Doing away with green sand filter, have ? on reusing tanks

[PEW]

We had a well with high iron which was treating with a neutralizer and green sand filter, which did a fine job. We recently have replaced the well and, thank God, no longer have the iron problem but still would like to treat the acidic water.

My concern is that either of the existing tanks have a considerable coating of iron that I suspect will effect the taste of the water if I were to reuse them as a
neutralizer. Does anyone share my concern, and if so any thoughts on cleaning the iron coating out of them. They are the standard 9x48 inch polyethylene.

Super Iron Out is readily available. There may be something stronger, but that is often recommended for use in cleaning rust in softeners.

Citric acid, muratic acid etc, just use caution while doing it, proper safety techniques must be followed, the obvious stuff, well ventilated areas, do not cap the systems, proper PPE, waste disposal etc.

Thanks, will give Super Iron Out a shot, save the heavy duty stuff as last resort.

I would put muriatic acid at the strong end, but citric acid is not so heavy duty. That is used to clean coffee pots and more. And it smells better than Super Iron Out.

Note that Ditttohead has cleaned out tanks, and I have not.

You can get it cheaper, but these guys are amazingly fast and they usually have everything in stock. http://www.mcmaster.com/#citric-acid/=ygce4l

You could even use the industrial strength Lime away, CLR, etc.

Please be careful, some of these acids are very dangerous especially when they start to react.
