Salt Measurement HELP!!!!!!!!!!

[lcc]

I bought a new hydrometer yesterday after reading how measurements can differ. I was shocked that my old device (the box type was so far off). My old reads 1.23 and the new read 1.35.
I brought the salt measurement down to 1.28 last night and will drop it down again to night. I did not know if bring the measurement down too fast would shock the fish. Or should I wait to bring it down over more time? Advice Please!

WOW that is way off.
I would take a sample to the LFS and see what there reading is before I made dramatic changes.

Yes, I agree with twoods, bring a sample to your lfs and see if your new hydrometer really works, maybe it's a dud. And yes, don't drop it down so fast, it's not good for your fish.

That is a big difference, I know I had problem with the box type awhile back, but it was not that far off. I would get a third opion before you start making changes. I would not make that big of a change that fast, do it slower, You don't want to shock the fish, if the reading was really that high they already were stressed out. Good Luck

Thanks for the advice. I also have a glass hydrometer and will measure the water with it before I take it to the LFS. Are the glass float hydrometers any good?

dont know about those. i use a deep six hydrometer. i like it alot, keeps my hands dry and theres no stupid line i have to fill to. i also dont get those stupid bubbles on the needle. i dont know how accurate it is though. ill have to test now that i read this.

There was another post not too long ago about this and I was amazed at the different results people were getting when they compared on old one to a new one. The old ones were a lot higher. I guess it pays to clean them or just buy a new one every once in awhile.

As I mentioned before I buy a new one every year just because it seems reasonable to do with the use I give mine. I have checked new against old and even had the lfs check mine with their new refractometer. The owner also checked all of his needle types he was using and the most any were off were plus2 and one was right on. I did buy one the beginning of this year that was way off my old one I returend it for another one and it and the old agreed within 1 point. The floating type which I also have is too hard for me to read while it is dancing around the tank so I don't really use it anymore.

I took both my meters (old and new) to the lfs and the new one was right on and the old measured everything very low.
So, everone should purchase a new meter every 6 to 12 months in my opinion to assure that the water is constant and the measurements are correct.
