“Both me and my son who is colour blind test out water and this is a must have! We can both test one after the other and get the same level! Good quality and great cost going forward as reagents are cheaper!”
“Great product and easy to set up. The app could be a little better but is easier to use than some I have tried in the past. I could see the difference the lights have made to the tank after a couple of days. Expensive but worth the outlay.”
