hullo every koi keeper around the world.guys i need your opinion as we here in greece we have not the experience in koi ponds.bottom drains?this is uknown world to the pet shops here.skimmers i can find from pool constructors.anyway i m thinking of ordering all the equipment from england.yesterday i did the excavation for my pond.it will be about 12000 liters and im thinking of using a nexus easy 200 with a 110 aerated bottom drain some sort of veggie filter instead of uv a skimmer and two 1 1/2 returns and the last away 2 inch return.due to limited space the shape of the pond is like a corner the deepest poind were is at the bottom drain at 120 cm and the shallower at 80 cm.at the corner will be the waterfall.is my thinking correct of the equipment?i would apriciate any other advice you could give me only before i pour the concrete.thanks.
