    I am trying to figure out how to make 2% Sodium Hydroxide solution to clean Flex tank. How many PPM? I am unable to find anything online.

    Why in the world would you want to use a caustic like sodium hydroxide to clean a flex tank? Something like PBW” (Powdered Brewery Wash”) or even Oxyclean should be quite sufficient.

    Mold in the tank and it’s what the manufacturer recommended

    20 grams of sodium hydroxide with water up to 1 liter would be a 2% solution. I believe the Flextank manual indicates using 2 or 3% caustic solution for cleaning. I agree with Mike above, I've been using the unscented Oxyclean with good results. Playing around with dry caustic is dangerous if you are unfamiliar with the material.

    I use StarSan in a garden sprayer (new) and dump out anything that puddles.

    An example of the superiority of the metric system: 20 grams in 1000 grams of water (i.e. 1 L of water which is also 1000 ml of water) =~ 2% by basic math. :)

    Spiritually, I agree with you. :b

    But, realistically, most people here discuss "gallons". ;)
