TM AFR Shelf Life? Can I make a big batch?

[jayteerq]

Hi guys. I’ve been dosing AFR since the start of my tank now (6 months). Decided to buy the powder form to make my own as it’s cheaper. I have a 4 gal reservoir hanging around that I could put to use. I currently dose 15mL a day. I’m wondering if I make a big batch, will it still be good by the end of the 4 gallons? Do I have to occasionally stir it up? Thanks in advance!

TM just says it has a "Long Shelf Life." Intentionally vague. I would take that to say as long as you use it in a reasonable amount of time (months not years) you will be okay.

Whoops. I just did the math. 15,000mL is 4 gallons. At 15mL per day it’ll take me 1000 days to use up the reservoir :face-with-tears-of-joy:

I bought a 1000ml Nalgene water bottle to use as my AFR reservoir. The bottles have the ml marked on the side which makes mixing precise and simple. Buy two and use one for mixing and rig one up like this. Easy peasy
