What Fertilizers no I need?

You can dose dry or mixed with water directly into the sump.

I do not believe you need that chemical cocktail, unless you have some special water requirements. The 3 primary macros (NPK) and micros (Plantex) would be a good start.

I would recommend you read the stickies under Fertilizer section first, then read nilocg's WTS threads on TPT, and then contact him directly for specific advise and to get the ferts you need.

I agree with OVT. You certainly do not need everything in your list. I would also support Nilocg when you plan to make your purchase.

What you will need,

KNO3
KH2PO4
Plantex CSM +B
GH Booster if your GH is less than 3-4 dGh

Optionals,

I would also recommend adding the Iron chelate DTPA as well but it's not required. K2SO4 is nice to have on hand should you see signs of potassium deficiencies. It's so cheap you might as well throw it in just in case. The GH booster depends on the GH of your tap water. This is another thing that can't hurt to have. Adding GH booster won't hurt anything and in fact add some of the missing K. Here is a primer on nutrient management. It may make a lot more sense to you after reading this.

Thanks guys for the help and link. So am I better off, money wise to just dose dry? Or would I be better off to get Liquid NPK + M, already mixed? Seems to be dry would be best way as pre mixed would only last me 6 days.

You can create the same liquid solutions using your dry fertilizers if you prefer liquid dosing. Dry dosing is perfectly acceptable for a 180g tank though. So either way liquid dosing or dry the dry fertilizers are by far the most cost effective and versatile solution.

Thanks so much. My plan right now is to get everything for the setup ordered, and read a lot more before I start to plant, dose so on. I am in no rush to setup the tank, plus the stand/canopy won't be done for another month or so.

I figured I would start with about 3 lbs each, I assume that will last a while.

With a tank your sized dry ferts are definitely going to be the way to go. They wont be any better than liquid ferts just much more economical in the long run.
