You can get a pottasium test kit made by aqualight, it is the same test kit made as zeovit, however the aqualight is cheaper.

Why not just use some buffer for K+ additions like potassium bicarbonate or potassium carbonate, if one feels a need to add K+ ?
Where would folks obtain that cheaply?
If you need a big boost in K+, that would boost alkalinity quite a bit.

Two questions...
The Seachem Flourish Potassium product is potassium sulfate, right? Could anyone explain what happens to the sulfate part of the equation when dosing this? Any way to calculate the products effect on potassium so we could estimate dosage?
What provides the potassium in saltmixes? Wouldnt that same chemical be a safe way to raise K+?

Sulfate is the third most abundant ion in seawater by weight, at 2710 ppm, so small boosts to it are likely to go unnoticed. I discuss it here with respect to magnesium sulfate dosing:

Yes. My DIY salt mix uses potassium bromide and potassium chloride:

An Artificial Seawater Recipe
--------------------------------------------------------------------------------
For those who are interested, the following artificial seawater recipe is taken from "Chemical Oceanography" by Frank Millero. It makes a recipe that matches 35 ppt seawater in terms of major ions, but does not try to match all minor and trace elements, most of which will be present as impurities in the major elements.
23.98 g sodium chloride
5.029 g magnesium chloride
4.01 g sodium sulfate
1.14 g calcium chloride
0.699 g potassium chloride
0.172 g sodium bicarbonate
0.100 g potassium bromide
0.0254 g boric acid
0.0143 g strontium chloride
0.0029 g sodium fluoride
Water to 1 kg total weight.

Those are usually potassium chloride.
I'm using this KCL for my tank.

OK. I feel really stupid for buying liquid potassium supplements now. A fool and his money I suppose. 
I found a bottle of 8oz. potassium chloride powder for <$3 at amazon.com in the health section (link). That's about 118g of KCl. The website for this product says "100% pure and free of filler". Greg Hiller posted that 7.3g of KCl would raise K by 10ppm in 100G of seawater, so this 8oz would be enough to raise 100G by about 160ppm.
Many people also mention KCl pellets for water softeners would work, but I'm not sure how pure those are.
I'm thinking of trying the KCl powder to raise K to NSW levels when I mix new saltwater, along with my usual alk/Ca/Mg corrections.

Bebo,
I will mix it with SC salt then measure all the parameters before I dump it into my tank.
It's a waste of money for me by dosing two of 500ml Potassium bottles to raise my tank from 220ppm to 330ppm. My net vulume system is 180g. I'll keep you update.

yeah keep this thread updated, my system volume is 300 gallons i went through a large bottle of the Zeo K+ and my level only went up 25-50 points.. there goes $75 for nothing. i would love to use the stuff posted above if it works and does not cause any problems...

i started at 1ml a day for my 75 gallon reef... i moved it up to 2ml a day with no ill effects colors are def. deeper and nicer... im also dosing tropic marine A and K elements and notice a big difference from what i use to have.... im dosing low on the potassium jus to play it safe cause i dont have a test kit for it... and i do agree with u shouldnt dose on what u dont test but im doing things my own way
