I have a 90 gallon DT with a 40 sump / refugium. Using Red Sea salt, new tank (~ 2 months old), salinity 1.024, temp 78, ammonia 0, nitrite 0, nitrate 5-10. These parameters have been constant for three weeks since I changed my water (50%) after it cycled. I only have a clown, yellow watchman goby, pistol shrimp and cleaner shrimp. Do I need to perform a water change or can I hold off until nitrates rise to ~15ppm?
I run cheato in the fuge with the light on at night.
