Hydrometer (Free)
 

I bought a good quality refractometer and got it today. So I decided to compare the specific gravity readings against 4 hydrometers I have kicking around.

3 went in the garbage asap.

It turns out that the old Coralife Deep Six was the only one that was right on the money!(I've bought 3 others after this one.)

I don't realy know how much money I spent over the years buying these things, but I bought them quite often and never realy knew which on was reading right.(Since they varied quite a bit.)

So If someone is just getting into the hobby and is looking to save a few bucks, you can come by and pick up this hydrometer that actualy reads correct for free.

If you live in south calgary i would be happy to take it.

I'll take it, even if you don't live in S. Calgary :smile:
