Cool, another euphyllia lover! Nice.
Hmm. Turned off actinics for a sec, and the new RFA turned silver where its blue. Fire and Ice? Nah, too cliché. This is definitely my favorite, ironic that I can't get all the colors for the life of me. So cool IRL. I would pay to get a good picture of it.

Ya can't wait to get my 190 up and running again. All those are going in it. I'm in the process of redoing everything under the tank. All new filtration, reactor everything and I'm building it all.
Here is the plan for the sump
Also have these coming next week

Hmm, I'm not too keen on a huge sump. I'll probably just get 2 Eshopps Cubes--just for fun--for my 30 gallon. Assuming they'll fit. It'd be really cool, I think. And overkill... what the heck! And the slanted forefront.

So does this mean salinity is higher in warmer water? Sorta?No worries. It's probably nothing.
One of the only really good looking zoas I own(blue ones) have been messing with me for three days.
I took them out and punched them.
Ignore this till later.
In short, salinity is effected by density. As temperatures change water density changes ( molecules expand retract), and and the salts are basicly squeezed.

Yeah, in essence... higher temperatures basically increase density and pack salt, allowing for more salt to occupy it. Take when you're stirring sugar into coffee. When it's iced, it doesn't dissolve as well, but when it's warmer, they dissolve more. Not the sole reason, but it is a factor.
Lower. the density of seawater (S = 35) changes from 1.028 g/cm3 at 3.98°C to 1.025 g/cm3 at 20°C to 1.023 g/cm3 at a typical marine aquarium temperature of 80°F. Since the density of the sample is changing with temperature, the measured specific gravity will also change, unless this is taken into account.
Also the temperature of the device being used plays a small factor too.
But as I understand it, and as " critical" and "important" as everyone says it is, it's usually just fine unless less the change is drasticly low or high or really fast.
So don't get freaked by minor salinity changes. It can be minor temp changes in water or the tool.
It's much like air pressure in a way. Going from high pressure underwater to the surface gives us the bends. You've heard of fresh water dips for ICK. Kinda the same , it's osmotic shock. Sudden pressure change.
For smalltanks and folks who insist on hard to keep corals in them it's also a factor as sps have thin skin so a thin circulatory system. Add that to alk and other chemistry changes as salinity rises. Hardy fish and corals aren't usually effected too much or when I forget to turn of my ato during a water change and dump two gallons of rodi in my tank I'd be really really ;Vomit It's happened.
