hi dont know if your problem is cuased from the shade .my pond has a cover over it which lets in no light at all i have it lit up by ordinary garden spot lights which is no substitut for sunlight this was done for my own viewing purposes my koi are all healthy and colour patterns are strong with new colour coming through all the time . as for what bulbs i dont know most of the bulbs are usually for plant life
