Question about ESV and it’s uniformity.

[reefiniteasy]

This is probably a dumb question. I buy the two gallon kit of ESV B-Ionic 2-part. I’m thinking of picking up two 2 liter dosing containers. Is ESV 2-part a uniform solution? If all the liquid of each gallon jug doesn’t fit in the dosing container, is that ok? I’m not going to get less of some elements because I’m not dosing from the whole jug, am I? I feel like I should know this, but I’m unsure of my thinking.

I initially bought the smaller 946ml bottles .
My last purchase was the gallon jugs of each cal and alk .
After mixed because they’re concentrated .
shaken and all dissolved I keep filling the smaller bottles .
easier for dosing when needed

I think that answers my question. Thank you!

Yes, all fully dissolved liquid solutions that reefers use are uniform. Ions do not "settle" once dissolved.

Thanks Randy! As always, I appreciate it.

Thanks Randy! As always, I appreciate it.

You're welcome.

Happy reefing.

Follow up to this and slightly on a different tack:

Does temperature affect solubility and concentration?

The gallon jugs I received, especially the part 2(alk) has precipitated in its concentrated state.

Case in point: my reservoir 1000ml containers will be in the basement where the temp is usually always in the range of 40-60°F. The directions state to heat the mixed(conc + rodi) and soak in 100ish temp water to allow for complete solubility.

Since the end product (mixed) is in a cool environment even in the summer, basement is always the coolest, will it precipitate again with the temperature difference?

The alk part will precipitate when cold and redissolve when warm.

If the local temp is too low, just dilute it more and it will be fine.
