| I am curious as to what others keep their specific gravity at. Mine is at 1.025. Others, please let me know where your specific gravity or salinity is. |

1.025 per refractometer.
By the way, the swing arm hydrometers are crap. never could get 2 that agreed even to a large margin of error. I bought a high precision floating hydrometer, and then finally refractometer. A must have in my book. The ideas of low salinity being good (1.020 - 1.021) are in my opinion old-school hocus pocus. Do what the ocean does - 1.025 or 1.026 depending on which actual reef you are talking about. ------------- Jim Perry http://www.rockcanyon.com/reef - Jim s reef |

Hi,Jim! Glad to see you're back! Do you think the floating hydrometers are accurate? It's a pain to turn all your pumps off and crap, but I've spent too much $$$$ lately on other crap! Gotta wait for a birthday or Xmas or something...And why do you think it's bad to run salinity low? I want to lower ours a little, 'cause the rotifers like it a little lower.....I'm afraid they will go into shock when I throw 'em in.(Wait, like it matters! They're just instantly scarfed down!) ------------- http://www.suzysreef.com - SuzysReef.com http://z4.invisionfree.com/UtahBreeder/index.php?showtopic=11&st=0&#last - Using Macroalgae for Aquascaping |

Suzy, I use the floating type (Tropic Marin). Just get a piece of 2"pvc or similar and glue a cap on one end. Then just scoop water out of your tank and place the hydrometer in it. This also makes it very easy to read. ------------- Kevin Kunz (Sandy, UT) 300g reef "A trade by which one gains and the other loses is a fraud." Ayn Rand |

| That is too easy! And I've got some pvc in my useless aquarium crap stash! Thanks! Do you think it's pretty accurate? I've actually got one in that same stash....Do you clean it with vinegar or anything? |

I don't know what kind you have but I know mine is very, very accurate. I just wipe mine off with a towel after I test. If you are worried about how accurate yours is then test it against a refractometer and if it is off just adjust your reading. Unlike the swingarm types it should always stay consistant. ------------- Kevin Kunz (Sandy, UT) 300g reef "A trade by which one gains and the other loses is a fraud." Ayn Rand |

Kevin, you don't think the swing-arm type are consistantly off. i.e. that they couldn't just be compared to a refractometer to get a constant difference that is either added or subtracted from the swing-arm reading even at a different salinity?
I have looked all over for a floating hydrometer with a lot of space between the graduations. All that I've seen have about 1/4 - 1/2 inch between 1.020 and 1.030. Is your's wider then that? Floating hydrometers can be very accurate. I won't vouch for the ones sold in fish shops, but we have/use many different sized ones out at work. The largest (at least most popular) manufacture of precision hydrometers is Ertco. If you're using a lab standard hydrometer it's most likely an Ertco and calibrated to 60�F so you must adjust your reading to your tank's temperature. Most that I've seen sold in pet stores are calibrated to 77�F and there is a very slight adjustment from there to say 82�F (may not be worth the bother). ------------- Jon https://www.youtube.com/channel/UC6y_EzjI_ljbIwf2n5uNzTw" rel="nofollow - What I've been doing... |

Jon, I think the hydrometers with a swing arm can be consistant but over time if you don't recheck it it could drift off because of build up on the arm and or pivot point. The glass one I have is a Tropic Marin. It is calibrated at 75 degrees. It is about 15 inches long and the scale goes from 1.018 to 1.028 (I'm just going from memory here so I may be off a little.) The scale is about a half inch between say 1.025 to 1.026 with marks at every 0.0001. I used to have a Lamotte but the kids broke it. The scale on the Tropic Marin is much wider. The only trouble with it is I can't use it to measure hyposalinity. That's what the Lamotte was for. ------------- Kevin Kunz (Sandy, UT) 300g reef "A trade by which one gains and the other loses is a fraud." Ayn Rand |

Thanks Kevin, I'll look for the Tropic Marin (did you find it locally?). ------------- Jon https://www.youtube.com/channel/UC6y_EzjI_ljbIwf2n5uNzTw" rel="nofollow - What I've been doing... |

I actually bought online at Big Als but I noticed awhile back that their price had gone up to about $40. I believe you can get them at www.thatpetplace.com for about $17. ------------- Kevin Kunz (Sandy, UT) 300g reef "A trade by which one gains and the other loses is a fraud." Ayn Rand |
