DANOPLUSSmart pH ORP Controller with Remote App Monitoring & Dosing in Water, 3 in 1 pH/ORP/Temp Meter Replaceable Probes for Hydroponics, Aquariums & Pool

This unit really helped when I started hydrophonic gardening. Help keep water balanced so I didn't have to check daily.

Bought 2 of these for 2 tanks. One failed within 24 hours by the dosing pump outlet remaining on, lowering ph and killing fish.The other one failed within 24 hours in exactly the opposite way; raising pH in the tank not switching dosing outlet on properly, killing fish.THERE IS NO DOSING PUMP WITH THIS KIT, DESPITE SAYING IT DOES IN THE ITEM DESCRIPTION.THIS ITEM IS JUNK

The media could not be loaded. The instructions say to not have the 'too high' alarm and 'too low' alarms on at the same time, however there isn't an off or on setting. What I learned was both alarms apply power to a device. Since I'm using this to add kalkwasser to a reef aquarium to raise the ph when it's too low (consumed by corals) and not CO2 when too high, I merely set the too high alarm to a level it won't reach, and the too low alarm to 8.30. This seems to work perfectly. That said, I'm going to return it, spend $30 more and purchase the Milwaukee one since they make outstanding tools already and I trust them more. While theirs doesn't have a mobile app, I don't need the controller to be controlled from my phone or Alexa.

Simple to calibrate but the PH relay is too slow reacting. Instead of regulating the PH value, deregulates it.

Es simplemente en la pagina web de information no estaba escrito o establecido con que corriente se usa.Si se envia a un pais con ac220 se debe tomar en cuenta que el usario normal no lo sabe como consecuencia el equipo queda inutilizado al conectarlo.el equipo comprado ya no es relevante para mi .voy a dirigirme y comprar en otro web con mas informacion para no perder otra vez mi dinero

Hard to use software didn't support it ..to new ? Doesn't turn on for low pH setting .. or heat control. Was really excited and really let down
