My salinity was down to 1.019 this morning, I feel like I should just leave this and let evaporation bring it back upto normal, I can't think why it would go down though

The likeliest explanations are either your equipment is mis-reading,  or you have a leak,

1. Equipment- check and double check there are no bubbles on the hydrometer.  If you're using a refractometer check it's calibrated correctly and that the lens is clean.

2. Leak- look for salt stains or crystals around the tank.

Also check with your mods to the filtration system that you are not slowing the flow down at all...as that can cause weird issues with water ending up in the wrong chambers in the sump (then the level in the main tanks looks low, so you top it up thus diluting the salinity).

I have thoroughly checked for leaks and thankfully all was bone dry, I should hope so too with it being a new tank lol, I think I may have mixed last nights water change a little lower than I should have and that's what caused it, I was worried more about adding too much salt so played it safe when really I should have mixed it higher, I will be checking again soon and see if it's changed at all during the day

I think I worded it bad, the salinity was 1.021 last night but 1.019 this morning but I think due to the too weak solution from the water change yesterday, if evaporation hasn't raised it at all today I will drain another 5l and add more saltwater in

Phew, salinity is reading 1.020 so it is slowly climbing to be expected, thankfully, it may just have been a bad reading it is a salinity meter I have, I haven't bought a refractometer yet

Best thing to do is like you say,leave it for 48 hours then check the salinity again then we'll go from there.
Thing is the tank parameters can change daily,so by testing every day can lead to over panic,this is why I do mine weekly ,make a note of what things are,test the following week and compare,then you can make a decision on what needs to be done if anything ,

I definitely know what you mean by panicking by daily testing, thinking back on it I think that contributed to me giving up on my last saltwater tank about 10 years ago, it makes sense they would be different levels throughout a day as waste is produced and treated, I think I'll go 2-3 days between check with it so young but after it's established weekly testing along with waterchanges

I'm sure you'll be ok,a lot has happened in 10 years,for instance I found a few more grey hairs than I did 10 years ago and I could run up a hill without passing out and shouting for oxygen. lol lol lol lol
Plus you have all of us here to help and guide you through any problems now.
We might be all fruit cakes here but when we come together we do make a exceedingly good fruit loaf. lol lol
New decade new friends.

Haha I'm a bit nuts myself mate so we can throw that into the mix lol, I'm glad you are all very patient people because I must be nipping your heads with questions, believe me my head is just as busy lol I'm going in circles a bit with salinity readings, I know I wasn't going to but I couldn't resist testing again to rest my mind and done the opposite as I'm getting a reading of 1.019 again I'm not sure if I can say for definite though as I have checked for leaks, definitely none but my reading is still saying 1.019 after checking a few times now, could it be because I'm using a hydrometer so not as accurate?

 lol lol lol
Here's all you need remember.
1- if you don't ask you don't get.
2- if you don't ask you won't learn.
3- ask as many questions as you like no matter how silly you think it might be.
4- we all started the same way,asking questions ,
The contraption you're using went out with Captain Kirk in to space. It's ok as a guide,but that's all ,you should get a refractometer,that will give you a more precise reading,you Can get them for about £12 on amazon,
And STOP TESTING EVERY 5 Minutes,you'll drive yourself bonkers.
Trust you're instincts and gut feeling,use the force young Jedi ,if that fails you got us morons to fall back on. lol

Rome wasn't built in a day,
Brigadoo wasn't learned in a day,
It took ages for people to work out black pudding doesn't come with custard,
And the reason why scotts don't tell or show you what's under their kilts is because it's so bloody cold up there it takes all day to find it , lol lol
So why would marine keeping be any different,it all takes time, lol lol
But well worth it in the end  8D

Very true words there Dave, I have just ordered an atc led refractometer from ebay just now, £16 posted and supposed rrp of £35 brand new from an eBay shop, I will need to pick up calibration fluid but I hope it will atleast give me more accuracy than that floating needle, so what you saying is I should wait 10mins between testing??? Lol , I know what you mean it definitely is driving me nuts but the truth is my fish looks fine (sleeping now though) and my hermit crab is always on the move, the turbo snails haven't moved much, one did when he first went in but recently they have chilled out, I don't have much algae though I just place them on top of an algae flake until it starts to grow, basically the fish and inverts are alive and seem happy so I am definitely over panicking, I do want to raise the salinity as it probably is a bit low but I know me adding a load of salt in a one litre jug will probably cause more problems than letting it build over a few days with evaporation, at the weekend I can do another water change and mix my water stronger this time round

Wait till you get the refractometer before you add anything,
If you do add a salt mix before let's just say you make up a batch of 1 litre ,add 1/2 of it at a time at 2 hourly intervals wait an hour in between each one,test it to see where you are that way after the 1 st 1/2 you may not need the other 1/2 if you're salinity has come up to where you want it to be ,but around 1020 is good,that's fine.

My refractometer should be here this week so I will wait till then before doing anything, that's a good idea adding slowly over 2 hours rather than all at once, I know 1.020 - 1.026 is good for fish  is 1.020 OK for soft corals? I don't have any yet but definitely want some nice softies once I've got the tank cycled and passed any algae spikes, also does adding soft corals help water quality similar to how plants help in a freshwater tank?
