I know you keep bringing up that point a lot, but 30 minutes isn't very far, and it's a trip you'll have to be willing to make if you want your tank to be successful. I bring Home Depot buckets to my LFS every week for RO/DI and can fit them in my trunk - I don't know how much space you have in your car, but in my Honda Civic I can fit 6 5-gallon buckets of water.Im not trying to ignore . My LFS is 30 min away. And I cannot exactly bring 50 gallons of premixed water in the car. Im upstairs. The hose would be downstairs and outside. It just doesnt work.
