Hydrometer

[hobgoblin]

Hi folks,

I'm new to the hobby, and am still in the planning and deciding stage of starting a nano tank.

Right now, am looking for a dependable hydrometer. No doubt about it, a refractometer is indeed an accurate instrument but I'm unable to afford one at the moment. I'm looking for a swing arm model manufactured by Instant Ocean. How does Coral-life compare?

Thanks,

drew

hey bro hobgoblin, dun mind if i asked and to a certain extend hijack your thread...wat is the refractometer used for again?? and how do u use it?? hav seen some for sale in the pasar malam sections...but hav no idead wat it is used for...can u or any bros out there enlighten me?? thanks..

a refractometer is used to measure the specific gravity of our saltwater through reflective index.

given that light refract at different angle at different medium.

an accurate piece of equipment .

thanks bro!!

but the test uses cheap hydrometer heard that seatest or coral life brand is not bad , any bro here try test with this brand?

coralife deep 6 is good for a floating arm hydrometer. Apparently they are each tested and certified as being accurate to 0.001, which is good enough for me!

That is written on the packaging right?

Just take my comments with a pinch of salt. I just could not help but comment.

so far i use several brands...seatest is the most accurate...

i use seatest and coralife hydrometer.

only during my hypo treatment for my main tank , i use refractometer.

Hi folks,

I agree that a refractometer is the best and most accurate instrument, but I'm tied down by budget. I handled it in an aerospace plant, calibrating it in conjunction with some unknown liquid.

I'm having trouble getting the corallife hydrometer to work. Perhaps I'm not sure how it should be working. Can someone enlighten me?

Thanks,

Actually Guyz;

We do not need accuracy that much for marine, but it is good to have a refractometer as it is so much more convenient to use and slightly less messy.

The floating hygro is the worst as it is simply disturbed by the current/flow in the tank. If no current, it is still accurate. The floating arm hydrometer is good enuf for marine and most cost effective.

Me I use the floating Hygro for 3 years, only last month uses a refractometer, and find it is more convenient.

Yes, and refractometer prices had dropped from the $100+ when it was first introduced to the hobby and I find that it had slowly become a must-have for this hobby.
