Help! Salinity drop

[hunggi74]

Don't forget those figures are for making saltwater from regular water. You are adding to your existing water so it would be far less salt needed.

Correct me if I'm wrong, but shouldn't the "current salinity" field compensate for that?

You would think so. To be honest I've never used that calculator but when I entered my numbers for my tank and target salinity it calculated that I needed 22 pounds of salt required. Way too much. Maybe try another calculator? Just seems off to need that much salt.

why don't u just use a refractometer or a salinity tester? This seems like its becoming way more complicated than it needs to be. Add a cup…..wait….test…if to low still add a cup…..wait…..test. So on and so on until you reach your level. Bringing it up from .017 to .023 is not that big of a deal.

+1. I may play a little fast and loose with my salinity, but sometimes if I haven't done a water change in a while and I've been really wet skimming, my salinity can drop to 1.023. My solution: dump an entire cup of salt directly in to the largest chamber of my sump, let it dissolve, test salinity, and if it's not where I want it, dump in a cup more.

Keep in mind that the total volume is 375 gallons so in a smaller volume of water I'd put in a smaller initial amount of salt, but if you add it to your sump far-ish from your return pump, I doubt you'll have problems.

That happened to me as my float stuck for my auto top off and flooded my tank over the top. The salinity was in the same range as you. I just did a couple water changes of hypo salinity water and she was good to go. None of my corals or inverts were affected. I did the water changes maybe 2 hours apart from eachother (because I couldn't make the water fast enough..lol).

Simple answer.

So your salinity is alittle low1.017 to raise it up to 1.024 I would add half a cup of salt to 1liter of your tank water and mix it up then use an air line hose and let it siphon in. Should take 2 min, or just dump in a cup of the premixed saltwater every 5 mins.

I like this idea, snails are actualy quite resiliant as they will pull inside the shell and aclimatize themselves most of the time. I would do like sugested maybe I would go a little harder 1 cup of salt desolved in a L of your water and add it over 10 min. wait a hour and see how much it changed then you know how much you have to add, leep adding every hour till it is normal.

if you want to be more cautious then go with the recomended 1/2 cup of salt.

I know on my system (120 gal of water) i have brought it up with 3 cups of salt an hour mixed into the sump with no issues.
