Once my flourish runs out I plan on odering some watson fert. Does he have a fert that has pretty much everything I need in one mix? I have a high light tank but my plants are pretty easy growers, I have just been dosing flourish comp and iron once a week. My tank specs are 55gallon 260 watts cf, flourite with gravel and turface, i also have pressurized co2 and the tank is very heavily planted with easy stems and other forground plants. This setup works but I hate having to spend more money when I hear these dry ferts are so much cheaper. What would you suggest? Like I said I would like to get a mix that has it all in one, like csm+b?

I think he offers a mix bag which has all what you need in one mix

racialfish,
You're missing macro nutrients. How's the algae in your tank? Any signs of nutrient deficiency?

The typical purchase from Greg would be KNO3, KH2PO4 and CSM+B.

It is far better to dose Greg's dry fertilizers separately, so you can adjust the amounts of each if necessary. He does stock a PMDD mix, but that is short on phosphates and nitrates, so you would need to dose them separately anyway. Most of us, I think, just dose KNO3, KH2PO4 and a trace mix, either CSM+B or a commercial liquid trace mix, such as Flourish. It is better not to dose the phosphate and the iron at the same time - they form a cloudy precipitate in the water if dosed together. And, if premixed together, the iron will mostly be in the bottom of the bottle as a sludge.

I have little algae, my lights are on for 12hrs. So what would you all suggest I get? I was thinking a pound each of KNO3, KH2PO4 and CSM+B. Does that sound ok? And aobut how long will this last me?

Your order seems about right to me, and it should last you close to a year, perhaps longer. If you get two pounds of the KNO3 it would probably last you closer to two years.
