i had both and the deep6 was about .010 off and the IO was about .020 off. i guess it depends how you calibrate them. and clean them every time you use them. id say get a refractometer

I would skip both of them and go with a refractometer, you can find them for about $40. You will be much happier in the long run and they are far more accurate.

Most certainly get a refractometer, ESPECIALLY for a small tank. The parameters fluctuate so easily in nanos anyway, you don't want an instrument that is off. Way back when, I had a deep six. I was so meticulous about keeping my tank at 1.026. I bought a refractometer and found out that it was actually at 1.031. That was my 55. Get a refractometer.

Yes I think I will invest in one for sure. Just borrowed a friends tonight and wow my salinity is 1.031.....

Holly crap I have my work cut out for me. I will lower it slowly over the day tomorrow. I like it to be 1.025 is that okay??
Gosh they are sure neat things to have for sure. Will have to look for a good deal on one as they are dear in price here in Canada.

Yeah, that is about right. Hydrometers can be off by any degree, as you see from what other's have posted.
1.025 is just fine.
Can you have one shipped online? I don't know the international rules, forgive me.
