Some notes on algae...
Here is what i used to tell all the customers that asked me about algae when i worked at a tropical fish store.
GREEN ALGAE
Algae is a plant, and like all plants it needs food to grow. Algae gets its food from several things found in a turtle tank.
1. Light. Set your lights up on timers so they go on and off at the same time each day, there will be no extra light to feed the algae. Make sure your tank isn;t getting any direct sunlight.
2. Left over food. Whenever you feed your turtle the piecies he doesn't eat add to your algae growth. Remove any large chunks of food from the water using your hands or a turkey baster. Feed your turtle slowly so he has a chance to eat more and waste less.
3. Turtle poop! Algae also feeds on turtle waste. Remove any large particles of poop with a turkey baster. Maybe you could add a more powerful filter. Also, keep up on your cleaning. Weekly partial water changes are good for maintaining a relatively algae free tank. Complete 100% water changes are bad, they will work at first, but shortly after the algae will come back even stronger because you will have caused your tank to recycle.
BROWN ALGAE
Brown algae is different than green algae and is not as easy to get away from. Brown algae shows up the most in new tanks, or when you havve just done a 100%, or close, water change. Although keeping a clean tank and avoiding extra light will help control it, it really has to be physically removed. The best thing to do it to use an algae scrapper and scrape it off. Also,
A couple extra notes:
1. If you have rocks in the bottom of your tank they will add to the cervices algae can grow in. You may find removing these rocks will help.
2. The turtle that is in the 10gallon, how big is it? A ten galon isn't big enough for a turtle much over the size of a 2inch hatchling. If he is any bigger than that its going to be close to impossible to keep the algae down because there is no way to get rid of all the waste because there is too much turtle for that tank. Try moving your turtle into a bigger size tank (10gallons for every inch of shell) and you may notice a significant decrease in algae.
