i have a dozen goldfish, i know its a small tank(10 gal.) but thats all i can afford at the moment. i use city water so i dont know why i would have hard water? and i dont have any live plants. should i get some? i do a water change (1/2) every month. i feed the fish twicew a day and there is some natural light that gets to the tank. other than that its my flurescant light that is on from 5 am til 9 pm. any other info needed to fill in the question lewt me know. thanks

It's calcium, potassium and other fixed deposits that have formed and other minerals from the urine and minerals left from fish wastes and their chemical reactions in the water.

It's the iron mineral in your water collecting. Your water must be as hard as mine. It will not hurt anything but doesn't look great. I just keep my water filled to the top so it doesn't show.
The algae, depending on what kind is probably from to much light. I don't know what kind of fish you have but live plants would help. 8-10 hours of controlled light would keep down the algae too. Along with not over feeding.
Good Luck

the others have answered what the 'white' stuff is, but you should be changing 25% of the water weekly, be feeding them less often( remember in the wild fish can go up to 6 weeks without food ) so feed them every 2 day will be fine, and you probably have a few to many fish in your tank
good luck

calcium in your water, and maybe some chlorine buildup is causing the chalk like substance. It may never stop. I had a healthy beautiful tank for years and I always had to wipe that stuff off.
As for algae, you need to get a testing kit to test your water. They are cheap and will tell you if your ph is too high or low.

Calcium and trace metal deposits that are left behind after water evaporates.
Might try changing out the water a bit more frequently, it's either very hard or you havent changed it in a long long time.

It is just all the minerals in the water that are left after water collects, and evaporates. Just wipe it off with a wet paper towel.

Lime, calcium and other hard water deposits. Could be algal growth. You can clean it w/a fine abrasive, but no strong chemicals.
