Why does reef crystals only have 320 Ca?

The numbers you get are not important to those with low numbers, Billy. Or high ones for that matter. Yours is not the final word. Whatever you may think.

Obviously with all the people that posted in this thread there is a problem with consistency.

Mike, I'm afraid I disagree.

You say "all the people that posted in this thread" Just how many is that ?

And how many is that compared to the thousands of people on Reef Central that are using Reef Crystals and not having problems ?

I spend a lot of my time and money trying to help fellow reefers figure out chemical issues with products and testing supplies. I do this because I enjoy helping out and for as much water testing I have done over the years, I'd like to think the numbers I post are pretty close to real.

Threads like this come along all the time and in many cases, the issue is with testing of some sort and not the actual product itself.

In the 8 years I've been here, I can only remember one salt manufacturing issue and that was the low alk Seachem fiasco awhile back.

I hope you didn't take Boomers recent comments about me seriously. I have no affiliation with Marineland and I do not own stock in Reef Crystals. He was joking with me, as he does from time to time. We are friends.

I simply want to see this for myself since a number of people are seeing problems and it all seems to be coming from the same place, I'm hoping to shed some light on the situation. I am not satisfied with the response one of our members got from Drs Foster & Smith.

Whether you choose to believe my findings or not is up to you. I'm quite sure a number of our members are interested in what I come up with.

Personally, I did not care for your comment or bdare's for that matter. You seem to have been jumping on a number of my posts as of late.

Just because a few people reported a calcium problem with a salt mix doesn't necessarily mean that salt mix has consistency issues. It very well could be a bad batch problem, or a moisture problem, or a mixing problem or a testing problem. I prefer to find the real cause of the problem before we all go and point fingers and accuse manufacturers of a bad product. This has happened too many times in the past in our hobby.

Are you doing anything to help figure out this problem ? If not, I suggest you post in a thread where you can be of some help. :)
 
Hip check hard into the boards! Ouch!

Bill, I look forward to see what you come up with when you get your DFS shipment.

I think the problem here is you are attempting to tell those of us with low number either we are crazy or just don't know how to test water. I've been doing this for a long time. The Ca in the Reef Crystals I have is 360. PERIOD.

Just because you order a bucket from the good Drs and you test your water at 420 isn't going to prove anything. I'm sure they get new salt in all the time. Unless you test the salt from someone who is reporting the low numbers you are simply reporting the results from YOUR bucket.

I'll gladly send you 1/2 cup of salt for you to test.

The reason people are jumping all over you is because as I stated before... you are either telling us we are crazy or incapable of testing our water.

That would be 15

Not many, but that does not matter. How many of them actually test anyway ?

I don't doubt you

]I agree, but that's not always the problem. Many of us have done all we could to ensure accurate results. Like correctly calibrating our refractometers and using multiple test kits

No, not that it would matter to me.

I want that too. That's my point. But IMO it's not really their problem. I'm sure they ship out a lot of buckets. They are just trying to keep their customers satisfied by replacing the buckets.

Whether you choose to believe my findings or not is up to you. I'm quite sure a number of our members are interested in what I come up with.
I totally believe you. I credit the members of this particular forum with enough smarts to use a test kit correctly. How your findings make ours wrong is where I don't agree.

Personally, I did not care for your comment or bdare's for that matter. You seem to have been jumping on a number of my posts as of late.
In this thread, yes. Elswhere, I don't believe I did anything.

Just because a few people reported a calcium problem with a salt mix doesn't necessarily mean that salt mix has consistency issues. It very well could be a bad batch problem, or a moisture problem, or a mixing problem or a testing problem.

If we though it was a bad product, we wouldn't be using it. IMO a bad batch is a consistiency problem. We get thing done in this hobby by threads like this. These forums are R&D for companies like Marineland.

Are you doing anything to help figure out this problem ? If not, I suggest you post in a thread where you can be of some help. :)
Yep, I tell who I can to test their makeup water before adding it to the tank and adjust it as necissary.

I will bet your swing arm is off. You are likely mixing at a lower s.g. than you think, causing the low calcium reading.

I tested a new batch of RC just the other day and at 1.0264 (35 ppt) it registered 420ppm calcium. As it always does.

Those of you seeing other readings are either mixing wrong or have faulty test kits IMO.

I appreciate everyones input here. I'd hope that everyone's Ca and Alk posted readings would be properly considered, as this is just a public forum.

