hi i was wondering what is going on to my tank, so recently i had an algae bloom and it messed my tank up bad, so my friend told me to buy a 50 gallon filter for my 20 gal so i did, left it overnight and in the morning i looked the front of the tank looks pretty clear but on the side it looks like it's cloudy in the inside? not sure how to explain it, plz help. btw i do not want answers relating about my tank size for the fish, i know it's too small for them but that's all i have
