MagFlake and DowFlake Group Buy

As I mentioned in another thread I would try to start a group buy for CaCl2 and MgCl2 (DowFlake and MagFlake). What I need at this point is some indication of how much to buy. Please post on this thread if you wish to participate in this ââ"šÂ¬Ã…"œgroup buyââ"šÂ¬Ã‚.

At this point I found a source for both with the DowFlake coming in at about $20 per 50 pound bag plus tax ... and MagFlake at about $70 for an 80 pound bag. I should mention that I reference the products as MagFlake and DowFlake (one of the products that Randy mentions), however you should be aware that the venderââ"šÂ¬Ã¢"žÂ¢s product may not be sold under that name. I have been assured that the product we receive will be the same. The actual chemical name for DowFlake is calcium chloride dehydrate, and MagFlake is magnesium chloride hexahydrate and that is what I will be getting.

My plan will be to offer 10 pounds of DowFlake for about $5.00 and 20 pounds for about $10.00 and 5 pounds of MagFlake for about $4.00 and 10 pounds for $7.00. I say about because I haven't added in the tax, packages to transfer the flake to ... and I expect that the actual prices should be a bit lower than this. When I get an idea of how much we want to buy I will give exact prices but will only deal with multiples of whole dollars and give any excess to the club. Also I will not ship and will only offer for pickup at the meeting or WMC 2006 (assuming I can get it going by that time). Should a fish store be willing I can also drop off there (I will ask John at his new aquarium if that would be ok). I will NOT expect payment up front but can wait until pickup unless someone wants entire bags of product.


When you are deciding you should consider that if you are gong to make up Randyââ"šÂ¬Ã¢"žÂ¢s two part calcium/alkalinity additive (really three part if you include magnesium) that you will need much less MagFlake than DowFlake. Also note that Randy suggests that you mix the MagFlake with some Epson salt to maintain ionic balance. I am not planning on group buying Epson salt. Also note that you will need baking soda for the alkalinity part and I am not planning a group buy for that either. Both Epson salt and baking soda are readily available locally, fairly cheaply, in amounts that would typically support a reef aquarium.
 
Put me down for:
20 pounds of DowFlake for about $10.00
10 pounds of MagFlake for $7.00

I can P.U. at your convienence and even bring my own buckets.
 
I need the same amount as Rich..
20 lbs of dowflake
10 lbs of magflake
I am 1/2 mile from Johns store so I could Pick it up there.

-thanks
 
Well since I think work will eventually figure out that I'm sucking up all the ACS grade Calcium Cholride....
Put me down for:
10 Lbs of Dow Flake..
5 Lb of Magflake (if another nano keeper wants to spilt this LMK)
I think that will last for for a Looooong time...thx.
 
i'll give it a try too john,

20# Dow
10# Mag

thanks for your effort! :)

btw, if anyone is currently using these products, could you please post some pics of your corals? i'm a little nervous deviating from what i'm doing-but chemically if they are made up the same it shouldn't matter.

I use to use Dowflake without a Ca reactor and the only true downside i experienced was that (ceramic) pump shafts would get calcium build up.. and the spike in Ca levels when you add the solution to the tank, but this can be minimized by dividing up the dosage and adding over a period of a few hours..

with the reactor, i only use Dow for the occassional leveling.. fwiw, i've used at the most 2# of Dow with the reactor for the last year..

John,
I would like a bag of the Dowflake at ~$20 and 20lbs of Magflake at ~$14, for a total of around $35 or so. As long as this "technical" grade or better, I think it will be fine for our use.
Let me know if you go through with this and if I can pick it up at John's store.
Thanks,
Donovan
 
Hi Reefers, I talked to John at YourReef this afternoon and he is fine with pickup there. :thumbsup:

I will make up the list soon and will indicate a pickup point (meetings if not specified elsewhere). If someone else wants to talk to a place more in the southern part of town I could do another place also but I don't know anyone in the LFSs in that area that I would be comfortable dealing with for pickups. If anyone can set up something just let me know. I will need a name of who to talk to at the LFS and a number if it is other than their standard number.

I am surprised with the response so far and it looks like I could be buying soon. I guess I should let it go a full week before cutting it off. I will plan on a cutoff of next Monday (04/10/2006) and will order soon after that. I expect that there will be some excess from the large bags and will continue to make it available at the meetings. Please let me know if you see a problem with any of this.

--John

John.. Could you confirm that the CaCl product is "actually" DowFlake?? or is it just "Calcium Chloride"? i.e. the bag will say DowFlake and made by Dow...

reason why it's important is b/c Randy has confirmed the other trace elements in DowFlake to be safe for aquarium use.. other CaCl products my have other unknown elements that you don't want in your tank..

Sorry, at this point, no I can't. The lady I talked to in the bay area said it was DowFlake, but at this point I don't have a way to verify that. What I have to do is buy the product and they will transfer to their West Sac. warehouse for me to pick up. I got the info for the vendor from RasBobre but I don't know if he purchased from them before. If anyone wants to back out due to my inability to verify this just let me know.

-- Edit --

I guess I could expand on this concern a little. The CaCl2 (DowFlake) product we are buying is for de-icing sidewalks. It just happens to also be something that we can use to supplement the Calcium that corals, clams, and the like use in our aquariums. The MagFlake is normally used to control dust. Both products are very hygroscopic which means that they absorb water from the air. Enough water to actually form a liquid solution if left out in the open (consider this when storing the product). In any case there is a danger that there are traces of chemicals in the product that could have a negative impact in our tanks. Randy has tested DowFlake and has read the detailed impurity profile for MagFlake and does not see a concern with these products. One should read both of Randyââ"šÂ¬Ã¢"žÂ¢s articles for the full information.

This is the actual DowFlake.

Thanks, I didn't intend to put this on your shoulders but glad you could verify.
