Storing liquid PPS Pro Fertilizers

I mixed my first two 500 ML bottles last night of macro and micro. I have just a 45g so it will be a long time before I need to mix more. In the mean time, where do you store the liquid? Frig? Under aquarium?

The micronutrient mix tends to grow fungus, sometimes even despite the addition of a few drops of hydrochloric acid or glutaraldehyde. It is best kept in the fridge, wrapped in foil.

The macronutrient mix can be stored at room temperature or at 4C.

Hmmm. Hydrocloric acid. Sounds bad. Is this something that is readily available anywhere? If it does develop fungus, does it have to be thrown out?

It generally is available at the hardware store, sold as tile cleaner.

Alternatively, you can use a few drops of Excel to achieve the same effect.

I usually remake when I see fungus growing, though some people will filter and continue using it.
