i am noticing greenish round algae spots at the back wall inside my tank. i have a 12 gallon aquapod and it has like a plastic back wall that separates the main tank from the filter section where the green algae is growing. i am having a difficult time trying to get rid of it without scratching the plastic.. (i tried using a spoon).. any suggestions to somehow get rid of it without scratching the plastic? thanks btw i attached a photo of it as well.. maybe someone can tell me exactly what it is. thanks
