| Terri: A local club member had her pond re-done with a new surface, but kept the same basic filtration and water source... a well. Shortly afterward, she began to have problems. Her house water came from the same well and all seemed normal in the house, but in the pond she had "brownish stuff" in the water and settling out on the surfaces. Henry visited her pond to check it out. I heard about it, but did not see in person. The problem went on for months until she tried a product that killed most of her fish. She tried various things along the way, but did not get a professional lab to assess her water. I suspected that there was an iron-based compound in her well water that precipitated when mixed with the organics in the pond. I also speculated that the pond work had nothing to do with it, and instead it was related to local drought conditions affecting her well water. Lots of speculation on my part. The solution was adding activated carbon filtration to the water line. Over a couple of weeks, the problem went away. HenryC was instrumental in saving the day. The curious aspect is that the same problem was never experienced in her house, only in the pond. Whatever was/is in the water that was at the root of the problem seems to be removed by the carbon filter. But, the hobbyist has still not gotten a thorough water test done, only a basic "safe to consume" public health department test. So, maybe it was just coincidence that the carbon 'worked'? ... HenryC has better knowledge of the situation and may well correct my recollection. |
