Combo pH / temperature / Electrical Conductivity meter I borrow from work..... ( I am an Enviro Officer....)
Refractometer. Will never go back to a swing arm ever again.
refractometer from DR Foster + Smith
Floating glass, lets me track the temp and salinity/sg in one sweep...very nice and extremely accurate
Digital Temp/Salinity/Specific Gravity thingy I picked up on nano-reefers
best method of all.. taste. I always go by taste of the water.
just kidding, its too early in the morning
refractometer ever since the beginning. i still skimp on other test kits though.
refracto all the way!!
refracto=one of the best things I have ever bought
Just won an IO floating arm at a club raffle. It is at least .004 off. I'll stick with my floating glass hydrometer!
I origionaly bought waaay too much LR to set up my tank. Took excess to the LFS and traded for a Refractometer. Happy ever since
Refractometer. Wouldn't ever go back.
I think this is more to heart of the subject , if your using a hydrometer , what do you actually keep in your tank ? Are your corals, fish , inverts that sensitive to salinity level? I bought a hydrometer and it varies between 1.022 - 1.0029 every time, thats a big difference , especially when I am trying to keep it at 1.024 , is it really 1.017????? or 1.029??? I personally would rather know exact measurements. I am a beginner and wonder is salinity level being off by this much going to cause a real problem? I'm sure I'm not the only one who got an inaccurate hydrometer and they seem to be fine, plenty of people here have said they use a hydrometer so maybe having your salinity levlel off by .007 -.010 isn't such a big deal??????
Please tell me other wise and would you nice folks using hydrometers tell us what is actually in your tank? Are you beginners like me or do you have a well established tank with thriving corals and fish???
hydrometers aren't that accurate. The first of I had has bad, i almost did some damage to my tank. I use a refractometer now. They are worth the extra money!
I use a glass bubble hydrometer, and it worked great until I dropped it X) I calibrated my new one against a refractometer, and it's off by .001. The thing is, it will ALWAYS be off by .001, regardless of what salinity I'm trying to acheive, so I'm still getting results that are just as accurate. I just can't justify paying 10x as much to get the same results. You don't have any issues with gunk building up on the glass if you don't leave it in the tank. I can't think of anything easier to clean salt off of than the outside of a smooth glass cylinder.
swing arm hydrometer
After too many different readings with hydrometer switched to refractometer.
refractomer, i had 4 swing arms from 3 difrent brands and non of them actualy worked, it was weared, they all would point straight up nomatter what i did. so i finaly just got a RM and it worked great.
Refractometer for sure.
Refractometer here.....I can see no reason not to and plenty of reasons not to use a swing arm...
I've used them all. By far the easiest and accurate in the Refractometer.. Just my two cents. But it is good investment.
refractometer from http://www.drsfostersmith.com/ i love it
