salinity

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...

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) +...

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...

I conducted a 20% water change (on a 10 gal Fiji cube) and removed all of my Neptune Apex probes and cleaned/scrubbed them with a dilute citric acid bath. They then remained in RODI water for a couple of days while I did some other work on my tank. Upon putting them back into service the ORP...

I was thinking of buying a 1000L water tank that could fit on my trailer. I've been doing a lot of fishing with friends recently and have started to notice that as the tide is coming to its highest point, the water is much clearer, especially the closer I get to open Sea as opposed to a Bay. I...

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...
