I have two 10 gallon tanks, a 20, and a 29. I mainly have shrimp and guppies. I'm curious if anyone on here has any tips about getting rid of algae growth? Three of my tanks have bad algae problems.
I would go to the pet store and get about 15 to twenty small snails that they gave me free. They cleaned up the algae and the fish would eat the snails too.
 
I'm actually a fish breeder. I have a 20' X 20' fish room filled with fish. I have Discus, Bristlenose Plecos, Dutch Blue Rams., Jet Black Rams, and Electric Blue Rams., as well as a 125 display tank full of various Rainbow fish and a 30 gallon with red fresh water fish.

I may be able to answer some questions here, but there are many freshwater fish I have not had experience with like African cichlids for example.
 
Algae is generally from too much light or too much pollution. Either over feeding, or not doing regular water changes to remove the nitrates.
I try to do water changes every week. What is confusing about it is that the three tanks with problems have barely any fish in them. The 29 has a couple guppies and a tetra (I'm planning to get it a school soon), the 20 has around 5 guppies, and the 10 has a couple red cherry shrimp. I rarely turn on the lights for two of the tanks, and the third one only gets 5 hours of light. I think part of the problem is that the tanks are by windows. I'm pretty sure it's not overfeeding, since the shrimp don't get fed at all.

I have a lot of pest snails. :p

Sunlight will feed algae. Have you run any tests for nitrate levels? Sometimes you get some readings coming right out of the tap too which isn't good. Also having algae can lower the readings, so it isn't always an accurate reading.

Moving the tanks away from direct sunlight may help, or adding some live plants. Regular filter cleaning and maintenance can help too. I know in saltwater systems they use an ultra violet filter to kill algae. I'm not sure if they are applicable in freshwater or not.

This kinda covers most of what I said, but is a bit more informative.

I didn't think about the possible nitrate levels in my tap water. I have live plants (which is why I don't completely blackout my tanks). I actually have a couple uv filters that I got for an unrelated problem..

Thanks for the help and advice. I think I'll try to do more water changes and limit the light to see if it helps, and if that doesn't work I'll test the water. :)
