I'm working with my 8year old son to make his tank clear. I help him clean it he does most of the work I just help with the heavy stuff. But his tank still not clear. It's a 55 gallon
HOB filter up to 75gl. I check the wart ph is good ammonia is low. But still has a haze. Was wunddering if a submersible powerhead would help or not worth the money please help me out. Thanks
