salinity

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...

So I did a water change but had a little mishap with my ATO staying siphoned on and adding too much freshwater to the system (about another 3 gallons to my 90-ish gallon system). I thought it wouldn’t be a really big deal if I just gave it a few days to evaporate out and get back to the correct...

Hi guys, I’m new to the forum and the hobby. I have two sons who are absolutely obsessed with corals and saltwater fish so finally decided to get one and once looking into the hobby I have fallen in love with it aswell! I just wanted to confirm the weekly water changes are done with salt...

So i have never tested the salinity of the coral tanks at my lfs for over 10 years now thinking the corals will be kept at 1.025-1.026. I would sometimes just drop them in the tank pro problems. Sometimes drip for 30 mins. I know the fish are kept at a low salinity to save money on salt but i...

So I just bought a Hanna salinity checker for my tank. A little reason why I bought the checker. I travel a lot for work and so a lot of the time I’m not home to look after the tank. My family do a good job of the basics and then I do the water changes when I’m home. Recently they needed to do a...

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...

So I have been using the hanna digital salinity checker for my salinity readings for the past year or so and have consistently gotten a reading of 1.023 with an occasional jump to 1.024. I just bought a refractometer and tried it today and got a reading of 1.026. This is a day after getting a...

Hey everyone. I'm curious to see what anyone has to say about the lowest they've seen their salinity in their tank with corals still thriving? I recently realized my tank was running at 1.020 for quite a long period of time. Verified by 2 separate digital Milwaukee checkers. I've since brought...
