I agree. I have the standard utility sink and it is a PITA to clean reactors. Great idea IMO.
BTW, when I remodel my tank room, I will increase the water stored to double. I want to keep 200g of RO/DI on hand. I like to age my water so every time I do a water change, I make new saltwater, but it would be a nice extra to have enough RO/DI that I could do a double water change if needed.
