I would like to informed about in our Hotel we have courtyard ponds 4 No’s & lotus ponds 6 Nos. All the ponds everyday morning we are filling up a lot of water I think because leakage or floor grounding .This is not suitable for energy consumption also daily basic we need to clean each pond and drain out all water. Do you have any solution? And also un appearance after cleaning 1 or 2 day because without filtration system .
