Potassium Mixture

[mginster]

Sanity check before I buy an additive.

I am looking to purchase this:

NOW Foods, Potassium Chloride Powder, 8 oz (227 g)

www.iherb.com

Calulator:

James' Planted Tank - Dosing Calculator

www.theplantedtank.co.uk

Tank volume: 120g

If I dump the entire 227g bottle into 1000ml of water it will give me a strength of +.19ppm / 1ml. This means 362ml to raise my tank the needed 70ppm.

@Randy Holmes-Farley In another thread you recommended to only use 74% of the suggestion from the planted tank calculator. What was the reason for this? I assume salt vs fresh. However, in other calculations I did with Potassion and the moonshiners calculator it seemed close to the same strength with no reduction. IE I found 100g/1000ml was +.09ppt/1ml with NOW and +.1ppt/1ml with Potassion, yet moonshiners recommended a full dose like planted tank calculates.

Other Potassium dosing questions:
- How fast can you raise potassium? I need to move 70ppm.
- I saw other dosing instructions around the web stating to not dose any other additives while doing potassium (I do Trace A and K / Alk / CA / Balling C daily)
- Does chaeto consume potassium? I grow a ton of it and trying to see why I am so low.
- Does anyone get significant algae growth when spiking it this much?

The ingredients list Magnesium carbonate, so I would look for something that doesnt contain anything other than Potassium chloride. Lots of options.

That was one that Randy recommended from another thread. He did mention the mag carbonate shouldn’t be a concern I believe.

I think it is fine. A correction factor is needed because none of those entries are potassium from potassium chloride. Potassium chloride has a different percentage potassium than those other chemicals listed (e.g., potassium sulfate) Which entry did you plan to use?

All organisms take up potassium and all foods contain it. Hence it does not necessarily deplete.

There’s no reason to alter other dosing when using it.

I’d boost is 20 ppm per day.

I’ve never heard of it boosting algae.

Ah yes that makes sense, I choose Potassium - from Potassium Nitrate in the calculator (I believe that is what you suggested in another thread for the 75% mentioned)

Thank you!

Side question, is the NOW one good to utilize or is there better?

Magnesium carbonate traces are no concern.

Yes, 0.74 factor is good for that choice.
