We have two smallish ponds with fountains using pumps but both get a bit of algae growth in summer along with mosquito larvae. I have been managing them using chlorine but have thoughts of getting them clean for some fish to help and also for our two boys. I have kept tropical fish in tanks before, everything from our eldest sons little 17l he has now up to a 250l tank I had many years ago. So I have some experience but not exactly for outdoor fish, if I can call them that.
Any thoughts on equipment, fish, water treatment, etc? I don't want to spend thousands and breed some rare variety of koi either.
