I need a straight answer on this please someone!
I am having trouble figuring out Potassium.
According to a website I bought the following products to feed my plants Potassium
Plantex CSM + B
So can someone tell me, when someone says K
, which potassium are they referring to?!
For instance, one forum says that he makes sure that he has 30ppm of Potassium per week
Nitrate (NO3) 20ppm per week.
Potassium (K) 30ppm per week.
Phosphate (PO4) 3ppm per week
Magnesium (Mg) 10ppm per week
Iron (Fe) 0.5ppm per week
Ok thats fine but which Potassium?! This is confuding the hell out of me no matter how much I read and I am sure my tank is suffering for it!
My levels must be all over the place so I started testing again. Check this out....
My phosphate is through the roof at 5 to 10 ppm. So i stopped dosing Mono Potassium Phosphate
(KH2PO4)...is this the correct one to stop dosing to bring that down?
My Nitrate was through the roof so I stopped dosing Potassium Nitrate
(KNO3)....is this the correct one to stop dosing to bring that down?
I have no idea about my Pottasium Sulphate
(K2SO4) level because i couldnt find a potassium test that was for sulphate until someone pointed one out on here which is like £30 which i cant afford at the minute.
The only one I feel comfortable with is CSM + B because that is easy and they all have different names! So confused even after nearly 2 years...please help a frustrated fishy man out!
P.S I have just seen this.....
"Potassium is an important macronutrient, and it is commonly in short supply in an aquarium. The amount of potassium from food and waste is often much less than the amounts of nitrogen or phosphorus. So adding potassium is often a good idea."
But isnt adding Nitrate adding Potassium because it is Potassium Nitrate??! I am so confused!
