Tactics Trainer

How many problems should i do a day.Normally i am available 6 and more hours a day. How much should i take on making my moves (Normally its not a problem because mostly i use my phone). And How much time on Live!? 

15-20 minutes a day on Tactics Trainer, and then as many games as you want.

I normally do 50 tactics each day

There's no harm in doing lots of tactics a day - I do regularly. But your brain will only absorb a certain amount of patterns a day, and after that point there's not much point in continuing.

but would you say 50 is alright i normally get between 1740-1800

I do 2hrs of tactics each day, but in 1hr blocks, but I have a lot of spare time :D
