My refractometer has been acting up before it had my tank at 1.024 now it is calibrated with same thing I calibrated it with before and it’s now saying 1.033, that is not posible this really is confusing.
Oh man!!! Now this might be bad! These fish are over salted! This happened to my brother with a flame. And did the same thing. Dead on day two. The other fish are used to it. My brother went from 1.021 to 1.028 and the angle littler was acting like the clown. This was in my brothers ordeal. But you need to get a tropic marin hydrometer. I tell all reefers to get one! It’s a must. Have seen many failures with digital or refract system! No thanks!
My fish mean a lot more that $50 to me! So I have hydrometers, yes not just one. The reason is they can break easily being they are glass. But being careful and cleaning with rodi in a sprayer does the job and back in the plastic container it goes. I have a 500ml graduated cylinder and put the salt in it at the 500 mark or just above it by a bit. Then put the hydrometer in and read the SG and use a salinity temp correction calculator. Never fails me. Everything else you can get on the
market in the end has failed me! And cost my brother a nice flame angle sadly. He just couldn’t figure it out until I got the hydrometer out to check his SG levels.
Just an idea. Again the news the case for my brothers fish. And the crazy thing, three other fish in the tank were fine somehow.
