I saw free FB marketplace aquarium supplies and there were so many great supplies including aqueon master testing kit, and surprisingly Root Medic macro and micro bottles!

So the website for rootmedic is no longer up and running so I’m just curious if anyone knows the specifics of these solutions.

Thanks all

bump:
The only thing I could find about this is a review on AC (is this link kosher now? It's been a few years since I've been on the forum)

My question is basically:
I got this stuff for free, is it worth keeping?

Otherwise I still have a giant jug of flourish that is at least.... 5 years old? Honestly i don't remember buying it/can't believe it made the cut with the move.

I feel like i've forgotten nearly everything about the hobby. :(

Hard to say anything about the fertilizers; it largely depends on how they were kept.

Macronutrients are generally just mineral salts, so they should be fine, provided they were stored properly. I would be more hesitant for the micronutrients.

For the testing kit, there usually is a 'best before' date that is printed on the bottles.

Interesting. If they ‘go bad’ what happens? The tank is sorted so I don’t necessarily need them.

For the micronutrients, the chelating agents will degrade with time, which will release whatever they are chelating (typically iron), rendering them essentially unusable by plants.


For the test kits, the test results might not be accurate. I have successfully used expired test kits, but I always check against known standards to ensure they are still reliable.
