Do Dry Ferts go bad?

I was curious if dry ferts go bad mainly CSM+B.

I've had some of this stuff for years and never had any luck with it. I would always get a lot of hair algae when I used it, (dose based on EI dosage).

I just got new lights and wanna give it a try again, should I purchase new stuff or try the stuff I got now (its around 4 years old I'm guessing).

I started using flourish comp 5ml 3 times a week and it works for me but I'm getting close to running out again.

Tank size is 37 gallon. High light co2 etc.

Dry fertilizers are very cheap, and the amounts usually sold will last a long time in a typical aquarium, so if you have any doubts about the CSM+B you now have, just buy another batch and spread what you have over your yard, garden, planters, etc. An aquarium with high light will need fertilizing and CO2 if the plants are to grow in good health.

Okay, I need more Potassium Sulfate so I'll get some more.

Dry chemicals will not go bad. If they clump up just break the clumps up.
