At last the construction process finished and I'll enjoying back my kois soon enough.
The pond size is 275" length x 157" width x 78" depth or equal to 7m length x 4m width x 2m depth. Single 8" bottom darain. Filtration system use only 2 chambers vortex, 4 chambers kaldnes, 1 circulataion pump chamber and bacteria house on the 5 trays bakki shower.
Any comment on my pond everybody??
