EI based NPK + CSM+B Fertilizer for Aquarium Plants

The CSM+B is an NPK fertilizer part of the EI packaging.

The EI Method is an aquarium NPK based on the thought that excess nutrients will not harm anything in the tank. So even if you had a low light tank and were to dose 3x per week at the full amounts, as long as you kept up with the 50% weekly water changes it would not cause any problems.



EI Based NPK + CSM+B Fertilizer

This NPK fertilizer for aquarium plants is designed to be used with the EI (Estimative Index) dosing method.

The CSM B fertilizer package includes:

  • 2lb KNO3
  • 1/2lb KH2PO4
  • 1/2lb K2SO4
  • 1/2lb CSM+B

    Good packaging and fast shipping. Like how they come in specially sealed bags with names on all of them. Will buy more from here in the future. Only thing missing is some dosing instructions but you can find them online so no big worries.

    I needed some dry fertz and there was a well known vendor I usually go with, but shipping was outrageous. Shipping and price was great from nilocg. As soon as I placed the order, the order was being processed the very next day(sunday too). Will do more business in the future!

    Everything arrived as described. Just started dosing so we will see the effects soon. The only thing that would be nice if a little pamphlet was included with the package on how to dose or how to mix the dry ferts into solution. I know it’s on the website and all over the Internet, but it would be a nice little touch.

    I ordered this package about a month ago, since I’ve been dosing- my plants have taken off. I have to trim at least once a week. Order this product, you won’t be let down!
