hello, I currently have a 20 g fish tank I am finalizing the cycle of my tank, my issue is my current filter might not be strong enough it's a Marina a s20 in the back type, as water has been cloudy more then 2 days, I can't use a different filter on the back since they are too bulky and my tanks hood doesn't really fit many tank filters I have done a few, whenever I can do a larger water change I will try to fit my tank where it has enough room to put a larger filter on the back. but for now I have seen some that can be put inside the tank like a corner filter and some that can be put inside the tank tetras brands but not sure if those can be in full water tanks, I was just wondering if anyone is using one of these do they work good? any other recommendations for a filter I can use with limited thank room and hood space I have had cannister filters but they are pretty big and lots of issues with it,I am doing regular PWC anywhere from 10 to 20% and we don't over feed out Molly.. thanks
