So I bought a 500ml bottle of microbacter clean to get rid of some algae, it lasted almost 2 weeks dosing two tanks the recommended dosage. Things were already looking better so I thought it worth continuing so I bought a 4 liter bottle to keep going and save some cash. Now the 500ml bottle poured out pretty cloudy with a decent amount of material suspended in the solution. The 4 liter bottle pours out basically clean looks almost like water. I’ve kept up with doing the past few days and haven’t seen the kind of response I felt like I was getting from the first bottle. Has anyone else run into anything like this where they buy a larger size of and the product seems really different than what you got in a smaller bottle? Feeling frustrated.
