I ask because some test kits test for Nitrate's comming out of your RODI Unit. Have you changed out the DI Resin lately. As mentioned earlier water changes are your best course of action. Reduce your light cycle about a quarter of what you have now. If your lights are on 8-12 hours perday cut it down to about 6 and see how that works. Flow inside your tank is important aswell. make sure you can see watermovement down at the bottom aswell, that helps to control the detritus material that likes to settle in the dead spots of the tank. always rinse your mysis with rodi water before you feed your fish with them. Try reducing the feeding quantity. I wouldn't suggest not feeding or alternating days. Would you like to not eat for a day, or eat only every other day?? Just give what they can consume in 3-5 minutes.
