I recently placed an order from bobstropical for CSM+B and Potassium Sulfate, but it appears that they ran out of the potassium sulfate, and shipped the CSM+B, I really wish they would have just canceled both, because now I am going to have to pay twice the shipping.

So my question is, is there a common product that is pure potassium sulfate like there is for so many of the other fertilizers?

Thanks for any help
 
Honestly, Bobstropical should pay for the shipping because as long as the website says in stock, they should honor that and not have you pay extra.
 
You know to be honest, I may have jumped the gun. They refunded $3 but didnt say what it was for. I was thinking the potassium sulfate was $3 so I just assumed that they refunded the money because they were out of stock, but now looking at it, the potassium sulfate is $2.50. So maybe they over charged for shipping and the $3 was a refund for that, I guess I will just wait and see. Apologies to Bobstropical if that is the case.

Anyways, is there a common product that is pure potassium sulfate?

I don't know of any commercial product that is specifically K2SO4 but if you are trying to target potassium then try No-Salt/Nu-Salt which is KCl. Fleet Enema is KH2PO4 if you're not worried about dosing phosphate. There is also a lot of products that are KNO3 if you need nitrate as well.

So I can substitue k2so4 with nusalt? Its the potassium that is important and not the sulfate? I am planning on doing the DIY root tabs and then dosing the water column as well with what is left over? I am pretty sure that I want to avoid adding phosphates because of the increased risk of algae, right?
 
Yes, KH2SO4 is added to target the potassium (K). Sulfur is also needed in smaller amounts too but not something people generally test for or add specifically, at least to my knowledge.

Some people will blame any amount of phosphate for algae but it's simply not always the case as it's actually a macro-nutrient that plants NEED to survive (well, phosphorus in its elemental form technically is, but is normally introduced into aquariums in the form of phosphate). Whether you should dose or not will depend on what is in your water supply and what you are trying to accomplish with your plants. But never try to strip the water completely of any phosphorus in a planted tank.
