| I have to second Dick's warning about handling muriatic acid. I use it to clean my air stones. I wear a fitted cartridge air purifying respirator using cartridges made for use with acids. I also wear rubber gloves with 12" sleeves and a clear full-face mask plus goggles. Over kill by some but this stuff is dangerous to work with. I would not pour the muriatic acid into the pond from more than about 4" above the water surface to avoid splashing. Just be careful, the vapors from this stuff can damage your lungs. I have read information from others that suggest the use of phosporic acid instead of muriatic. But have not had any experience with it.
