What is an acceptable amount of ph fluctuation for a typical day cycle? I am not currently having any specific issues just wondering and wanting to be proactive. Here is a chart from a few days for my tank.  I have a 90G tank with a 20G sump. I am running reverse daylight with Chaeto. I am dosing a 2-part daily, that's what the jump and then slight drop in ph is every morning. Lighting - 6 retrofit T-5's Current Water Parameters: Ammonia - 0 Nitrite - 0 Nitrate - 0 Phosphate - 0 Alk - 8.6 Calcium - 400 Magnesium - 1290 SG - 1.024 Temp - 78 |
