swing arm hydrometers

    hey folks, ok, so after todays trip around town to get RO/salt water because my LFS 2 miles from my house decided to not have any, and then tell me that they can put me on their waiting list for tomorrow, I've decided that I think I want to mix my own.. SO!!! I know this, I use as directed, wait...

    Hi, my sg reading is just around 1.025, which i have read is very low. We should target 1.027 right? How do I increase salinity without causing damage to the inverts and corals? Please advice. thanks.

    I'm looking into some stuff to suggest we carry at work for products, we have mostly API and Wardley stuff.... we have no reef additives, no salt water meds, and we don't have a line of SW foods other than Sally's Frozen (which is great stuff).... I was hoping to pick some brains and get...

    is there any way i can check my hydrometer against a solution that is right on? without going somewhere to find a refractometer...(ex...mix a solution to exactly 1.025 and check my hydrometer, but how would i know the solution is 1.025?)

    I cannot hardly believe this.. I have two of the Deep Six Hydrometers and a refractometer. if these things are really this far off I cannot beleive they are even allowed to sell the Deep six.:doh: my Deep six says 1.021 my refractometer says 1.026 is this really true? my refractometer came...

    We are needing to make a DIY auto top off as well as a DIY power panel or box. I saw on the computer somewhere where someone had made one in a box and had the instructions and diagram. If you have something or know where we can look just let us know. Thanks,

    I know this has been discussed here before, but I just wanted to say how innacuate swing arm hydrometers are!! Yesterday my RHS-10 ATC refractometer came in :blob: (the same as this http://fishtanksdirect.com/index.asp?PageAction=VIEWPROD&ProdID=9 ) and I checked my tank, WOW was my salinity...

    OK OK I know I could find this out on my own, But what would you guys get out of it? Can you measure salinity with a hydrometer listed for measuring sucrose? Or are they two totally different hydrometers?

    I am new to saltwater tanks, but I know some stuff about them like (Crush Coral, P.H, Temp and etc). Right Now I have a Freshwater aquarium. My Question is, what size tank should I start out with for being a beginner of saltwater and what type of protein skimmer will I need? Thank You<O:p Chris86

    Well, I finally got my refractometer and tested several different sets of water with both the hydrometer and refractometer. The results: DI water @ 1ppm tds Hydrometer: no indication/0 Refractometer: 0 Nano tank(5.5 gal total vol): Hydrometer: 1.025 Refractometer: 1.030 Main tank(65 gal...

    Yesterday I filled my tank up and poured the corrrect amount of salt in the tank. I also had sand in the tank. The water became cloudy and still is. Today I tested the salinity of the tank and got some very weird results. I am using an oceanic salinity tester. I fill this plastic thing up...

    Ok SO the last few weeks has kind of been a mini hell for my tank. 1st about 2 weeks ago I went up north and my anemone got his foot stuck in the power head. He is about the size of a fast-pitch baseball and all of his orange foot almost up to the back part of his oral disk managed to get into...

    I just got a pinpoint salinity monitor today. Just calibrated it, new battery. And it reads a S.G. of 1.0317! Who knows how long it has been that high. My hydrometer has been reading 1.0235 all along, not temperature corrected. Everything in the tank is fine. Could they be used to it...

    I placed an order for some zoos at Aquaprop last night when they added a bunch of new stuff and didn't realize they were running a shipping special. Alot of the best stuff is gone but take a look. Prices are very reasonable. Aquaprop.com

    I recently bought a Coral Life Deep Six Hydrometer which takes readings six inches deep... now the reading I got was about 1.024, but the readings I would get when using the float type salinity meter were 1.022 I wonder if the six inches makes the difference of if the hydrometer from Coral Life...

    For those of you interested in this, I'm curious as to whether anyone has tested the s.g. of ro/di water. I was told long ago that it should test at exactly 1.000 Can anybody confirm this? - it's any easy way to test/calibrate hydrometers if it's true... :)
