Hi Fish newb,
It's like riding a bike, really very simple, but tell that to someone whom has not rode yet! eh,
Light, C02, Nutrient's.
+/-1/2Tsp KN03 3x a week
+/-1/8Tsp KH2P04 3x a week
+/-10ml Trace 3x a week
@4wpg, you should be dosing at least
10ml Trace 3x a week
or you are going to have unpleasent issue's
gregwatson.com can fix you up with all the nutrient's
1lb of Plantex CSM+B
He also has the small measuring spoons, or you can get them at wal-mart.
Having an insufficient amount of plant's in a new tank is another error, waiting for them to grow in will invite algae, unless you cut your light by half.
I would reduce the lighting to 2wpg or less until you can give the plant's what they need for the highligh environment.
Some variable's involved when dosing, fishload, source water, etc.
Keep reading and asking all the questions you want, you will get it!
Read rex guide if you haven't yet, good place to start.
