Stump remover causing excess Potassium levels?

[Reeferz123]

I have been dosing Stump Remover for the last 2 months to raise nitrate levels from 0 to 5-10. I recently got back my ICP test results back and showed the following:

1. High reading of Potassium 493 mg/l vs 400 mg/l. µg
2. Lithium was detected 254 µg/l vs 200 µg/l
3. Molybdenum levels were high 26 µg/l vs 12 µg/l

Should I look into switching to pure reagent grade?

I dose the following in my system (mixed reef):

1. Stump Remover
2. Seachem Flourish Phosphorus - to keep phosphate levels between .02-.05
3. Acro Power

I am not sure if Acro Power can be the culprit but I am almost considering to stop dosing this as I have not seen any difference.

Any feedback is appreciated.

You should switch to the product I recommend and avoid potassium altogether: food grade or analytical reagent grade sodium nitrate.

Amazon and Etsy have multiple brands.

Ok perfect I’ll order sodium nitrate ratio to mix is same as potassium?

It takes a little less since sodium weighs less than potassium. Above 84% of the amount of the potassium salt.
