Swing Arms ARE HORRID.

I ordered a Milwaukee. I will buy another floating for backup. I LOVED my floating hydro and used it all the time. My Superman is open, thank God!

Eric, be careful how fast you adjust that salinity... it can have a very nasty effect on all of your critters, especially your fish, affecting their ability to osmoregulate.

I finished that already.... Everything seems fine, but I will keep a close eye out.

Over the years we have had very good luck with old school floating hydrometers. We also like to use refractometers. Whatever you use, you should test them on a regular basis.
FYI: We have the old school floating hydrometers in stock for $9.99. They are only $8.00 for Maast members !

We also have the Red Sea 34 gal Max for $450.00. These come in black or silver. We also have the matching stands for $100.00. In the future, I will try to find time to post notice of more great prices.

Only thing I even use my swing arm for any longer is when I mix up saltwater for water changes until it gets close enough to start using my refractometer, I have an old floater laying around also somewhere. I really should throw it back into one of my overflows to keep a constant eye on it.

I still cannot understand how my fish/inverts/corals are still alive, and I can give God another high-five for saving my tank.

Ive seen salinity at 1.040 and everything appeared to be doing fine. Dont get me wrong, I wouldnt recommend that high of a salinity to anyone, but it happens. so long as the shock of busting your salinity down so low so fast dosnt kill anything, Id say your good.
and the thought of god high fiveing you back over your fish tank is classic. many giggles.

Anybody use one of these?

I must be WAYYYY behind, because I have ONLY used 1 swing arm for the past 2 years EVER! I've had good luck. I keep my swing arm clean, and free of bubbles when i test the water. Whatever the ACUTAL salinity is, I just make sure that it is exactly at "1.023", and make sure that it NEVER changes.

And that's EXACTLY how you end up in Erik's situation... They will change calibration slowly over time.

you got a link to that digital meter?
