You can sound the seams with a small hammer. Rusted soft spots will not ping but thud. An air compressor can Make 1 gallon of water per horsepower per day. All that water does not condense in the tank. Much of it condenses in the hose and or tool and the rest passes thru as vapor. Oilling tools is the key. Not just at time of use but before storage oil em up. That bit of water sits in the tool and can ruin it while not being used. There can be rust getting down the line as that is a common problem. Use a simple particulate filter to protect your tools a bit more. A coating of rust actually is the only protection a non coated tank has. Remove it and it rust again right away. Keep em drained and check them with a hammer from time to time.

Yea I got that one too

#15. Strain the liquor out of a broken bottle. Go ahead and laugh, but I did just that. I had been out of work for 4 months, and after 5 interviews and a ridiculous wait for a "yay" or "nay", I was hired. To celebrate, I bought a bottle of Ciroc and a bottle of Hypnotiq... that's about $50.00. I get home, and as I'm headed to the front door, I DROP the bag and both bottles break. I almost cried. The Hypnotiq was completely gone, (I hope my Hostas enjoyed the runoff...), but the bottom third of the Ciroc bottle landed standing up, and there was still vodka in there. Thus, the 15th use for a coffee filter!

Those iron/manganese levels are fairly low so should be easy to remove. What is your concern with the chemical injection prior to the terminox filter? Are you concerned about handling/safety, or is hassle the main factor? Your numbers are low enough that a water softener would remove the iron and manganese successfully. This would eliminate the more aggressive chemical injection, but would require you to add salt to a brine tank. Here is some additional information about iron/manganese removal: Softener: A softener with specialty resin is capable of removing dissolved iron and manganese. Iron/manganese will slowly foul the softening media and a bit of extra maintenance is required to removed the iron/manganese. I can provide details if this option is of interest to you. Oxidation/Filtration: An oxidizer such as ozone, air, or chlorine may be used to react with the iron and force it to become particulate iron that can then be removed via filtration. A typical setup would involve the oxidizing unit, a holding tank, then a media filter. This type of system works quite well, but takes some expertise in sizing - you would want a water treatment pro that you trust to help you with this option. Oxidizing filtration media: This type of treatment consists of a sealed tank filled with one of several media. Water passes through and is oxidized and filtered by the media. These are relatively easy to operate and what I would recommend for the average homeowner. There are several different media that can be used: manganese greensand: water runs through for treatment. The media must be regenerated with potassium permanganate. Care must be taken with dealing with potassium permanganate as it readily dies organic material, such as your skin, a purple-brown color. Some people are quite comfortable dealing with the chemical; others are not. Synthetic greensand: This is essentially the same as option (a) but consists of a coating of greensand on a silica sand core so does not require as much backwash flow. Service flow rate is 2 - 5 gpm/sqft. Backwash flow rate is 12 gpm/sqft. birm: This media acts as a catalyst to force oxidation of iron. While it does not need to be regenerated, it does need fairly high dissolved oxygen in the water. If your water does not have adequate dissolved oxygen (and it probably doesn't since it is well water), air injection would be necessary prior to the birm. Additionally, birm requires a minimum pH of 6.8.. Service flow rate is 3.5 - 5.0 gpm per sqft. Backwash flow rate is 11 - 20 gpm, depending upon water temperatures and desired bed expansion. pyrolox: an ore that oxidizes then filters the iron out. It does not need regeneration, but needs to be backwashed (to rinse out the iron) at a high rate. pH range is 6.5 - 9.0. This type of filter works very well, but backwash is critical. Service flow rate is 5 gpm/sqft. Backwash is 25-30 gpm/sqft. Backwash daily. Terminox: Similar to Pyrolox, but a...
