Are there any cons to having one with a storage tank?
I know ro water tastes terrible after a day or two of sitting - but would it matter to the fish? It is in a sealed water tank that comes with the ro/di unit.



Already have one - but ours has a small 5g heated tank to use while the machine gets up to speed. So hot water isn't exactly the best in my case anyways.

Any way to bypass the 5 gal heated tank with respect to your RO/DI? The water only needs to be warm and the flow through the RO is slow enough that you shouldn't need a temp boost from the 5g heater. Generally making pure water is a long process, depending on your membrane rating. Could be a real time saver if you can run some warmer water to the RO input. Oh yes, water pressure also has a significant impact on production rates. If you're on a well or something, you might even need a booster pump. Ooops, that's more cash again...

BTW, how do you like the tankless heater? I assume it's natural gas?