Personally, I don't think one person is enough proof that numerous posted measurements are erroneous, even if it's a possibility. I agree with Billybeau1 & others, that this should be properly evaluated to find out what's been happening.

I doubt there is a conspiracy against the salt mfr going on here.
 
An open mind is best for scientific discovery. Better than ego's or dogma. Perhaps even better with a touch of humility.

Well I'm not going to publicly squabble about your reply although I disagree with a number of your replies. I just found your quote above a jab. I know of no one on Reef Central that thinks anyones post is the "final word" on anything in this hobby. Not even Randy's and I'm sure he'll agree to that. I merely test a lot and post my results.

As you know, testing saltwater has a lot of variables, especially with hobby grade test kits and it is easy to get confused about test results at times.

When you have time, re-read the whole thread from start to finish. Then evaluate your comments. I did that about an hour ago and I see a comment I made that could possibly be construed as offensive. Not my intent or never will it be. Sometimes when threads get real long like this, we tend to loose focus on the original posters question.

We'll get to the bottom of this, collectively , I'm sure. Thats what makes this the best Reef Chemistry forum on the web. :)

Well first off, people aren't jumping all over me as you state. What people ? 2 people ?

Sending me a sample of your salt is useless. You should know that.

Unless I have a bad memory, I don't recall calling anyone crazy for posting their test results. There are many reasons for not seeing expected results from a salt mix. Not just user error.

We deal with all levels of aquarists on this forum and I have no idea what level of experience they have. Sometimes you have to ask the obvious questions to get the simple answers. My intent is not to make them look foolish. My intent is to help them solve their problem. When dealing with water chemistry, many of us assume the reefer has the proper knowledge to deal with these issues. Believe me, many times, this is not the case.

I suspect you need to spend a little more time around here reading threads to understand what I'm talking about.

All right, let's leave the squabbling to some other channel. This forum is for chemistry questions.

I agree

IMHO, the best investigators ask questions when presented with odd looking data. The worst investigators make immediate judgements.

If anyone has other numbers to post, please do. If people want to send me samples of their salt, I'd be willing to do a standardized testing. Of course, we could have more than one person do standardized tests... Any other volunteers to test samples?

Besides standard reef tests, I have access to a chem lab, including mass spec.

i consistently seem to get ~360ppm ca with reef crystals. alk is always on the high end at 14dKH +. I've started dosing my fresh mixed sw with calcium.

i wonder if its how i'm mixing it. i generally fill a 5g bucket with rodi water, then add the salt all at once, then mix with a large spatula, then add a powerhead and let age for at least a day.

i wonder if i mixed while adding the salt, if less ca would precipitate (if thats even the cause of my low rc ca readings)

Same here.. Reef Crystals at 1.026
Ca: 360ppm (Salifert)
Mg: 1250 ppm (Salifert)
Alk: 164ppm = 9.18dKH (Lamotte)
 
Hey Nanz,

My number look almost identical to yours. My Alk however tests at 12 with Salifert.

I have not been following this thread, so I have skipped allot. I don't know why there is still arguing or who is on what side of the issue. F & S had some bad lots numbers with low Ca++, so it would seem. This is not the only forum showing these low values.

From another forum yesterday
SG-1.025
Alk- 4.34 meq/ l
Ca- 320
Mg- ~1145-1200
Nitrate- 0


I have not tested my tank for calcium yet however in the new batch I made last night with reef crystals at 1.025 saltinity all my paramaters were zero except for phosphate which was at 0.5 ppm, ALK 3.6, PH 8.2, and calcium at 350 (using tap water)


For me, using DI water, RC mixes up at 1.025 with around 360ppm Ca and about 8 dKH (2.8 meq/l)

 
Everything's cool Boomer. We are just trying to get to the bottom of this. Seems you may be right. Just for giggles, I ordered a bucket of RC from Drs Foster & Smith. Should be here tomorrow. I recently got a small bag from the lfs and it was fine. I didn't care for the response one of our members got from Drs Foster & Smith so I thought I'd see for myself.
 
Well,

I will say I replied on the Drs forum and they are sending me a new bucket. It will be here Saturday. I'll test that one and see if I get any different results as well :D

Ben
 
OK Billy buddy :D

Just remember guys the new bucket may be OK or not OK. One of you may get a good bucket and the other a crap bucket ;) And we will be starting all over again :lol:
 
I smell what you're stepping in boomer.

But seriously... how funny would it be if I got the good bucket and billy gets the crap bucket... Hmmmm
