I'm having some issues with my roller mat and ATO and was hoping for suggestions. My tank is a reefer 425 (112 gal total). I have a Red Sea roller mat 500 and a neptune apex with ATK. I'm noticing that my roller mat eventually turns, the water level inside the roller mat drops, resulting in my sump volume increasing. The volume is significant enough to raise my return chamber high enough to eventually trigger the high water alarm sensor on the ATK. I'm also wondering if this fluctuation is causing my salinity to eventually be unstable. My sump has a float valve built in, which I am using in place of the float valve on the ATK unit due to fit. I'm wondering if taking the low and high water sensors off of the base magnet and onto their own separate magnets with more distance between the two will result in less alarms? Any suggestions?
