Salinity Dropping??

[alrha]

Strange, I've noticed the Salinity on my tank dropping somehow lately.

I keep adding some salt water to the tank (hoping to increase salinity) without removing any water, yet my salinity continues to just drop on its own. I maintain 1.026 SG (53 on my pinpoint monitor). I recalibrated my monitor to make sure it is working correctly, and also double checked it using a hydrometer (to make sure it was not just the electronics of the monitor). My salinity is now at 1.025 (50 on the pinpoint) and i have only added salt water without removing any. My skimmer only removes about 50-100mL / day, and i've been adding about 2-4L/day of salt water. i even scraped the salt creep off my sump and added it back to my tank. i cant figure out where the salt is going...

the only difference i've made is raising my temp from 76-79 over the past couple of weeks, could that impact my salinity?

Any massive amount of salt creep in your system?
I've experienced salinity drops when I installed a pair of computer fans to dissipate heat from my fuge light. Got massive amount of salt creep on the sides of my fuge.

Anything similiar?

Skimming wet while topping off with RO water will also cause a salinity drop.

i did ramp up my fans as well, but as i mentioned, i brushed the salt creep back into the tank.

thanks for the links Mr Google, time to read...

Albert,

I believe 51.3 is the SG for .025 on the pinpoint salinity monitor. I could be wrong.

Also, I would have someone bring over a refractometer to double check.

according to that thread, salinity should INCREASE with temp, i, however experienced a decrase, so it actually is worse than i thought?

you are correct, it swings as low as 50 which is below 1.025, i just wanted to use a round number.

anyone got one?
perhaps i can bring some water to the swap and check it there?

You beat me to it. I am about to ask Deanos, our link guru, to get you another link. This article does not explain your situation. Haha.

EDIT: Deanos can never lose his touch... (watch, now he's gonna come up with some sort of pic showing his "touch") :lol:

uh oh, i hope he's not losing his touch...

he is going to give you wrong links from now on after what you said J/K J/K

i topped off with more salt water than is skimmed (unless the skimmer removes more salt than water - does it?)

My skimmer only removes about 50-100mL / day, and i've been adding about 2-4L/day of salt water.

Airport pick up time-see you guys later.

Really want to find out what's going on in your case because I have a reverse of what you experienced.

 

[alrha]

Deanos doesnt know what he's talking about, i dont know why you trust his links

Now why would you say such a thing?

 

[alrha]

I have a reverse of what you experienced.

the reverse could be do to additives increasing your salinity.

LOL good post editing!!!!:groupflip :biglaugh:

Back to jokes again----See he is not posting any helpful links for us now for a whole day.

could be, still under investigation.

is your top off injecting to much water back in your tank? ,that can cause a prob ,even if its doing a bit at a time ,Check your top off level and make sure it working correcly ,nothing stuck on the floats ,.,.,.,,.,.,
