HelplessNewbie Posted June 23, 2023 Share Posted June 23, 2023 (edited) I have noticed that water gets cloudy when my sponge filter has been off for many hours. Is there a monitor for water clarity, or a way to verify that my filters are in actual operation? We have them on smart switches but what if airline tubing somehow popped off?

nabokovfan87 Posted June 23, 2023 Share Posted June 23, 2023 you can use something external to the glass on a microcontroller (arduino type of thing) on the glass. They have stuff that is based on infrared or laser based sensors. It's a common type of sensor used for things from measurement all the way up to alarms. You could also look into a flow sensor on the uplift tube.... think, watercooling parts for a PC. Off the shelf, something for water monitoring though, I'm not sure. Maybe conductivity? 1 Link to comment Share on other sites More sharing options...
AndEEss Posted June 23, 2023 Share Posted June 23, 2023 There are TDS meters for things like a Neptune Apex system that you could employ. But a $500+ system on a tank with a sponge filter might not be the best option. 1 Link to comment Share on other sites More sharing options...
