salinity

TL;DR: Can I mix up Balling Part C such that it has a 1350 Mg and 400 K when diluting for salinity increases and only use when I dilute the tank (rather than dose it daily)? I have a 20g nano mixed reef that is about a year old. The frags are becoming small colonies now, along with coralline...

Hi, I have a few LPS in my tank, but recently my sanity levels fallen below the one I would like it to be. Currently 32-33%o ideally I would like to increase it to higher. Two questions here how high? How would you do it. Water changes doesn't seems to efficient. The tank is LPS dominated...

I have just bought some brightwell calibration fluid for my refractometer, I use to use acurasea but I couldn't get more of that. With acurasea it said my tank was always at 1.025 salinity but now I have calibrated with brightwell it says I am well under that. This is what it reads with the new...

I have a Large FOWLR tank and wanted to know how quick can I raise my salinity? I normally use the 30 mins for every .001 when I acclimate fish that are .002ish off but I would be raising it from 1.011 back to 1.024. I want to run Hypo on my tank because I have a concert that there might be...

The one and only Milwaukee MA887 Salinity Refractometer! This ships with the clam shell case and fresh battery. In fantastic working condition, I am only selling this unit because I already have one. Otherwise I wouldn't give one up for the world. Clam shell case has some scuffs but both it and...

Hey I need to do hypo-salinity on the FOWLR and I wanted to know if my Horn Shark would be able to handle the lower salinity 1.009 for about a week. Some articles say it would be okay but some articles say it won't work for them based of there osmotic pressure inside and how they defuse the...

So it’s my first time cycling a tank and the first few days my salinity was at .025ppm but then on the fourth day it went down to .022ppm I read about salinity going up but not going down. I checked again today and it’s back up to .026ppm. So my question is if it’s normal for salinity to change...

My salinity is rising slowly rising and I don’t have an RODI system. I do have an RO system that I drink from but I was told that RODI is better for the fish. Any ideas what water I could use to top off my tank? (my RO has a TDS of <30).

I rejoined the hobby back ~2016, and everyone seemed to agree that 1.025 was the perfect salinity. Lately though, more and more I've been hearing that 35 ppt is what you should target for mixed reef or SPS dom. It's strange to me that these are often used interchangeably, since 1.025 is really...

I made the rookie mistake of calibrating my refractometer using RODI, checked against LFS water to confirm no egregious slope errors. Refractometer is the red sea unit. I've been reading up on it and seeing that it's incredibly finicky and prone to giving vastly different readings on the same...

In Short: I have salinity at 45+ ppt. How can quickly can I take it down to 35? Should I be water changing with RODI water or low salinity water. In Long: I have been running a reef tank for around 5 months now. It's a reefer 250 (55g). Over time I have gradually tried to add corals. With a few...

Hey all, New poster here. Wanting some opinions. I have a 20g (L) tank, currently running as a fish only set-up but I’m in the process of prepping for coral. This is a tank transfer from my other three year old 20g that sadly sprung a leak, which was a transfer from my first tank, a thriving...

I have been trying to cure some very fresh very live rock I obtained. I set it up at the right temperature and salinity and prepared for the bad smell. It never happened. Every once a while I topped off the tub with RODI. Several weeks ago, i added a shrimp and did 50% water change. It has...

Situation up front, do to my poor selection in refractometers my 90 gal LPS dominate tank is currently sitting at 1.017 and I need to know how much and how quickly I should raise the salinity. I notice that about 2 weeks ago that my hammer wasn’t extending as much as he had been so I started...

Hi Everyone, I have seen a couple posts here. I got my water at my LFS store and it looks like the salinity of the water is running at about 1.03.. Should I try to get that number down? As well I do have the diatoms process.. Since this process has started should I be looking to get a cleaning...

Hello Everyone! So a week ago I realized my ATC refractometer was calibrated wrong by about .003. No big whoop, instead of being at 1.025 my tank was at 1.021 where it was running stable. I did a PWC of about 30%, brought the water up to 1.022 and figured I would just do some manual saltwater...

Hello Everybody, My tank is 2 and half year old and is a 32g biocube. I have a kessil 160WE, ATO, heater, circulation pump and hammers, Lepto, FrogSpwan, Acans, Toadstool. Some scarlet hermit crabs and some snails. The tank is clean minimal algae growth, I do water change every two weeks with...

Hi all, I've started using a Neptune DOS for a daily auto water change. Once a week mix 60 ltr (13 gallons) in my storage tank and leave it to run - so far working well. I have a small powerhead in the storage tank to mix and keep things moving. Typically the water sits around 68' room...

Came across this article and was wondering who else runs their salinity high. https://www.int-res.com/articles/meps/181/m181p309.pdf

A lot of synthetic salt companies recommend different salinity levels for different tank types e.g. fish only is 30 ppt and reef is 35 ppt. My question is: Do they recommend 35 ppt because of the increased micro and macro element levels at that salinity? Or because the corals need a salt level...

For ORP I found this - https://www.bulkreefsupply.com/pinpoint-orp-redox-400-calibration-fluid.html I assume it will work - even though it is not a Neptune specific product? For Salinity I know this will work -...

hey guys, so im planning of setting up a QT tank and trying the Hypo salinity method of killing ich supposedly its the easiest yet the safest way without using copper.... well i have a refactometer that i purchased from petco a year ago and ive been using it to measure my salinity in my current...

I know...I have a problem. I was organizing my supply cabinet and realized I have clearly accumulated more test kits than should ever be necessary. BUT it has been helpful having everything I need at arms reach, and the ease of use of these kits has caused me to test consistently, which I’m...

Ok so in my nano I have a pump pumping water into a refgium and than it over flows back into the tank. The pump failed and the refugium had a salinity of 1.036 by the time I noticed. I keep a zebra hermit in it to both survived and don’t seem stressed. The crab is there to help prevent algae...
