DampRid
I'm just wondering about the product DampRid. It says it contains Calcium Chloride. Isn't that the same thing as Dow Flake? I get a 42 oz. carton of it at Home Depot for about $10. I've actually already used it a couple of times and I haven't seen any negative side effects. It is marketed as a moisture absorber. I also just took a trip to New Hampshire for the first time. It looked like people were using the same product to melt snow. Do you think this stuff is OK to put in our tanks? Thank you

I just looked it up. Here is a link to their site. It looks like I can get 6 of the 42 oz. cartons for a lot less than at Home Depot.

It is a similar chemical, but unless you do a very expensive chemical analysis, or a lot of tank trial and error, it is not possible to know if it is adequately pure.

Here's a bump for us people down south who have trouble finding the de-icers.
According to the MSDS for DampRid, it's 74-100% calcium chloride with probable contaminants of calcium carbonate, calcium hydroxide, calcium oxide, alkali metal chlorides, and alkaline earth metal chlorides. It sounds pretty safe to me since the purity is similar to Dowflake and most of the contaminants listed are things we already add to our tanks. What's your take?

I've already got lots of DampRid now, so that's the main reason I ask.
The one pool store I know of in town does sell 90% calcium chloride, but they only have it in 45 lb buckets, which would last me forever. I might be able to spread that around back in Huntsville, but I really don't want to have to lug around a huge bucket of it back and forth from school trying to pawn off what I can't use.

I checked into it a long time ago as there is a lot of the product around here. I contacted the company and if I recall correctly it was Tetra Chemicals Calcium. (I might be wrong
 ) anyway they did not have a detailed breakdown of the impurities so it is still a guess. Sure would be nice for someone who has all the high tech equipment to test it out as it is more common than Dowflake and available year round.

My take, as always with any random brand of calcium chloride, is that it may be OK, and may not be. It is a risk you take if you use it. if you do try it, first measure ammonia to make sure that is not too high, then start very slowly with it. I test Dowflake for ammonia with a test kit here: Purity of Calcium Chloride http://www.advancedaquarist.com/issues/mar2004/chem.htm Sure would be nice for someone who has all the high tech equipment to test it out as it is more common than Dowflake and available year round The problem with any secondary product like this is that they may change bulk suppliers weekly, seasonally, etc. So just because it is Ok for us one time, it may not be OK another. Their only obligation is to make sure it meets their own specs, not ours.
