No-I am not dosing syrup as a carbon source. I have a large reef tank, but my kids own a shave ice trailer and a lemonade stand. We mix our own syrup using sugar and I thought it would be very similar to a saltwater mixing station so I figured there would be a lot of input from all of you. Currently we mix 5 gallons at a time using a 25lb bag of sugar. I would like to mix around 50 gallons at a time, then use it to fill smaller jugs. I wasn't sure if I could just buy a tank and throw a big powerhead in it or if I should use an external pump. I don't need it to constantly stir the syrup after its mixed. The syrup is still very fluid (not thick like pancake syrup). What kind of setup would you recommend? Any ideas?
