Guys, I currently use seachem fertilizers for my plants but thanks to a friend, now I know that Greg Watson is much, much cheaper.

So I'm getting ready to make an order and I need to know what is what and what I should be buying:

Iron Chelate-Is this Iron?
PMDD Pre Mix-Is this Flourish Comprehensive?
CSM+B Plantex-No idea what this is, anyone?
Mono Potasium Phosphate=This has to be phosphate right?
Barr GH Booster=What?
Calcium Sulfate= :confused:
Calcium Chloride= :confused:
Potasium Sulfate=Is this potasium
Potasium Nitrate=Is this Nitrogen
Calcium Nitrate= :confused:
Calcium Calbonate=Is this Carbon, Excel?
Magnesium Sulfate=:confused:

If anyone can answer feel free please.

I also saw that they don't have instruction on how to mix the ferts with water. Any help would be greatly appreciated.

Just read the stickies on the fertilizer forum page, and you will know all that the rest of us know. If you want simple and easy, concentrate on the EI (estimative index) sticky.
Greg, I like doing the dry ferts. I just did a significant water change (5gallons out of 27 Gallon tank) and tried to make sure that I got as much of the carbon out of my filter pads. The DIY 3 Liter Soda Bottle CO2 is doing its thing very well.

My question is about my water and the dry ferts. I don't really know what green water is, but my water is starting to get 'cloudy'.

Is this caused by too much dry ferts? (The water in my 10 Gallon where I use the same dry ferts is crystal clear.)

Hoppy, I am still using the light schedule that we talked about last. Should increase or decrease the light? (sorry if I posted these questions in the wrong place).
"Cloudy" water can be many things, from bacteria, to algae, to CO2 bubbles, to fine dust from the substrate, etc. Adding fertilizers is barely a possible cause - if you add phosphate and iron together they chemically combine and make a haze. The best suggestion I have seen is to put a sample of the water in a white bowl - if it looks green it is green water, if not, it isn't. When I dose my CSM+B+extra iron dry, as I now do, I often get a white haze for a few minutes, I assume from the phosphate already in the water from the day before.
