water changes

Hey I had a 75 set up with a retic ray last year. The tank was plumbed into a 70 gallon water storage tank and the water was heated and cirulated in it. I did a water change once a week. I took out about enough water to lower the level about 3 inches sometimes more from the top. Not sure how many gallon that was, but that might give you a good idea. Hope that helps.
There's no real concrete answer.
The reason bi-weekly changes of 20-30% each or weekly 50% are better is because you want your tank to be as close to your tap water chem as possable. This reduces the swings in PH/GH/alkalinity from water changes which are very stressfull and can be deadly.
That being said, if your nitrates stay below 20-30ppm, and you have a good enough buffer to prevent a PH crash, you could go a month or more without waterchanges. Is that best for the fish? Probably not.
To be safe, I'd say do 40% a week. Testing once or twice over a week (do this for atleast 2 months) your PH, KH, GH and Nitrates, if they are acceptable (unchanging for the first 3, and nitrates below 20-30ppm,) you should be fine.
Just my 2 cents.

That stingray is going to need a bigger tank. I would also add some purigen to the filters to keep the baddies out of the water. 1-2 water changes per week should do the trick.
you'll get 10 diffrent answers for this question.
depending on your filtration the size of the ray and your feeding habits your water changes will have to be done according to the water paramiters.
get a good test kit an check every day .
understanding what the readings mean will be good for you and your ray.
