Video which compares the Hanna Salinity checker to Tropic Marin Hydrometer. This video is consistent with my experience with Hanna’s salinity checker: Not accurate even when calibrated. Also compares against the Hydros salinity probe: Does not look reliable whatsoever

Milwaukee Salinity Meter Works Perfect Has added case. Leaving Hobby. SOLD

Hello all! Got back into the hobby and Started a new tank yesterday . 20G AIO Waterbox cube . Used about 8lbs of liverock from a local fish store in Rhode Island . Dosed a 4 OZ bottle of Fritz turbostart 900 into the tank yesterday evening and this morning added 3 ML of Dr Tim’s ammonium...

Well I'm finally hitting crossroad with my small nem tank. I got one black widow and 3 rbtas. The 3 rbtas are fine. But the black widow has started to bleach. I wasn't really paying attention I though it was the light intensity since switching from kessil 80 to dalua pixel LED then back to...

Hi there, I recently just started my first tank. It's a Waterbox 25 Peninsula with stock equipment along with a 100w Sicce heater. I filled my tank a little under 48 hours ago and added my live sand about 16 hours ago and plan to add my rock today. I only put the sponges and bio balls in the...

Hey guys, so Im about to have my first tank with a sump, I’ve had a canister filter on a mixed reef for about 5 years and now I’m upgrading. When you get new fish or coral, after acclimation, you top the tank off with salt water correct? I’ve been looking it up and found things that say top...

How significantly do salinity probes drift over time, and how often should they be recalibrated to maintain accurate measurements? I am considering purchasing the Hanna Marine Monitor or perhaps American Marine Salinity Monitor Pinpoint Tester. However, I have been told these can drift and need...

Hello! I have an Excel sheet, where I have a lot of aquarium data, and I have found myself in the need many times to want to know in a direct way how much is in gravity unit the value obtained from a measurement of a Hanna pencil (for example) in ppt. And the other way around too, to have the...

New to Reef2Reef, and hope this is allowed. I am having salinity issues after being in the hobby for about a year now. My refractometer’s (new and old) are reading wonky. And I have calibrated with 35ppt solution from BRS and AccuraSea, different readings from Both and NOT 35 ppt. I am...

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...

I bought this set a few years ago and used one time. These are in brand new condition. The reagents have expired. I would like to trade do zoas, mushrooms, torches, hammers or any soft coral that gets my attention.

I’ve got 3 separate tools to measure salinity. A Red Sea refractometer that I keep having to calibrate, and 2 different swing arms that I’ve had forever. I recently went ahead and recalibrated the Red Sea with some solution I purchased on Amazon (continuum reagents at 1.026). Unfortunately, my...

My tank is redsea S1000 G2+ and is 6 months old. From the start, i coukd never get Salinity up to 35. The maximum it went up to according to my well-calibrated Hanna tester was 32. I've done many water replacements with well salt-mixed RO water.. sometimes 10 percent sometimes upto 40% and...

Selling my rarely used Hanna checkers.. salinity tester. Calibration solution good until 2028 $50 shipped Alkalinity tester with open reagent more than 50% left . Good until March 2025 $40 shipped Take both for $80 shipped

Hi all For the past couple years I’ve only been using my good old refractometer and calibrating it with 35ppt solution to measure my salinity in tanks and when mixing water. It has always worked well for me and is my standard for mixing water. Well recently I purchased the Hanna marine...

Excellent condition, used for about a year for water change testing. $65 shipped.

Hello fellow reefers! I am looking at a gravity fed ATO for my 140 going into a float valve. Is there a reason why people don’t put the ATO on a slow drip with a quarter turn valve? It is something that could be dialed in and adjusted for seasonal changes? I feel like it would be more...

Hi all, I'm currently struggling with some parameter issues. I've attached at the bottom what my levels are as of this past Saturday and a video of my tank. Right now I'm slowly trying to raise my salinity by topping off with 1.026. My pH has be stable at 8 for about two months. My nitrate...

Anyone know why I am getting 1.030 salinity from Instant Ocean Reef Crystals? I'm mixing up two gallons for my water change tomorrow and just tested the salinity and I don't understand how it's so high. Regardless I'm trying to raise my salinity, it dropped to 1.023, would I be fine to do a...

Hi, I have a pair of clownfish in a 105l tank. The tank is just over a year old now. Water parameters are as follows Salinity - 1.0275 [Red Sea Coral Pro Salt salt + RODI water]. My ATO malfunctioned, and I am slowly bringing this down. pH - 7.75 Ammonia - 0ppm (Salifert test kit) +...

What level do you keep your salinity at

Like new Hanna salinity tester less then half a year old . Works great 50 shipped

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...
