well your not gonna drop a full bucket of salt in there right? just a cup or two

your not that low , i keep my tank at 1.022 consitently.

i would put a cup in and see what it does if it doesnt do much then do another etc.

your remaining fish and inverts wont mind a small spike in salinity its not like going from hypo, your just a little low.

It will take 18.5 cups of salt to bring the tank up to 1.026 or 35ppt. How long should I spread that over? 2 hours, 3hrs, 6 hours, 5 days...

well 2hrs im sure is a bad idea , 3 hrs is a bad idea , 4 hrs is a bad idea , 5 hrs is a bad idea etc.

how often do you top off your tank once a day once every two days......never?


play it smart and slow , theres no need to dump 18.5 cups into your tank at once do it over a few days and youll be fine

good luck buddy your thinking in to this to much just raise it slowly like i said a cup or two in your top off water

It should not take 18.5 cups. Your calculations must be wrong.

1/2 cup per gallon gives approx 1.025.

Maybe I'm wrong but that seems way far off.

I'm going by http://www.hamzasreef.com/Contents/C...Calculator.php with 90 gallons water volume

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.

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.
