Hello and welcome to Fishlore... Hope we can help.

About the bubbles.. do you have an air stone running? Is your filter flow to strong? These are things that can cause the bubbles. Usually when you fill a new tank with water you get the air bubbles all over the tank and decorations etc. But I dont believe that is what your talking about.
On another note, your tank is only 5 days old andreally is not ready for fish yet. It has not completed the nitrogen cycle yet and contain harmful ammonia, nitrIte and nitrAte levels. Tho this early in the cycle, you are probably just showing a lot of ammonia which is not good. Or it may not show any ammonia if you have not 'seeded' your tank with either fish flakes or pure ammonia to start the cycle. Which I assume you havent done yet. A "clear" water is not a sign that your tank is ready for fish tho.Your aquarium info shows that you do not know what your water parameters are and that is a good place to start for the success of your tank. You need a water test kit to find out where you are in the cycle. We mostly use the liquid test API over the unreliable test strips.
I would suggest doing some reading up on the nitrogen cycle here in Fishlore and see what you need to do before adding any fish.
