However if enough people get on board and we have excess funds we could run the tests again in 3 months or so with different batches and check for any differences. Something along those lines. While I'm sure there are slight variances I don't think it would be enough for us to even notice with out test kits. Most of the "off" values people get IMHO are from settlement in the buckets/bags. Most people just start at the top of the bucket and work their way down and because of settlement the bucket could have more calcium for example when you first start and be less toward the bottom of the bucket. That's why I always completely mix every bucket I get for about 15 minutes (dry powder) and then move the salt into storage bags weighed out specifically for X gallons each. Then when I'm ready to mix salt I fill with water (marked water line) and slowly pour in the salt while it mixed. Near perfect 35% salinity every time and consistent for the whole bucket. I added you to the list and PayPal will be fine when the time comes. Carlo |

Their prices aren't too bad either, we paid .30 a gallon.

multiple studies would be interesting, certainly something we can do down then road.
i'm planning to send a sample of my freshly made saltwater (i'm using 50/50 IO/oceanic right now) to AWT just to see.. i received a reference kit from them the other day, was shipped very quickly.

It would be great if this company also did SG with these tests. Without that it could really mess up the results. |

Yea I agree. Salinity is an easy thing to check. Heck they could pick up a Pinpoint Salinity meter cheap which is good enough. Then people could compare their hydro/refracto meters to the tested report.

I got $10 bucks on it, send me a pm when you need it. Can we get a 50/50 Oceanic/IO mix into there. Several of us use it (including me) and are curious.

Maybe we should "hold back" the results for 30-60 days before everyone not contributing get's to see them them. Carlo |

I'm more interested in the results then getting money back I've worked in this industry long enough to know when it's proper to give back, and nows the time

Then we can test or own samples against that for reproducibility. |

Way cool Gresham!
Put me down for $10 (let me know when and how, paypal would be great). Also, it would be really nice to include KZs Reefer's Best Salt since its the most expensive salt out there and claims to basically mix to NSW standards. Hopefully someone can supply some because I don't have any and KZ's importer (Captive Oceans) is also out for a while. James

People willing to contribute
cayars Antman Boomer HowardW Dr Begalke tkeracer619 jamesdawson GreshamH for up to $100 KZs Reefer's Best Salt would also be a good one to get done if we can get a hold of it. Carlo |

oh i'm down for this also.....
Even if we can't raise funds to do all the brands i will still send out what i use[RC]!! |

I can chip in a bit. This sounds like a great experiment!

Good news, I found another contributor!
I emailed aquariumwatertesting.com letting them know of our basic plan, and here is what I received back: "Hello Dr. Thank you for your business and your consideration on this analysis project. We would not only be interested in being involved, we would be happy to donate our time, facilities and resources to compile this data. You guys don't need to gather funds for the testing or the provsion of the salt mixes them selves. We will be happy to take care of all that. We had a meeting this morning to discuss this and we decided that it would be best if the salt was mixed here to remove as many variables as possible from the equation. What we would like for you to provide us is a complete specification for the project. Our thoughts are to run the 14 parameter panel on each of the 15 (including Catalina) salt varieties you listed on the thread. We think that buying one bag of each brand from the east coast and one from the west coast and testing both bags might yield some information on relative consistency from batch to batch. So we are thinking two panels for each brand. Tell us, though, about any details that will be important to you in terms of the testing procedure (concentrations, time after mixing before testing, etc...). We look forward to working with you to produce a truly valuable data set! Maybe this could become an annual review to account for formula changes and new market entrants. Thank you again for considering us and for signing up for a Reference Kit, we really appreciate your support! Jeremy Redmond AquariumWaterTesting.com" So please chime in with your thoughts on the specifics for the testing protocol and I will get them to Jeremy at AWT!

Can't think of anything right off hand, but way to go doctor! Outstanding!

I would think a standard salinity (1.025-6), standard temp (not sure if temp affects any of the tests they plan to do), 48 hours of mixing, with the last 24 of those with aeration....
An excellent venture. Kudos to the Dr.

Chris, thanks! I'm excited.
Here is what I was thinking: 1) Test the RO/DI water, try and use the same batch for all the salts. 2) Mix to 1.025 SG. 3) question about how long to mix the water? I usually mix for 1 to 2 hours... but I know some people mix longer. 4) question if temp is important? i usually adjust the temp, but i don't know/don't think this would effect too much...

Don't let the salt companies know about this.

Peter, thanks! I have the same questions about the temperature... I would think as long as they are all the same (ie all at room temperature) then it shouldn't effect the results. If we tried to control the temp, that would probably introduce more variabilty into things...
kysard1: we shouldn't have to contact the salt companies
