Stingray set-up

[PeteLockwood]

If there's ammonia in the source water, prime or ClorAm-X or Seachem Safe will make it safe for the fish and still let the filter deal with it. You can certainly set up a separate tank with a filter and make sure the ammonia's all gone before using the water for a change but it doesn't really sound like you have enough ammonia to worry about.

You may want to try taking some water from the tap, shaking it up a bit and leaving it for a few minutes, then test the pH again. Realistically, especially when keeping rays, it's Kh you should really be testing as it's Kh that will keep your pH from dropping quickly.

Yes, im using the APi test kits, I let the faucet run for about 2 mins before taking my tests. ill do it again tomorrow and see if anything has changed.

I test my water twice a week as i run a flow through system using ro, my water is as follows KH=3 GH=4 PH=6.5 NH3=0 NO2=0 NO3=less than 25ppm. I have to use coral gravel in my sump to buffer the PH because im using ro water. Hope this helps.
