Strontium Levels in Oceanic Salt mix

Reef Aquarium & Tank Building Forum

Help Support Reef Aquarium & Tank Building Forum:

Ok James I did some tests for ya. I mixed up a new batch of salt for some rock I am curing. I used the oceanic salt this time so I could help you out. That and it was on sale, lol. So I mixed up a 90 gallon batch to a ppm level of 35. let it stand over night and tested for strontium. did 3 tests
1st= 6ppm
2nd=7ppm
3rd= 7ppm.


hope it helps

I have setup a 5.5g nano for testing purposes and started with a known factor of 4ppm of Sr.. As soon as the water clears I will be adding more LR... Hopefully in the mean time Maybe I sparked enough interest with RHF and Salifert to figure out what the Sr levels are in this salt... For now I wont be adding it to the Reef anymore and will just be using my test nano...


James

How did you come up with the known factor of 4ppm?

Thanks Mike
It looks like regular water changes whould take care of the Sr.

Thanks Mike for Running those tests.. I feel a bit better about it... Now I know there is a different area to look in about the coralline...

Donw in the 5.5 gal I know it has a Known Value of 4ppm becuase I dosed 1sp which according to the instructions will raise 10g by 2ppm.. So that came up with 4ppm in the 5g..

Atleast I know there is Sr in the salt LOL.. You are the man Mike Thanks again,
James
 
Yea Don one would assume. Str is taken up really fast by corals and such so it is tough to measure once it is in the tank, thier is also alot unknow about str and its role in our tanks. It also combinds with other elements quickly to Chloride is a big one on that.
I have to admit that I have never seen any study done showing the relationship between Str and corraline algae growth. Man I would love to stop corraline growth in my tank, lol most of the maintence I have to do deal with it. I know alk plays a role in the growth of corraline and have always found that scraping it (attacking it) will cause it to spore and thus grwo more.

AAAAAGGGGHHHH, another S-15 report....everybody run!! ;) If a wide range of salt brand testing is done, lets hope it is by an independent company that doesn't have a vested interest in any of the salts being studied.
i was not going to say anything about the S-15 due to the fact that im an uneducated wannabe internet guru that should be reading a comic book...LOL...thanks Nikki!
 
I wanted to comment on the "impurities" issue. I was reading some information on another site where a salt manufacturer was discussing trace elements. Here is what he had to say.

A dual cone mixer has demonstrated to be incapable of producing a totally homogenous blend of major, minor and trace elements. -- This when all ingredients are added to the mixer at the same time. -- This is why many marine salt manufacturers DO NOT actually add Trace Elements... they rely on the trace impurities found in some grades or purity of major or bulk salts.

I'm not commenting one way nor the other on the accuracy of this statement because I don't know for sure if it's true. It just was interesting that a manufacturer also used the word impurity.

So your guessing the beginning value of the fresh mix is 0 ??
My guess would be the known value without testing would be >4 and <20.

Thanks for posting your test Mike. Don, I believe we are on the same page with regards that the Sr level in the nano would be more than 4. However, it may have been under the assumption that the salt had 0 Sr.....which we now know (at least in Mike's batch) isn't so.
 
on a side note, i went to my other LFS and they finally got Oceanic in and its 200g@$55. im happy with that, i didnt get any though,,,i got a great deal on a 6" electric green Crocea....it just came in and was nipped a bit on the mantle, but i couldnt resist the price. they like me...pics to come soon,,,he is dripping right now.
 
On a Side, Side note

It was mentioned that maybe we should make our own AFSW, well I was thinking about that for some time, but consistency problems still can occur, even though you painstakingly measure the perfect batch each time, the question arises, Is the salt supplier that consistent, how about the trace elements, you have to add those right, can that supplier produce the exacting measures each time, forever? Can any one salt manufacturer make a salt mixture perfectly every time?

I may be way wrong here but the makers of these salts, have a better chance of being more consistent than we could ever be, even though they will have a percentage that will fail tolerances from time to time, I have to believe that if they want to sell their product for any length of time, they will do what it takes to correct the problem, or at least reduce the instances of failures. I know they may not come up front & bring up the fact that there has been problems but look at it from their side on a big scale of things, makes sense to quietly fix the problem & move on as quickly as possible.

I once read that the makes of beer has an allowable amount of contaminants (I.E. bugs, roaches etc per given quantity of beer produced. I also read that somewhere between 90 & 99 % of all chocolate has some pieces of insect in every bite, so considering, I think our salt makers of all kinds do a very good job. Point is, at any given day or time, something can cause major problems, our system are too small to allow for all mal-functions, mistakes etc. Pick a salt, any salt and stick with it, ok maybe not any but you get the idea. In most cases availability & price drives the average bear!

I went with the "known" value of 4ppm because thats what I knew for a fact was in there...

AS for a lighter note.. I have noticed quite a few spots of coralline in my fuge.. It could be coincidence that It just showed up or it could be from the Sr.. Who knows... All I know is its there and thats what counts LOL...

yeah i just had to scrape my front and side walls today to get rid of some coralline and i just did it less than a week ago. when i first set up my tank i couldn't wait for coralline to grow now i wished i could slow it down.
 
Here is what I wish for, I want it to grow like crazy on my rocks and take over the brown fuzzies i have, and never grow on the glass. How the hell do I train my corraline to do that ;)
 
a thought went through my feeble brain last night concerning the Ca levels in oceanic salt. there have been claims of high Ca levels of 500+. and some forks are saying that it is a bad thing. but is it really? when we do water changes we are not doing 100% changes. if we did then our tank levels would then be 500+ Ca and lower alk levels. but when doing what is considered a normal routine change of 5-20% the Ca levels will only go up that percentage. if you have a high Ca demand reef, would bumping your Ca during a change from say 420 to 440 during a change really hurt?

Alkalinity is another thought. the alk of the tank will fall proportionally to the change. but this in my mind is not the end of the world. of things that may need fixing, this is the easiest and least expensive to tweak.

i can see where these ratios can be a concern for a newly set up tank and the new hobbyist doesnt have the expertise to deal with these issues and levels. but for those with a bit of time invested in the hobby is this a major concern? granted a perfect salt would be nice, but hey, you can always get quality cardboard in your salt.

any thoughts?
 
I'm not overly concerned about the high calcium & mag readings as long as everything is balanced. The issue is Oceanic is based everything on a S=30 and not 35, so when we mix our water to S=35, we are seeing the high readings.
 
I hear Habib from Salifert was talking to them about that and suggested they lower it some... They took his suggestion but I have yet to hear if they were actually going to lower it... I guess I could call Oceanic back and see if they have plans too.. LOL
