Internal Memory getting low despite apps are moved out using Link2SD

There might be similar questions. I don't want to open those old question. This is what I have done: * I have rooted my phone. * I have installed Link2SD. It was working good. Suddenly I started to get interal storage full warning. I uninstalled apps one by one. I got some space in internal storage. I got about 80MB. I should get 150MB. Anyway, I am now installing apps one by one. Whenever I install an app, the internal storage is going low. Once I moved the app using Link2SD, I am getting some space. But the problem is, I am not getting the same amount of space. So if I install few more apps, the internal storage will surely go down and i will get warnings. What is the best solution to keep the apps in SD card? So I can keep good internal memory.
