Raising Potassium?

Good luck. 
I would use potassium chloride. I'm not claiming that Cole Parmer is the best place to get it, just that it is possible. It isn't inexpensive. The different ones listed are different concentrations, but 4 M is the one to use for dosing as it is most concentrated.
This stuff is a lot cheaper, although I'm not certain of the purity.

I don't think it matters. The amount added should be small over time.
Hi Randy,
If I was to use this 4M concentration of the KCL as you mentioned can I use the Reef Calculator to figure out dossage strength? what would be the formula/multiplier? You probably want to know what test I'm using for my current K+..unfortunately I'm going for the big guestimate. I hope to bump up my K+ by 40ppm regardless of what it is at..theoretically this should be relatively safe, your thoughts?

From the sounds of it, almost everyone that is testing for K+ is finding thier levels to be quite low....Granted most of those folks are Zeo guys, and that may have something to do with it...though it may not! Given that my salt has ~320ish K+ to start and it should be ~380, its safe to say I am atleast 60ppm low, even if I am not depleteing any K+ which I think it has been shown that it does get depleted.....how fast is the question!
Given that KBalance doesnt indicate the concentration, its pretty hard to say for sure how much is being used. It would be nice to get a good reading based on using Potassium Choloride over time....

4 M KCl is 156,000 ppm potassium. So adding 1% of the tank volume would boost potassium by 156,000 x 0.01 = 1,560 ppm.

Yes, the 0.1 was a typo. The answer is unchanged.
You can use the calculator if you use my Recipe #1 for calcium (37,000 ppm) , and multiply the required volume by 0.24 to get the amount of 4 M KCl to use for a particular rise.

Hi Randy,
In your opinion how safe do you think that 4M HCL from Cole Parmer is to add to the reef?..if I was to use your calculator and add the dosage over let say a week?
BTW: You can order the HCL seperately for $24.37cdn, this includes 2-125ml bottles. The part number is 05992-48
thanks

WOW, according to the calculator it says for my 75g volume, it would require 276ml of that stuff to raise my level 150ppm....That is alot! Given that stuff cost $20 for 300ml.....
Perhaps I should try to buy that 8lb pail for $13???
Actually, I didn't see the triton in the Cole Parmer. In large doses that could be a concern.
