I am totally onboard with the corrective criticism tone of thought, it just seemed like the criticism i was receiving was not of that tone. More like hey your idea is never going to work this is the system i sell and you have to use it for your pond to work. I totally get that people do this for a living and might have a superior system. I at no means need a top of the line system. My pond has some crappie (not stocked must have been dropped in by bird feathers) LMB, CC, and some pan fish. I bought this house and fish were already in there. I am not looking at raising the best fishing hole in the world. I just knew my water quality sucked due to the excessive amount of duck weed taking over. I am not going to put any more chemicals and now that i have aeration i should keep the fish from starving out of oxygen until next spring when i can keep the duck weed help back. If i plan on upgrading my system i will definitely look at a vertex diffuser just for comparison only. I think the pool is a great way to see how the two work. And i am sure some people would like to make their own set up rather than buy.
