Post a picture of the algae so we know what type it is, and an entire picture of the tank so we can see how it's planted.
What sort of light unit is above the aquarium?
How long is the light on for each day?
What is the Kelvin (
K) rating of the globe, or the colour spectrum?
What are the tank dimensions (length x width x height)?
How often do you do water changes and how much do you change?
Do you gravel clean the substrate when you do a water change?
Do you dechlorinate the new water before adding it to the aquarium?
What is the ammonia, nitrite & nitrate of the water?
What sort of filter is on the tank?
How often and how do you clean the filter?
What is the
GH (general hardness),
KH (carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website (Water Analysis Report) or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg:
ppm, dGH, or something else).

As a general rule you don't add fish to solve a problem. You find out what the cause is and fix that.
Algae grows anywhere there is light and water. If you have lots of live plants in the tank, algae won't do as well. If you don't have any live plants in the tank, then algae will grow instead.
Loaches should be kept in groups of at least 6. They have a pecking order with a dominant female ruling the group. The females get bigger than males and the dominant female will be the biggest fish in the group. Once these fish have a group, you have to be careful about adding new fish to that group. Try to add younger smaller fish so there is less chance of them being killed.
