“Great system. I love theft that it comes with 2 separate magnetic mounts, so I can have the optical sensor in my sump section, and the backup float switch in my DT or separate section of the sump if I want to. The flow rate is variable using a small know inside the case, low (nano) to high flow. I found with low (nano) selected it can't manage the 1m head height to my tank. by turning it up a little whilst the pump is running you can set to the exact flow you want. Seems great so far, and easy to set up. I looked at others but this one has been around for years and has proved reliability, and the benefit of a second backup float switch, and it knows if it is topping up longer than usual and also switches off as another fail safe.”
“Excellent device. Saves messing around tipping RO water in the tank every day. Easy to install. Only issue I had was I have a juwel Rio 240 and the covering around the top interferes with the magnets connecting. But I bought some metal notice board magnetic strip and stacked it on to of it self until it made a level with the rim and then could attach the sensor platform and outside magnet together.”
