in my tank. I can tell you what I dose, but I don't worry about the actual level in the water, because I know I am dosing enough, and I do weekly 50% water changes to get rid of any really excessive dosage.

So, I should do say, 1 tsp every three days. Are there some that I have to do more, or less?

Read the second post - it tells you how much of each fertilizer to use and how often.

Well, I have been away for a long time, and have just ordered the ferts that rrguymon said plus I decided to get K2S04. But I don't know. How do you dose? Do you just dump it in, or mix it with water? please help.

You can dose the dry ferts right into the tank. Get your mini spoons out, scoop some up and toss it in. Dont dose the csm+b on the same days as your macros (kno3, k2so4, kh2po4). Good idea to read the "Dosing Regime's" Sticky note in this forum.

I just noticed that no one seems to have answered this. Did you find an answer yet? My answer is for you to begin dosing phosphates too. And, forget about the test kits for nitrate, phosphate, iron, etc. for now. Just dose using the EI method, and replace half of the tank water once a week. The brown algae is most likely diatom algae, which will go away on its own before too long, but if you get a few otocinclus catfish, they will eat it too.
