I have my rays currently in a 280 gal. tank with a 100gal sump powering the filter. I agree with Zoodiver. I do water changes once every 2-3weeks. usually 100-150gals WC. I use Pothos plants to eat up my nitrates tho. after the 3rd month of doing this SAME routine religiously my test result were... ammonia - 0 nitrite - 0 and nitrates at 20-40ppm If every1 is worried about nitrates then throw some pothos plants in ur sump and watch as your nitrates drastically go down...
I am guilty of bashing an OP for what I and others on here would call and dumb post, but we really need to stop doing that, bc it will make them leave and not come back for help and keeps them from posting pics of their rays.
Heatha - depending on ur filtration system, and IF u use plants to help with the filtration i would say you might do a 30% WC once a week OR 40-50% WC every other week. From what i have learned on here, more water changes the better. cleaner water always helps your fish survive and thrive in captivity. It really depends on your setup when you need to do water changes.
I personally know a user on here that used to breed motoro rays in an 8x4 pond and did water changes once a month.... and they bred motoro 3-4times a year! sooo they were obviously doing right with their rays. depends on your filtering system and all that i think
