Potassium Dosage Amount

[Adamantium]

I'm using Potassion-P powder by Brightwell to take my potassium from ~340 to 400. The math I did adds up to a dosage of 205ml/day of the “advanced” solution. That seems like a lot for a 40B to handle day in and day out.

I could have my uptake, and/or math wrong. I've only been checking for a few days now, and I only have a few SPS colonies, nothing crazy.

For those of you who test and dose potassium, what does your daily uptake look like?

Thanks, all!

Here are the Basic and Advanced instructions:

Basic
Dissolve 2 grams (~½ teaspoon) of product per 20 US-gallons of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed to maintain the potassium concentration within a range of 390 - 410 ppm. When used in this fashion, 1,200 g treats up to 12,000 US-gallons (45,425 L).


Advanced
Create a stock solution by dissolving 5 grams (~2 teaspoons) of Potassion-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase the potassium concentration (“[K+]”) in 1 US-gallon (3.785 L) of water by 1.7 ppm. [Reference: Each g of Potassion-P will increase the [K+] in 1 US-gallon (3.785 L) of water by ~129 ppm.] If initial [K+] in the aquarium is below 399 ppm, add stock sol’n at maximum rate of 10 ml per 20 US-gallons daily until desired concentration is attained, then dose daily or weekly as needed (see below). Maintain [K+] within a range of +/-10 ppm. Once desired [K+] has been acquired, measure aquarium's [K+] at the same time each day over a one- to two-week period to determine the daily rate of potassium uptake (i.e. the decrease in potassium). To determine daily dosing rate (preferable to weekly dosing): estimate volume of water in entire aquarium system (US-gal.); divide the daily decrease in [K+] by 1.7; multiply this number by volume of water in system to obtain daily ml of stock sol’n required to maintain stable [K+].

Daily uptake? May tank never depleted potassium.

There's no reason tanks need to have deplrtion (or accumulation). If it does, it indicates an imbalance between foods and tissue growth. That will, of course, depend on the foods used.

Thanks for the reply! So basically, to up my potassium, you'd suggest feeding higher potassium food?

Or, can I just use this supplement to get up to 400PPM and then stop dosing, more or less?

Forgive my ignorance. Even the packaging (which I realize can be misleading) suggest you calculate "daily" consumption.

I'd correct it by dosing.

Appreciate it, Mr. Holmes-Farley!

So, to be sure, you’re suggesting bumping it up through dosing, but then stopping and letting it just sit at 400? Maybe dose a little after a water change, but otherwise it’s not a daily dose?

Also, is it normal for the required dosage to be rather large? It suggests I add no more than 20ml to my 40 gallon per day, but I did 50ml the last two days and saw almost no change in the potassium level.

Yes, dose it up to 400 ppm, then watch it once a week or two and see if it changes, and if so, redose.

It is normal for any material needed 80 ppm to be a substantial dose.

What product are you dosing?

Thanks so much. It’s Potassion-P powder by brightwell.

Pros go to 800-1200 for best color for pictures for corals to sell them to you and then you wonder why them corals lose color...lol

I've heard that some folks experiment with substantially raised potassium, but I didn't know anyone went to 1000+ ppm.

If its done only for photos, that's a serious breach of trust, IMO, and I'd never buy from them.

Theres no difference between that and color filters used to sell corals about same pictures out there even on here in community , its how it is now.

This is true what is a deep fake and what is real now a days.

I made a stock solution of Brightwell Potassion-P and RO water but it created a lot of residue. I used 147g of powder + 474 ml of RO water (I wanted to get as close as possible to 500ml total and at least a solution with potency of 1ml raises 0.5ppm K in 50 gallons).

Perhaps I should have started out with heated RO water, but I only heated it after I already had the residue.

I wonder what is the residue and if my solution is still going to be approx. to what I attempted (1ml raises 0.5ppm K in 50 gallons).

Your feedback is appreciated.

You made it too concentrated. Try using 2-10x as much water.

Thanks for your reply. Is the one that I made ruined?

 

[Randy Holmes-Farley Verified Community Expert]

No, just add more water and see if it goes clear. If it doesn’t, it is just an insoluble impurity that you likely do not want anyway, and I’d let it settle out and use the clear liquid.

In the future, I’d recommend food grade potassium chloride from brand like iherb. Very inexpensive with a purity assurance that Brightwell does not provide.

Randy, thanks for the guidance. Noticed that the Brightwell product has 2 types of Potassium compounds in it. I thought that both were needed, and furthermore, in the specific ratio.

What I deduct then is that Potassium Chloride only is OK.

Why would Brightwell include the Potassium Sulfide in their product?

Probably to keep it from oxidizing to iodate, but iodate is the main form in seawater so I would not worry about not having it.

Brightwell is not a paragon of chemical enlightenment, with some serious errors in their products.

Thanks Randy!
