salinity

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...

If I test my freshwater bucket for PH before adding salt to raise salinity and adjust to a desired PH, then add my salt. Would I be doing the wrong thing? like how much would salinity change my PH?

I believe I have prazi resistant flukes in my tank...Wondering how to eradicate them and a method of treatment. How would I go about quarantining fish in hypo salinity? I have a good idea on how to do it, but I just want to make sure I do it correctly. My Display is at 1.026 SG And I have 1 10...

Hi all, I bought a GHL Profilux around July. After a tedious installation process, I start getting measurements for Salinity, Temperature, PH and ORP. Salinity was spot on around 35ppt, also matching with my D&D refractometer. But then it started drifting to 34 ppt and stabilized around...

Hey! Finally got a new refractometer. I calibrated it using distilled water and took a reading of the tank. 1.033! Usually the tank runs around 1.026 although lately it’s been closer to 1.024 Recent changes: I moved houses and changed 50% of the water in the 29gals I upgraded within two weeks...

Which is a better overall salinity for fish, 1.024 or 1.026 and why?

I usually sit a 25W heater, an air pump with air-stone and a 1000Lph pump in a 5 gallon bucket, I put in around 700g of salt with 18Liters + or - and usually come back around the same time the next day to do a water change. Would there be anything wrong with using an external heater to heat the...

I have a 125g aquarium, with a fluval fx4. It has a carbon filter, some filter floss(mostly for catching the diatoms), and seachem matrix media. I have a Coralife 125g protein skimmer that still has microbubbles for about a month now and it is pretty loud, but does produce skimmate. I have some...

Hey all, Ive been slowly piecing together my tank, and I’ve spent the past few weeks deciding on what salt to use. I’m currently hung up between Red Sea Salt, or their Coral Pro salt. I live in Australia so some other salts are unavailable, but for my tank needs the coral pro seems best I’ll...

I want to get into the habit of checking my salinity more often. The issue is using a salinity measuring tool that I can trust, and rely on without having to tinker with it every time. An analog refractometer requires quite a bit of tinkering and cleaning for one measurement. The Hanna Salinity...

Hello! I will be going away on vacation in around two weeks for 10 days and I'm considering getting an auto top off system to control the salinity while I'm gone. But there's a catch! My return pump is set to pulse mode and the sump water level changes. Will an auto top system work in my sump...

We are pleased to officially announce the newest product from Vivid Creative Aquatics - the Salinity Probe Stability Kit, or SPS Kit for short. Roughly half of those currently running a Conductivity probe to monitor salinity are having issues with sporadic readings and unreliable results. The...

I have tried The Hannah salinity tester (actually I have 2 of them), the brs refractometer, my lfs refractometer. I can't find a tool that makes me feel 100% confident in my salinity. The drift that I have from my Hannah is absurd. After 3 days of use and another calibration my salinity was...

Hi everyone, I'm totally new to this and I have my tank (46 gal) in its 2nd week of water cycle. My salinity measure was 1127 2 weeks ago and now it reaches 1131. However, the algae is still growing according to the instructions/guide I read. Is it necessary to lower the salinity and how should...

Okay so Hanna's Digital Salinity Meter requires calibration right? Could Hanna produce a Checker that did not require the purchase of calibration solutions? For example if a Salt Mix Pack says "Mix 1g of salt to 1 liter of water for 35ppt" Bearing in mind Hanna Calibration solution is 35ppt, you...

I have 16g biocube. Last week (Thursday) I did about a 15% water change. It was the first water change since adding livestock. I have (had) one oscellaris clown, one trochus snail, and a zoa frag. As I was performing my water change, all was well. About an hour after I finished, my clown went...

In my 65G Reef tank recently added UV Sterilizer which has increased temp by a degree. Also, 2 return pumps, a Reactor pump, UV pump, and Skimmer also are contributing to the heat in the tank. I was maintaining my tank temperatures at 77-78F before adding a UV Sterilizer. To cool down the tank...

Hi all, I bought but never used, $20 shipped to 48 states. 25-Pack HI70024P 35ppt Salinity Calibration Sachet - Hanna Instruments

Hi i'm new to reef2reef so i dont really know how tags work, but I do have a few questions, the biggest being how ro/di water works. Today I recieved an aquaticlife ro/di, and when I tested the hardness (my tap water is beyond unsafe due to it) in which it came out to 0 for the first time ever...

Hello Where can I buy tropic marin hydrometer?

I’ve been reefing for over a year now and just got my first ATO system. I have a 10 gallon mixed reef tank and I would top off around 16-20oz of water a day due to evaporation. My question is, prior to setting up my ATO, what other parameters were likely effected by the salinity swings between...

I recently installed a heater. Never had one before, living in hot south Florida, never really needed one, but I decided to add one to keep temps a little bit warmed in the house with air conditioning. I have been check the temps today and I noticed that my salinity kinda follows it. I know salt...

Hi guys, Back in the hobby after a seriously long hiatus - so practically a noob now. Have a question on using NSW for my pico. (It's a 5g Fluval evo that I perform a 90% water change on weekly) The natural sea water I collect here in Nassau has a salanity of about 1.028 - 1.029 when I...

Hi Guys, Ive kept freshwater and marine tanks before, going to try my hand at a brackish one now. In your experience, what is the minimum salinity in which a protein skimmer becomes effective? Thanks.

I, like many others, have had issues with the conductivity probe from Neptune Apex. When I had the Profilux 4, it's probe nicely matched my two Hanna conductivity probes. After switching to the Neptune realm, I never was able to get included probe to calibrate. I purchased another on the off...
