Welcome Brittany!
You really need to get a liquid water quality test kit and post the results here asap.
Algae protects your fish to a point, but too much can be a bad thing.
API makes the best kit that most of us use.

Also pick up a separate KH/GH test kit and let us know the results.

Florida has a bad problem with high phosphate levels in the water. Make sure the master test kit has a phosphate kit included. If a phosphate test isn't included, get one.
Once we have the numerical results from your testing, we can help.
Don't add anything else to your pond for now.
