Rio 125 For Newbies

[BuzzbiesBubbles]

Hello I'm looking for some advice.
I have recently purchased a Rio 125 with fitted filter. Since then I have brought some rocks, ornaments, a background and gravel. Now before my next steps I have a few questions:

1) Do I need an air supply?
2) Do I need to test my water?
3) How long do I have to wait before I add fish?
4) Are Mollies a good fish to start with?

Thanks in advance

1 no you dont need a air supply, if you want one you can add one for effect but as long as there is water movement on the top the fish should have enough oxygen
2, yes to start with, it helps alot knowing where your amonnia and nitrites are at
3, you can add fish when theres no ammonia after you'v cyceled a tank this should take 3-5 weeks but it all depends on water ect, have you read about cycleing a tank?
theres 2 types of cycleing fish in and fishless, i bet you can tell the difference between them. but read the beginners center about cycleing theres a link in my sig

4. live breeders like mollys are fairly easy to keep and a nice starter fish, i think there relatively tough
