Aquarium Progress

My aquarium is progressing quite well. However, the last water test I preformed resulted in 1.0 for ammonia, which is not hospitable for fish yet. Luckily though, the nitrate test resulted in a 5.0, which is good for fish to live in. The temperature of the water was 21 degree C, or 70 degree F which is a good temperature for the tropical fish I plan to buy. The only noticeable change about my aquarium is the algae growth on Squirdward's house and the water is not turbid at all. Other than that, not much has changed.
