Grainy photos and troubles in macro

[o.c.d.]

"I'm still having some troubles focussing in macro. It beeps saying it has focussed, but when I look on puter it is not focussed."
I was having the same problem I now shoot super macro with digitial image stabilization more (or pic of shakey hand). It works good i've also read about using a cell phone holder stuck to the outside glass for stabilization. A tri pod works to just not for in tank shots. I should mention I'm using a Olympus1030
