information on lab grade calcium chloride

[tigershark]

hi all, anyone of you using calcium chloride? may i know where to buy it? i intend to use it as drying agent in my DIY dehumidifier + calcium supply to my tank if the price is rite....

anotherquestion would be, any side effect on using calcium chloride? eh, PH? heavy metal.... how to use it? i've been using calcium hydroxide so far and never use calcium chloride before.

thanks in adv.

unformulated calcium chloride would give ur tank a swing in ion inbalance.

and certain lab grade product would result in heavy metals content .

thanks woonming, you seem to be very particular with heavy metals content as there is at least 5 post from you regarding this issue........ anyway, its good to becareful since we have invested so much money into this hobby.

anyway, is there any member here who have lobang on calcium chloride & calcium hydroxide (kalk)? i remember sometime ago there was a post saying 500g kalk/calcium hydroxide selling for $10 only, but i can't find the post . any kind fellow who can provide me the infoon w here can i get it from?

because that is the only factor other than purity level that what most reefers would look out for in different brands.

I think that it is unlikely that Lab grade calcium chloride (CaCl2) would be contaminated by other form of harmful heavy metals. Well it depends on what type of heavy metals we are referring to, Ca is a type of heavy metal too but it is benificial. However, I am not sure if the type of Ca ions that is introduced from CaCl2 is the type that will be assimilated. Some times these metals must exist in a certain complex form before the corals can assimilate them.

CaCl2 is a neutral salt, dosen't cause hydrolysis of water. That is the pH should not be much affected.

I doubt its usefulness as a drying agent considering the ones we are getting as it is already hydrated - it had already absorded moisture.

I can check on the price of the chemicals, but that might that a few days as I am on holiday now. Cheers

I overlooked the fact that Ca ions can precipitate out carbonate which can cause the pH to drop slightly. However, I am sure that the pH will surely be well above 7.

I had just check with my lab technicians regarding CaCl2. They do sell anhydrous ones. IMHO given the high humility here, they will get hydrated in a short period of time - just like leaving potatoe chips for a couple of hours, they become 'lou hong'. Will update you on the price when I get hold of the catalog

That means that you will be using calcium chloride as your main calcium supplement. 'YES' there will be problems in future.

'YES' it does have a side effect. (but its not heavy metals)

Calcium alone is not enough, because the availability of carbonate mostly depends upon pH and alkalinity. Skeletal growth can still take place if alkalinity is high, and the calcium concentration is much lower than that of sea water. However, if both are low, these calcareous animals and plants do very poorly and little growth occurs. The bottom line is that calcium, carbonate, pH and alkalinity all relate to one another. To attain a thriving reef all of these elements apply, not just calcium by itself.

Anhydrous calcium chloride can be used on occasion, to help boost Ca levels back up to the range you desire. Then the clear solution of calcium hydroxide(kalk) should be used to help maintain these levels. In most situations, the Ca levels will fall slowly over time and require another boost of the anhydrous calcium chloride to return to the range desired. Always use anhydrous calcium chloride with care and sparingly, overuse can be disastrous to your tank.

The use of Calcium Chloride (CaCl2) is known to cause problems with alkalinity (provable by balancing the relevant chemical reactions occurring in the tank when CaCl2 is added). Still, CaCl2 is occasionally useful to repair serious low calcium levels.

so in short- calcium chloride can be used as a booster(just to raise your levels to desired) with no major side effects but used constantly will leave you spending more time balancing your ALK(& when u mess with these 2 parameters you pH will also be affected)...it will be like playing with a yoyo or see-saw.

i'm not saying you shouldn't use it, just know what it is and how to use it and you will not encounter problems.

i see.... thanks bawater, so far, you are the only 1 who gave me a best picture.... not that other cannot explain but your explanation is easier to b undestoon to a layman like me

anyway, still there is no one who can update the lobang of the $10/500g kalk and/or calcium chloride lobang? i'm very sure i've seen the post somewhere but juz dun know why I can't find it.

Thanks for taking time to explain these stuff . I had been enlighten. Felt really uncomfortable to add a chemical and not knowing what other parameters could be affected. Really make sense now. Cheers

i dunno abt calcium chloride prices-

$10 kalk for 500g is available at many LFS at the moment but its just for a limited period .

Reefez announcement

Reefez is sold at bio-ocean and many other shops at this price for the month of NOV/DEC.

The grade is pretty high .Apart from the GCE LAB grade calcium hydroxide(not sold in LFS) no other kalk makers are willing to give a high % rating on its ingredients. 90% and above is pretty pure and reefez states 96%(GCE is 97%).

(the higher % means there is less of other things in it like heavy metals,other chemicals,dead bodies,old houses,etc)

And there is no 100% pure calcium hydroxide sold to the hobby.

thanks bawater... will go and find it.... by the way, anyone have any idea any LFS at North side selling reefez product?
