salinity

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...

Hello everyone!! Is it possible to lower alkalinity and raise salinity with Red Sea coral pro that’s known for high ALK. I just bought the bucket and I'm trying to use it all lol before switching. I’m trying to raise my salinity for my torches because I think that might be the problems to why...

Hello all, Weird question. So basically, I’ve always used a bottle of Fritz Refractometer fluid to calibrate my refractometer. I had a bottle of BRS fluid, and also just got another brand new one. Well today I tried all of them, to find there was a difference of 5ppt between the Fritz and a BRS...

I have a Neptune Systems Lab Grade Conductivity/Salinity Probe with 3 calibration fluids. Brand new has not been used or taken out of the box. Can ship out as soon as payment is made. Any questions please let me know!

So I received some fish online. This vendor ships their fish low, around 1.18-1.19 is advertised. I tested the bag water and it was 1.16-1.17. No biggie, adjusted my 10 gallon acclimation tank and after a 30 minute temperature acclimation and dumped just the fish in. Longnose butterfly and...

So I just purchased the new Hanna Marine Monitor that has a PH probe and a Salinity/Temp probe. The unit continuously displays the above and uses temp to accurately calculate it’s readings. I hooked the unit up and followed the instructions on how to use the included 7.1 ph solution satchets and...

What you suggest for a good salinity level? Mine is around 1.025 at the moment

Hi all, I hope youre keeping well. I'm wondering if anyone may be able to help me! So my Neptune salinity Probe consistently reads VERY high (40-60ppt!). Tank is at 35ppt verified by 2 hanna salinity testers a refractometer and a hydrometer. I understand that the neptune probe is conductivity...

I conducted a 50% water change a week ago in my Coral & Invertebrate Quarantine Tank (10 gal Fiji Cube). I have a Neptune Apex in this tank. My salinity prior to the change was 33.75 ppt. I intended to raise it to 34.5 ppt with the change. The water change took approximately 30 minutes and...

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...

Hello, I wonder if using Balling with NaOH as the only/main source of kH increases the water's salinity by the same amount as NaCO2 or NaHCO₃. I guess @Randy Holmes-Farley will be the best to answer :)

Hey there, Somewhere I read that salinity level has an influence on the microbiome. It said that higher levels (above 1.025) limit advantageous bacteria's diversity/ability to reproduce and remain active. There's surely something about it, as one of the best aquarium bacterias product - Microbe...

Just added saltwater to my tank, from my LFS. I’m very new to this and bought this fluval hydrometer. Don’t know if it’s accurate or not, just figured I’d start with this and upgrade later. I’m not sure if this is accurate though. Is this hydrometer not worth a lick? I followed directions and...

Brand new in box, sealed. Asking 600. Will consider trades for new or lightly used G5/G6 XR 15 with Mount + some cash.

I was wondering if there was any Salinity testing equipment that actively reads Salinity in real-time, I use the Hanna Salinity Checker which I really enjoy but sometimes I get the feeling that it's not as accurate as a Refractometer.

I've now had a second ICP returned indicating low sodium and hence low PSU, latest 29.30PSU! Last ICP was 30.70, which ended up scrabbling with multiple refractometers and calibration fuilds making me happy my tank was at 35ppt. Mg and K are at the low end, but Ca is normal. These are were I...

Good afternoon, I’m looking for the best long term choice for salinity readings. I don’t mind paying up to $200 if it means I’m getting as close to “precise” as possible readings because that way I can get closer to point of stability. •Is this the top of the line for refractometers¿ And is...

Good afternoon, Using tropic Marin pro reef mix (German); I have ~25 gallons and added 12 1/2 cups of salt and ended up with 1.010 on my refractometer after 36 hours (heater at 77 and power head in the brute container too) which idk why feels odd. The furniture I was planning to put the tank on...

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...

So finals are looming for me so Ive been swamped with college work the past couple days and haven’t been topping my water off (I know I know ATO). I’ve been testing my water daily this week trying to determine my nutrient intake. With today being day 7 I finally started to see a drop in...

Do you all drip acclimate your acros? Ive always dripped all of my corals but ive heard some say its unnecessary and just stresses them out more. Im starting to rethink dripping. But this new batch of acro (40 min drive) came with a 0.005 salinity difference. So my question is at what salinity...

Have a 75 Gallon mixed reef tank with sump, skimmer, cheato, 2 part dosing. System been running for 3+ years My wife noticed a bunch of empty snail shells at bottom, more then few extra I have for hermit crabs to use. Looking deeper found bunch of snails had died, blastomusto pulled in and not...

So I just went through the huge trouble of making a online probe holder that is on my return pump manifold, the problem is I’m still getting jump readings, it’s off and keeps dropping every hour , is there something I can do to fix this problem? Also does anyone know the max flow than can go...
