Сеточку в трубе можно было бы зафиксировать, поджав её ещё одним таким же колечком из кусочка трубы, а то как-то ненадежно выглядит, как будто она может выпасть наружу и рыбку засосёт туда... :))
Idea is very good. You prepared detailed video. Video quality is very also good. And finally the with Kois and working with filters it is awesome. Bro you are requested to share the name of matrial, medicine added in water. Also the names of biomedia used and names of plants. It will be very helpful to the Koi pond lovers. Thanks for such a nice and great video.
