ah I see..lol.. Doesn't really matter anyways until you want to fully empty them as they stay full all the time anyways.
Right now I have a 55Gal raised barrel per 1k light. You've got a TON of water capacity there. How long does that giant res last you per X amount of wattage.. before it needs topped up and re-nuted?
Do you just account for the leftover solution in that giant res + 25gal or so in your raised res?
I've been topping my tanks when they get to 15gal and filling them back to 55gal...mixing as per 40gal instead of 55... but I'm sure I'm not exact in my calculations and measurements..
