RO/DI Tanks?

[robocop]

Is it wise to use RO/DI tanks? I ask because there would not be much water circulations in the tank if it was only used twice a month for aquarium water changes. Would this not lead to raised levels of Nitrite or ammonia?

If by tank, you mean the resivoir tank, no it won't lead to that. The water is essentially sterile with all organics and inorganics removed. It can theorhetically (SP?) sit forever without building up anything. The only problem is that the oxygen will be totally gone from the water and you must aerate it for it least 24-36 hours before adding salt to avoid causing problems with your tanks chem parameters.
