salinity help

Hello everybody, I have just started my first saltwater tank and am wondering on what is the best salinity tester. I want something that is accurate and easy to use. Preferably under $80. TIA

Hey all. I have a 10 gallon reef tank with LPS corals and a neon cleaner goby. I have a useek nano ATO, which was doing great until yesterday/today. I noticed some coral dieoff, tested all normal params, and they were good. Tested salinity and it was at .015sg. Checked usage on it and noticed...

My usual routine is to run about 30-32 gallons of RODI for my water change, and I mix my salt overnight. I use Red Sea Coral Pro and have never had a problem. I realize instructions say not to mix more than 2 hours, but by aerating it overnight I’ve had better luck with a stable reading. I’ve...

Hi Reefers! I have a 40 gallon breeder tank that has constantly been at 1.025 specific gravity for my salinity and now I am at 1.030. I usually get my pre-mix from a specific LFS, but I was not in the area at the time I needed water so I went to another store that I never used their water. My...

Hello, I am in urgent need of help!!!!! I was treating my QT Tank with Hypo Salinity at 1.09 Salinity to treat what I believe was/is Gill flukes on my orchid dottyback fish that was flashing a lot!! , I had an ATO on and was at about 28 Days at 1.09 Salinity and I noticed my Orchid dottyback...

Hi all, I'm currently in the midst of a bit of confusion in relation to salinity within my tank. I use the Hanna salinity tester and of late, after much neglect, readings in my tank were a little low, around 32.5 ppt. I turned off my ATO in order to bring the salinity back up slowly to give...

Hello All! my tank salinity was low 1.020 and over the period of two days i increased the salinity from 1.020 to 1.022 and then from 1.022 to 1.025. The first change was done by adding extra water and salt but for the second change, i took out water from the aquarium, mixed salt and poured it...

Hello everyone, I really tried to figure this out before making this thread. I also read a few similar threads from other members with similar problems. But decided to make my own thread in the end (hopefully this is in the correct area). I apologize in advance for the long read. Tank is a...

I've been calibrating my refractometer with RODI for the past 2 years. I now know that it's best to calibrate with calibration solution. I want to switch to calibrating with the solution with my next water change, but the problem that I ran into is when I calibrate using the solution my tanks...

Hi all, I have some confusion with measuring salinity. I started a month ago with cycling my tank with a salinity of 1.025 measured with an aquamedic LED refractometer. Last week I found out about the tropic-marin hydrometer so today I bought it for faster salinity measuring. But here's the...

Hi all, recently I upgraded my 55 gallon to a 90 gallon tank. The tank was bought off someone and I got everything up and running yesterday. The tank already came with a good amount of fish in it which I plan to take some out and give to my Lfs. Currently, there are a pair of ocellaris, a coral...

Hi all. I have a 150g DT and a 75g sump (which I maintain at 35g) my DT has three fishes, a couple juvenile Vlamingii and a juvenile Hippo tang. Tank salinity is 1.021. I plan to start reefing in 6 months time so I would like to gradually increase the salinity to 1.023/4 for my fish to get...

I ran random parameters due to upset polyps. My salinity was sitting at 1.017 and I believe I raised it too fast. It's now at 1.023 and I ticked off all my corals. My chalice and candy canes are currently shedding color and slime throughout the tank while all my polpys are closed. I'm worried...

What you guys think on the salinity?

Hi all, Newbie here. I bought a Neptune Apex and installed it in my Reefer 250. Up until now (8 days in) I’ve been using a Hanna Salinity tester and have been getting perfect readings of 1.025 - 1.026. The device has been calibrated twice for certainty. The Apex probe, also calibrated, is...

So a few days ago I got a purple tang looked happy. Two days later dead. My water was fine everything great. So I went to my go to fish store. He tested water and my salinity was 40 ppt. My salinity tester (digital) failed me tested incorrectly... So the tang was shocked so makes sense he...

I purchased a reef tank second hand that was well established. The guy I picked it up from said he didn’t measure salinity because he just always removed exactly 4.5 gallons and replaced exactly 4.5 gallons. He said every time he measured he got inconsistent measurements. Well I see the struggle...
