I personally Love apple cider soaked french fries. But that'd be a nice additive to a waterer for algae growth. Thanks for the idea. /img/smilies/smile.png
ETA: We always keep a gallon on hand. & I have a filled glass shaker with it. Ya never know when you'll need some for fries. /img/smilies/wink.png
Do like the British & sprinkle your fish & chips - or any fried fish - with a little ACV.
