Hi Myles, welcome to AA
Two filters are fine. Clean water is good!
How many Sharks do you have? They can get HUGE, 6+" long and 3"+ tall, and about 2-2.5" wide. The are not suited to a 20G tank, more like 60G-72G. They also can become territorial, and in my previous experience, aggressive when kept in a small area, where they don't have enough territory to call their own, and other fish will be in their way and suffer because of it.
I have just recently lost my, similar Red Tail Shark, who was the largest one I had ever seen, a female about 7" and she was at least 8 years old (72G tank). She was one of my very favorite fish ever and really loved cruising around the tank, making sure "her" space was clear of other fish!
This pic was when she was in a quarantine tank.
This is the tank which she ruled.
