ESV Salt Ratio's

Maybe this is what ESV was talking about? As far as not changing their values??? With reliable test kits it's okay, yeah?

I think the concern is with the many other things that you do not or cannot measure being artificially high or low, albeit by a small amount. Borate, iron, iodine, potassium, manganese, vanadium, etc.
 
OK. This is what I got and I am trying to keep the ratio's at the same level as ESV states at 34ppt:

Salinity 1.0264/35ppt
CA=440
ALK=9.24
MG=1380

This is what was used:
Approx Water=5.25g
Sodium Chloride=1 3/4cup
Magnesium Sulfate=5/8cup
Part A=199ml
Part B=100ml

ESV states 1.0255/34ppt at
CA=450
ALK=9.1
MG=1400

I think it's pretty close to what I got so I think I'll be ok. Hopefully.

What esv needs to do is come out with a lower alkalinity calcium salt like red sea blue bucket. Are you listening bob?? Lol.

Is this something you would worry about? This is the one salt I've been able to get the desired Sg, Mg, Ca, and Alk out of (NSW levels).

I'm sure you've already seen the waterchange log above as an example. But, I'm adding about 4.5 - 5.0g more than they recommend / Gallon of NaCl, about 5g more than they recommend / Gallon of MgSO4, about 4g less than they recommend / Gallon of Component A (Ca), and about 2.5 - 3.0g less than they recommend / Gallon of Component B (Alk).
 
I personally wouldn't worry about changes of 5% or less. 10% starts to be more of a concern if it is shorting something significant, such as potassium.
 
Okay. I think I will only be able to keep NaCl <5% change (~4%). MgSO4 is at ~8% more, A is at ~8% less, and B is at 9.0-9.5% less. I will see what the tests say during my next waterchange, to see if they're within acceptable NSW levels. Thanks for the help Randy, it's nice to be able to bounce this stuff off of someone with such knowledge.
 
Why do the salt manufact consistently make alk ca salt that's too strong compared to natural sea water. ?? Are there more people who keep kh up there in 10 11 range?? I mean esv is the king of 2 part for dosing so I can't beleive they want to encourage the water change and replace method instead of dosing??

I expect a part of the reason is that people with FO tanks or those who do not frequently supplement calcium and alkalinity dominate the overall market. For those people, higher levels may be desirable because it helps keep the tank closer to NSW after water changes. :)
 
Is it not possible to mix this with reduced ALK level? I understand the point is to have a consistent mix every time, but also thought you could tweak it a little bit.

No problem. First off I've attached the ESV Chart.. I don't keep it by the comp so maybe this will save you a step as well.

So, I dose about 14.2 grams of component B (alk) / gallon (instead of 21g/gallon). This should give you about 7.0 - 7.5 dKH alkalinity. I've read that all other components should be able to stay relatively the same.. But, recently I found out (through correcting previous calibration errors from my refractometer and now using a pinpoint salinity monitor) that my salinity was coming out to about 31ppt salinity with this procedure.. I've had to add extra NaCl to achieve my desired 35ppt/53.0mS. The strange thing is, and this is where I'm confused - is that others trying to achieve low alk batches like ourselves have said that all they need to do is basically reduce component B (alk) and all other params (including salinity) stay in a desirable range (natural seawater levels). I'm wondering if this an off batch of NaCl for me, or if infact lowering component B this much requires extra NaCl supplement...?

Through your google searches, if you find any of my results pre July 2014 ignore them. Unfortunately, I posted some of my results here and in the zeovit forums before I figured out my refractometer errors, which basically washes their credibility imo.

Thanks, that's helpful! I know component A could affect more than just Ca so I wanted to make sure there wasn't more to consider. I'm glad you mentioned your issue; I'll test it out tomorrow and see if I have a salinity drop and confirm alk level.
 
Not a problem, I'm actually very happy that this thread popped up in my subscriptions again. Please post your results here if you don't mind.
