Ok iv saw electric water testers , they apparently give constant reading of the important things like Gh,ph,ammonia,nitrate,nitrite,KH
My question is do they work ?
Does anybody use one ?
There like £100 and would like one rather than using colours in test tubes but for that money I’m reluctant to buy without some advice or experience
