water changing

Hello all,



I have a 37 gallon reef tank with around 16 corals, half sps, half lps. I was using tap water which read near 79 TDS. I just recently changed over to rodi about 2 months ago. I was wondering if I would be setting myself up for success by doing a 10 gallon water change every week or is that too much? Also evertime I get a new frag of sps the color tends to dull or amost go white. parameters are:



Nitrate: 0

Ammonia: 0

phosphate: 0

calcium:420

dkh: 8



lighting: evergrow D120 led fixture.



Also is there anything I need to supplement? I use instant ocean reef crystals in the weekly 10 gallon water change.
