Not sure how many other people have local fish stores in which you as a hobbyist have a wealth more knowledge about reef keeping than they do.
I went to my store the other day for some frozen food which is about the only thing I will buy from them anymore....actually I ended up going to another store because they ****ed me off so much.
I took some aquarium water there so I could see what they come up with for Ca and nitrates. I have several kits and know my nitrates are about 1-2 ppm and my Ca measurement taken that day with the hanna kit was 448 ppm. I am pretty anal about knowing my test kits are working as they should so as chemist I made up a standard of 400 ppm Ca in the lab.
Hanna result:....
396 ppm. Yes I will settle for that accuracy every time.
So I measure my tank 2X and got 448 and like 446. I take my water to the local reef store and they are like....your nitrates are about 10-20 pretty low and your Ca is on the low side at 400 ppm. This is for my tank water....I did not give them the standard to measure mind you. So they are telling me 400 ppm and it's really about 450 ppm.
Moral of the story is make sure you know and trust your local fish store and don't take their word as written in stone.
OK that's my rant for the day.
