Somewhat recently I dived a quarry that was under consideration as a scuba park. It was deep (150+ ft) and about 15 feet viz. There were actually two quarries. I am curious, however, what makes the water have an extremely metallic taste. Had a water sample taken but nothing appeared to really stand out. Archman, any comment on the metallic taste and why do I have a third eye now?
Well...just WHERE in Texas makes a difference. We don't need the old ladies address but the town name or general area would help. Some areas have high levels of iron in the ground, some are very alkaline from the limestone, etc.
I'm not from TX but I have done a lot of water treatment for shrimp hatcheries. Dee is right, maybe. High Fe (iron) can cause that taste. Try put 4-5 ounces of Clorox in a 5 gallon bucket of that water. If it turns orange brown in a few minutes, it is probably iron. (This shouldn't cause any health problems but you may have problems hatching baby fish in it). Alkalinity by itself shouldn't cause the metallic taste. Pure seawater has high alkalinity compared to most fresh and it has no metallic taste.
