Welcome to our forum Bambam.
The bubbles are not a problem. Water in the pipes coming to your home is under pressure, when you take the pressure off, the gasses in the water come out as bubbles, just like the bubbles coming out when you open a bottle of soda.
The lack of a cycled tank will make your task of keeping any fish alive that you already have into a real job. Forget just adding Aquasafe. Instead a large water change is probably in order. Be sure to treat the new water with a good dechlorinator. Aquasafe is a dechlorinator that should work for that purpose but is not a substitute for a water change. The rest of the claims for Aquasafe or almost any other dechlorinator are 90%+ sales hype, 5% pseudo-scientific mumbo jumbo and at best 5% useful information. You can safely ignore all of the other claims and just use whatever dechlorinator is cheapest in actual use. For me, with the sources I have available, that has turned out to be Prime, because it is so darned concentrated. For you it may turn out to be some other brand.
