Easiest non-green plant I know of is Crypt Wendtii and maybe red root floaters... Ludwigea Repens is also easy if you have enough light.
I use seacham root tabs. And I just looked around on there website, the package itself doesn't say anything about potassium. But after reading through some questions sent in to seacham I came across a seacham tech saying this:
"Both the Flourish and Flourish Tabs do contain potassium in the form of soluble potash. Potash is the common name for various mined and manufactured salts that contain potassium in water-soluble form. However, keep in mind that in some cases you may need to add in an additional potassium supplement, depending on the utilization ratios in your tank."
If need be I do have some dry ferts, KNO3 and KH2PO4. I would like to stay away from using these as I don't have enough knowledge to make sure I'm using the correct amount to not mess my tank up.
