Pool Calcium

[skriz]

I remember reading somewhere that there are only certain brands of pool calcium one should use in the tank.

What are these brands?

One of my concerns with pool calcium of any brand is where their calcium chloride comes from. Unfortunately for us reef keepers... DOW supplies a large part of the world's calcium chloride and they changed their manufacturing process to include high levels of bromide. This change in process occurred in early 2007. Any DOW calcium products predating that should still be ok though.

its called "pool seasons calcium"

Is this flake or pellets? What do they costs?

Does anyone no if Prestone calcium is DOW?

I've used leslie's hardness plus for literally going on 10 years now. Never had an issue with it.

Is that calcium chloride?

97% pure calcium chloride per the site

Kwl1763,
thanks

How's your tank looking lately. I assume you finished it, do you have a link to your tank build post...?

Prestone is Dow I believe. There should be a date on each package though that you can check. Twopartsolution uses Dow as well, but they have maintained they stockpiled and are selling only pre dow process change stuff.

pool seasons is pellets.

I called a pool company and they told me they had what I needed.. Cal hypachlorite (sp).. Did some reading... Def don't want that.. Turns to cal. Carbonate and then release clorine.. Yikes.. Let me know if anyone is going out soon to get some of the good kind and wants to split a bucket..

Prestone Driveway Heat seems cheaper than the pool stuff. $7 for 10 lbs at Publixs. I looked at the date of the last Driveway Heat i bought 5-07- 04 it was on the shelve a loooong time.

DO NOT use this without extreme caution! In fact, don't use it at all for your aquarium really.

Calcium Hypochlorite (pool shock) is Ca(ClO)2, not CaCl. In water, it's not much different than calcium chloride. When mixed with organic materials (oils, in particular), calcium hypochlorite becomes incendiary and potentially explosive. For example, this is what you can get with http://www.youtube.com/watch?v=ETdYu6H0p58">pool shock and brake fluid</a>. Skin contact can cause burns. The reaction does not need any starter flame or catalyst other than contact.

Yes, it looks cool. It's not. Exothermic reactions are not toys. Depending on the organic used, the reaction can activate after minutes or seconds.
