Those CAEs may get pretty aggressive real quick. Watch for this and remove them if you have to. CAEs are not good choices for a ten gallon, they get huge and aggressive.
Test daily and let your results tell you when to do a PWC. If your ammonia or nitrite get over about 0.25ppm do a 50% PWC right away. When your ammonia and nitrite stay at zero your tank has established a bio-filter. After that keep the nitrate below 20-40ppm.
