the genius i had come clean my tank since i didnt have the time due to work used soap im guessing an didnt make sure that they cleaned it all up. now when i turn my bubbles on the top of the water gets some what sudsie. ive been changing the water but that doesnt seem to help and the fish seem to be doing perfectly fine so do i keep doing water changes or do i just leave it alone and let the soap finaly work its way out?????????
