55 GALLON STOCKING???

You need the liquid test which has a bigger range. You add/count drops until you get a colour change. This will show if it is indeed 180GH or somewhere (much?) higher.
Ok. Well I will have order that because the nearest pet store is 45 minutes from me.
 
That's a huge hardness range, from in between soft and hard to very hard. At the bottom end of the range it is too soft for many hard water fish, and soft enough for many soft water species, but at the top end of the range it is only suitable for hard water fish.

What did you test it with? Can you pin it down to a smaller range, or ideally a single dH?

I'm not exactly sure what you mean. The API GH test took 12 drops to turn from orange to green. The conversion chart says 214.8 ppm....is that wat you mean?
 
These are the 2 charts

If it took 12 drops to change colour that's 12 dH but you wrote

and I thought you meant 11 to 22 dH. Sorry if I misunderstood.
No it was the way I said it. I thought it was a range of degrees. I didn't interpret it exactly right. I went back and re-read the explanation in the directions. I understand now 🙂
 
At least it's sorted now :)

The table with the ranges for what fish - don't take much notice of that, they have somethings wrong such as mollies needing 100 to 200 ppm when they need over 250 ppm. Look at the profiles on Seriously Fish instead. They may not always be 100% accurate but they are better than most other places.

Ok thanks! I'll check out the site
