cracker Posted July 19, 2005 Report Share Posted July 19, 2005 Technical grade Calcium and Magnesium for those of you who are not interested in owning, or dont have reactors. I have these chemicals available if required. PM me if needed. VERY well priced. Quote Link to comment Share on other sites More sharing options...
RnB Posted July 19, 2005 Report Share Posted July 19, 2005 how much for magnesium? Quote Link to comment Share on other sites More sharing options...
cracker Posted July 19, 2005 Author Report Share Posted July 19, 2005 $4.00 kilo Will be available in a couple of days. Quote Link to comment Share on other sites More sharing options...
RnB Posted July 19, 2005 Report Share Posted July 19, 2005 what form the magnesium in and how dosed? thanks Quote Link to comment Share on other sites More sharing options...
cracker Posted July 20, 2005 Author Report Share Posted July 20, 2005 It is around 98% pure Magnesium Chloride. It comes in "Prill" form which is similar to bean bag filling to look at. Very simple to dose. 1: Take tank reading. 2: If low add specified amount to a jug of Top off water and mix. 3: Chuck in your sump! Thats it. I can give you approximate usage per litreage if needed. The Calcium works exactly the same. No need for Kalk stirrers and all that crap. Just dump straight into the sump. If no sump, drip feed straight into tank. My Acros are colourful enough for me and I have been using this system for 4 months odd. Im not here to make money, just help make reefing easier for everyone!

Drifty Posted July 20, 2005 Report Share Posted July 20, 2005 and its completely safe? Sorry probably a dumb question Quote Link to comment Share on other sites More sharing options...
cracker Posted July 20, 2005 Author Report Share Posted July 20, 2005 Absolutely. WASP...where are you!! WASP I'm sure can answer questions also. These products are probably more pure in many ways than some of the products sold at retail stores. They do need to be buffered along with sodium bicarbonate which is available at your local supermarket. food grade bicarb is more pure than technical grade bicarb. (Human Consumption) Technical grade bicarb is sold mainly for pool usage and the likes. Quote Link to comment Share on other sites More sharing options...
wasp Posted July 20, 2005 Report Share Posted July 20, 2005 Oh! OK I just got back. Yes I've been using these same products and they can do a good job. What Craig is doing is similar to this http://www.advancedaquarist.com/issues/ ... 4/chem.htm or at least the chemicals Craig has can be used to do what the article says. An excellent way to get your levels right if economy is the goal. Quote Link to comment Share on other sites More sharing options...
Brianemone Posted July 20, 2005 Report Share Posted July 20, 2005 so is the calcium just "kalk"(calcium chloride) like most of us use already?? or something else? Quote Link to comment Share on other sites More sharing options...
wasp Posted July 20, 2005 Report Share Posted July 20, 2005 Do think you are going to cheap though Craig, you should at least add a bit for your time! Quote Link to comment Share on other sites More sharing options...
wasp Posted July 20, 2005 Report Share Posted July 20, 2005 Kalk is calcium hydroxide, and does the calcium and the carbonate. Disadvantage being it screws around with your PH and can also precipitate Po4 which some don't like they want it available for removal Calcium Chloride will boost your calcium independantly of carbonate alkalinity Quote Link to comment Share on other sites More sharing options...
Brianemone Posted July 20, 2005 Report Share Posted July 20, 2005 so your offering caclium chloride? just making sure ive got things right Quote Link to comment Share on other sites More sharing options...
cracker Posted July 20, 2005 Author Report Share Posted July 20, 2005 Thanks Wasp, I have allowed for a little bit of Time! Its not super expensive. Yes Brian....Calcium Chloride, (Technical grade) Calcium Hydroxide also needs to be left to settle, similar to Kalkwasser. Personally I dont have time for that!

cracker Posted July 20, 2005 Author Report Share Posted July 20, 2005 I am currently in the process of getting information regarding the amounts and testing for epsom salts which is used to help remove high concentrations of chlorides etc over time. Will post when have more info. Quote Link to comment Share on other sites More sharing options...
wasp Posted July 20, 2005 Report Share Posted July 20, 2005 Quick and easy recipe for using epsom salts ( magnesium sulphate ) - mix one part epsom salt with 10 parts magnesium chloride. This will dose magnesium to the tank with almost exactly the same ionic balance (sulphate against chloride) as occurs in NSW. Epsom salt can be used alone, but will over time result in an unnaturally high proportion of sulphate ions. Quote Link to comment Share on other sites More sharing options...
cracker Posted July 20, 2005 Author Report Share Posted July 20, 2005 Nice...I will see if that coincides with information I'm about to receive. Quote Link to comment Share on other sites More sharing options...
wasp Posted July 20, 2005 Report Share Posted July 20, 2005 Here's a article about it http://web.archive.org/web/200010171320 ... efault.asp Here's a quote from it - "Natural seawater (35 parts per thousand salinity) has 550 millimoles per liter chloride ion and 28 millimoles per liter sulfate ions. Magnesium is accompanied by two moles of chloride per magnesium in magnesium chloride, and one mole of sulfate per magnesium in magnesium sulfate. Working through the math, it turns out that if one took 10 moles of magnesium chloride and mixed it with one mole of magnesium sulfate, one would wind up with a mixture that had almost exactly the chloride/sulfate ratio of natural seawater."

cracker Posted July 22, 2005 Author Report Share Posted July 22, 2005 http://web.archive.org/web/200010171320 ... efault.asp http://www.advancedaquarist.com/issues/ ... 4/chem.htm Ok...So people who are going to be using this system like myself, please be aware that you need to buffer with Baking soda, (From the super market) to raise your KH level. Supermarket baking soda, (Sodium Bicarbonate) is more refined than technical grades as it is for human consumption. Using this system also requires epsom salts. Decent water changes are also required, but we all know that anyway! you can either read the www links that WASP supplied, (ABOVE), or simply mix one part epsom salt with 10 parts of magnesium chloride, (DRY) and then add approx. 3 small cups to five litres of water in a pump bottle or similar. approximately 5 or 6 desertspoons of this mixed liquid will raise Magnesium levels by about 30-40 PPM for every 300 litres. This is a guide only, you will have to esablish the exact amount yourself. 3 cups Calcium Chloride to a five litre bottle works out about the same as magnesium, (5 or 6 desertspoons = a bit less, 30-35 PPM per 300 litres). I add the above as follows: 1: every Sunday I check my levels. 2: Calcium is generally around 380-400 4: I add enough premixed calcium liquid to up my levels to around 450 5: I do the same with magnesium. (It is normally around 1200, I bring it up to 1350. 6: I add enough baking soda to bring KH up to 10-12. (1 heaped teaspoon adds about 2 KH to every 300 litres) I simply dump the contents straight into my sump one after the other. This does not shock the system if done weekly. If longer periods are evident I suggest adding them over a couple of days. PLEASE NOTE: this is a guide only, and the levels i maintain may not suit your requirements. Any other questions please ask.

wasp Posted July 22, 2005 Report Share Posted July 22, 2005 Craig I'll definately take a couple of kilos CaCl2 when we next meet for water transfer, or whatever. Cheers Quote Link to comment Share on other sites More sharing options...
Ira Posted July 23, 2005 Report Share Posted July 23, 2005 Calcium chloride is spa pool chlorine, isn't it? You can buy it for $20 for about 3 metric tonnes at pak&sav. Quote Link to comment Share on other sites More sharing options...
wasp Posted July 23, 2005 Report Share Posted July 23, 2005 You can also buy it at Hollywood for around 50 bucks for one kilogram. All depends on the purity. Quote Link to comment Share on other sites More sharing options...
