I'm in the process of setting up my 1000 gallon system an I plan on running between 9,000 and 18,000 gallon turn over rate per hour. I am curious what type of filtration you are running how many pumps what you using to Polish your water how you have your uv setup in such a high flow system and if the high flow causes issues with sand in tank as well as if filter media is adversely affected by the fast contact time opposed to a slow flow tank
