Hello,your first question on max. height of trickle tower, One thing to remember is ASTHETICS!! You should want people to notice your pond and the koi! A 5 meter trickle tower MIGHT draw more attention than your koi???? People who do not know about ponds will always ask ( What is that big tower for?) And that is not the idea!That is why some people try to hide a trickle tower behind a waterfall!!!The size of your trickle tower should be in relation to how many koi you have! And remember they will grow and you will probabily want more koi in the future, so it is better to have more filtration than less! Oxygen can also be supplied by air stones if you need more! So I would say that two 2 meter high towers is enough, wnat is important is the biomedia inside them. The idea of the trickle tower is that when the water runs down over and through the bio media, this area is wet, but not submerged ( like a shower) and in this process/ after about 4 to 8 weeks you will have a natural bacteria that will start to grow on the biomedia, and this bacteria is what you want! This is the same process that happens in rivers. The pond must first be DIRTY!! so you must first put some koi in the pond, then when the water is dirty, the trickle towers should be turned on, if the water is not FIRST dirty, the bacteria you want will not grow in the trickle towers, The bacteria must have something to eat before it can grow!Also the water should not run down over the biomedia very fast or with alot of pressure, this will make it hard for the bacteria to STICK to the biomedia!!! And after the water passes through the trickle tower, it will be very oxygenated and this falls back into your pond!Looking at your design I see one thing that should be changed, The pump should be located in a way to avoid corners in the pipes! Everytime the water has to turn a corner in the pipes, this means the pump must work harder to push the water up! Each ( elbow) = resistance!!! So the most direct way is better!I would have to water go from the pump directly up and then 1 bend in the pipe that drops the water into the trickle tower. This means move the pump directly under the trickle towers!
let me know if you have more questions
