If you've no drain about the only option is fitting a retro one like this:94Gt5.0;4193011; said:How do you guys go about cleaning the bottom of your ponds? I dont have a B/D, and would love to find a way to get or make a large-scale gravel vacuum that most of us use in aquariums. There has been some sand and debris that fell into the pond, and the fish stir it up when they spaz out lol. Any ideas or suggestions are greatly appreciated!
Oh, and is it a good idea to do a water change once the pond has cleared up more, or will that re-start the algae cycle?
