I will give everybody the instruction how to get rid of air bubbles
This is the best way... and follow these rules......

1.  Move the paltform only 2 mm inside to the resin.
2.  Take a metal or plastic plate, which is as wide as paltform.
3.  Then " of course" you have to open the door.
4.  Move the plate from the middle to right side and to left side
    (not very quickly) in 3 sec.   Do this a few times.  Now you can see
    how the microscopic air bubbles is coming up under the platform and the
    plate carries the air bubbles to right side and to left side of the vat.
    Now resin is clear above the platform and you don't have to worry about 
    them any more.

    You should do this every time before you will switch on SLA or before you
    'll increase the resin  (remember: before increasing resin).
    Now once more again point four. 

   ......... Now you'll be HAPPY.........  :-)
    We have used this method two years and it's works very very very well.
    Please let me know your experience.....!!!!!??????
