I find it hard to believe you have 200 ppm by your description. In fact I've never heard of any well having that much. Are you sure it wasn't a typo and 2.0 ppm instead?
Regardless iron shouldn't be a problem in your pond especially a pond that size and the amount of water you are supplementing.
I deal with iron from a well at 2.5 ppm into a 100,000 gallon pond (1/10th acre) 45 gphm 24/7 and it's not a problem with my trout.
Also keep in mind for an accurate iron test it needs to be on site. If you send off a sample it won't be accurate.
I didn't say I did, I said I read that was avg. for ground water, based on what you are saying I must have read it wrong, will go back and check it out as soon a I have time. These old brains aren't what they used to be, not that they were ever any thing to write home about!
Was going to drop a sample at the drillers office today, didn't say anything about it needed to be on site to be accurate. I guess we'll see...............Budster
