Kessil gooseneck paint issue

[Lazysavage]

So I have been struck by the paint issue with the kessil clamp on the bottom of the goose neck I saw that this may happen. I may be on to a reason why. I noticed that the aquarium I keep at work has a lower level of salt (1.025)The one at home is much higher.(1.030). Today I was changing the water in the nano and I noticed the paint was gone on the clamps so I did what every normal reefer does freaked out ran around in circles blamed my mysterious chaeto breakdown on it and finally calmed down and did a little bit of searching for similar experiences. It appears to happen with no real reason. I recently swapped out my “old (not so) faithful” hydrometer (plastic kind) for a refractometer. And found a difference of .005 sg. Now not saying this is the cause but perhaps a piece to the puzzle. What do you all think? Apologies in advance if I did not see a previous thread first post!

Higher salinity levels may be a bit harder on painted surfaces, but IMHO the difference is minimal. It's more likely the original paint job was crappy.

As for your hydrometer being inaccurate, just note that yes, it's inaccurate, but probably always by 0.005. I have one that is off by the same amount. I've been using it now for over 5 years and every 6 months I check it against a freshly calibrated refractometer and it's ALWAYS off by 0.005. So I measure my SG and it's 1.020 or 1.021 and the I add on 0.005 and I'm right where I want to be, at 1.025 or 1.026. I find that way faster than a refractometer and it really never needs to be re-calibrated. I just do it every 6 months as a test since most people on here think hydrometers are crap and refractometers are great. I disagree.

Lol I have to say consistency right. If everything is fine and that hydro is consistent you will be successful. My concern was that the salinity could impact the fish over time. Now that I know it is off I wouldn’t be against using it. As you said it is faster. I have been using one at work (ocean science teacher) and I have grown coral with that the fish seem alright but I wonder where my salt really sits. Not that I will change the coral is happy and so am I. Thanks for the thoughts on the clamps I have to contact Kessil.
