Review on ROOYLE Backlight PPM Measurement Temperature Aquariums: Advanced Aquatic Monitoring Solution by Travis Caminiti

This review is for the TDS meter only, I did not receive the pH meter. My use case for this is to monitor the TDS level in my water filter and fabric softener that I use to wash cars. The water is pretty hard where I live and I absolutely hate water stains on the paint! I have a system that filters and softens the water. Softener cartridges need to be regenerated after the media is filled with removable solids. After several regenerations, their service life has expired and the carrier must be replaced. Color, an obvious sign that the media is no longer working. It wasn't ideal as I would then have to buff out the water stains. With this meter I can now monitor the TDS level in the water after it leaves the filters. This lets me know when the TDS is getting too high and I need to regenerate the filter media. Also, now I know when to change the fill because the water coming out still has a high TDS after multiple regenerations. Basically, it makes my life so much easier because I don't have to polish water stains. because the medium is full and needs to be regenerated. I've gone through this process multiple times and have found the counter to be accurate and consistent. I wish I had one like this!
