Welcome to the forum and congrats on your new pond.
The majority of new ponds (and in the spring for established ones) go through an algae bloom, but it usually doesn't last long once the plants start growing and competing for nutrients. It'll pass on it's own or you can look into getting a UV.
Also, for ponds to get truly cycled you need an ammonia source, which most of us use fish waste. Added commercial bacteria alone will not cycle the pond unless the pond has an ammonia in it to feed off of, else the bacteria will die. I didn't understand this totally until I set up an aquarium, then it finally kicked in for me because it's much more critical to be aware of in a small body of water.
The link below is a simplified explanation of the nitrogen cycle that a pond goes through. Jerry - if it is against forum policy to paste links to another pond site, please remove and I'll try to verbalize it on my own.

is this from the information
Tap water kills the bacteria you have worked so hard to establish. I used to never add dechlor when I topped off the pond, but never again will I not. Chlorinated water kills beneficial bacteria and I'd rather not take the chance of upsetting my pond cycle.
