i plan to change to sand but i may be getting a different tank with overflows so i figured i would wait until then atleast so i dont make a bunch of extra work for myself. and my question is are these levels going to keep going down now that i did the water change? like i said they went from between 20-40 down to 10-20 checked this morning, so within hours it want down that far, ill check again tomorrow. SG 1.023 today. ammonia 0-.25, nitrite 0 pH 8.2-8.4 temp right around 80
