what no algae!

algae!

Hi,
The last tank I had, it was teaming with algae so call me nuts but I thought all tanks had some amount of algae for the fish. The ph levels are 7 and the NH3 and NH4 levels are 0mg/1 is that good ?
 
Thanx

Thanx for all the info and replies ,maybe I am just freaking out cos I lost an entire tank full of fish due to a mysteriouse disease so I am probably hyper sensitive with this tank.

THANX,MUCH APPRETIATED!
