water change problem!!

[escogs]

hello
when I change water %10, something is going out with water and make sps losing color to light. loosing color to light becomes every time for last 2 years. I tried many kind salt brands and got always same result. I am using reef crystal salt now.
when no water change everything is going good.

What kind of water are you using?? Tap water or ro/di water?

sounds like wuts going in and not wuts coming out. something getting in there with ur new water they dont like. perhaps time change your ro cartidges. do u have a tds meter?

Tap water might cause a variety of problems, but I'm otherwise short on ideas at this point. How often does the tank get a water change?

What are your alk/cal/mag levels and salinity of your new water compared to your tank water? Perhaps what you are putting in is so out of balance that you are shocking the corals with a spike of cal/alk or mag or all three...

what are you doing for nutrient export besides the water changes ( skimmer, carbon dosing,zeo etc.)


when you say losing color to light do you mean they are getting light in colors?

Well, your display is at 7.2kh and your putting in water that is 12kh..could be an alk spike

Hmm, I might try adding a DI phase, but I'm not sure that it'll help.
