I havent done a water change in about 2-3 months and my fish tanks is fine. Granted I havent tested for salinity, etc. But all I have been doing it is topping off the tank with RO water w/0 salt. Fish and coral are doing great. SHould I do a water change or just keep up with topping the tank off.

Havent changed water in 2 months

On my SPS tank I do W/C every other week at the least. On my sons nano is more like once a month. On my work tank since I hate bringing in water I do it only once every 4-6 months, and the tank is fine. I dont expect much from the work tank but to be presentable and grow some nice softies. The SPS tank needs more pristine water. So what your tank needs, is what you want out of it, and what your inhabitants require to do well. If its been two months and a correct W/C is easy to do why not?
all i have are some softies and two clowns, a royal gramma, and a wrasse. They all seem to be fine. I live in an apartment and it is a pain in the ass to do water changes and the salt I have is running low. I just got married so I havent had time yet this summer. I plan on doing a water change tommorrow but just wanted to check and see if I was crazy that things havent gone wrong. So how long can you go without changing the water?
might want to PM beaslbob, he tends to be a proponent of not changing the aquarium water, albeit, this is in his planted FW tanks... not sure if he does this in saltwater too. he has had success at least in his FW tanks.
that being said, if you're doing it out of a interest in that methodology of husbandry, that's one thing and more power to you, best wishes. HOWEVER, it sounds like this is more a factor of inconvenience and running low on salt, so I'd change it on a regular basis.
I'm sure you can go very long, as you have, without changing your water with appearant success... that's not saying it's a good thing. Kind of like driving 20k miles on an oil change, everything may seem fine, but in reality you're gumming up your engine in the process and one day you walk into the shop saying you have no idea why your engine seized up. Best practice for water changes is something to the effect of 20% monthly, or 10-15% biweekly, or 5-10% weekly... and I'll venture to say the biweekly schedule is probably most common out of the balance of convenience vs. stability.
good luck.
