I was wondering if you changed out to much water of your tank in 2 short a period of time would it cause the tank to start to cycle all over again. I've heard it would and it makes since but I didn't know if anyone can verify that this is true. Dave
Frequent Water Changes Bad?

Well the real worry about doing water changes too quickly is shocking the tank with improper salinity, calc, alk, and/or temp. If the new water is significantly different in any of those categories you can get some dieoff and a ammonia or other nutrient spike. The risk of such an occurrence on a new tank is very minimal however (especially if its just LR). If its a tank full of sensetive corals and other lief forms, then quick water changes are a last resort, but if its a young tank, there's no real problem with doing that

Veins are flowing with SW, now going back to FW!
No nitrate/ammonia should be present in RO water. When you do a water change with synthetic sea salt, some brands of salt actually contain the nitrate etc, so its not from your tap.
If you use a good quality synthetic salt, with RO water, there shouldnt be huge nitrate/ammonia readings anyway.
