Hi there. I'm new to this forum so forgive me if I've posted in the wrong area. I've had my raised pond which I built myself for about 1 year now and I transferred 3 shubumkins into it from my house tank. All was good and they loved their new surroundings. I bought 6 goldfish and placed them in and all was still good. I noticed that I started to get blanket weed taking over my small pond so I dosed it with clear water blanket weed treatment. A few days ago I noticed one of the little tidlers had a red sore on its body so immediately changed around 20% of the water and replaced it. I gave the pond a dose of tetra tap water treatment and medifin tetra and segregated my little sick fish. Have I done everything right or do I need to do anything else. Please help as I really like my pond.
