I've researched it extensively and have tried everything under the sun. I have successfully rid the system of multiple types of dinos. When I was answering your first question about if I had dinos or not, the answer was not super simple because its possible I dont but this last area of the aquarium that is showing some signs of possible dinos have been inconclusive. the thread I shared has videos and pictures but even experts like Taricha werent able to tell.Truthfully this was the thread I used to get good info.
Some of the treatments are quick and easy, some require additional equipment (UV filter) but imo this is the first thing you should get taken care of on your journey to a functional system.
