The other 1% is heavy water. My online research suggests that in studies, fish were exposed to 90% before it was fatal. Thoughts?

were they swimming in mercury at 90%???The other 1% is heavy water. My online research suggests that in studies, fish were exposed to 90% before it was fatal. Thoughts?
Calcium chloride dihydrate, ACS reagent, ?99% | CaCl2 | Sigma-Aldrich This took some doing to find! MSDS sheet and spec sheet for the stuff I listed. Phew!
Heavy water is very similar to water, but the hydrogen [FONT=arial, sans-serif]isotope deuterium is in a larger amount than usual. [/FONT]were they swimming in mercury at 90%???
I'm pretty sure every metal and most chemicals are going to kill the fish well before they reach a concentration of 90%, unless its water
Ah, thank you for that info!its more expensive than a lot of the hobby branded supplements...but I bet it works fine.
Also I just noticed its the dihydrate form which means it will take more to = the same amount in anhydrous.
Someone please correct me. BRS uses calcium dihydrate as opposed to anhydrous because when mixed with rodi it produces less heat and dissolves better. Fritz uses anhydrous flake, and claims thats better? A few of the branded liquid solutions sold in lfs claim they are concentrated to up to 160,000ppm? I thought only so much powder would dissolve in rodi before it drops to the bottom? What is the calcium ppm of the BRS calcium chloride when mixed at their suggested 2 1/2 cups to water. Can we add 3 cups, 4 cups, should we? I am confused by all these labels being so different? Can anyone clarify? How do we test for ppm or is it even important?
Randy thank you for the response and education! Let me repeat to see if I understand. The alkalinity at 2 cups per gallon is a fully saturated solution and wont take more powder?? Hence in order to dose 2 parts in equal portions and not have one level rising more than the other due to concentration levels, you have found that at your 2.5 cups of CaCl or 37,000 ppm is all that is need? Then why do some manufacturers push their concentration to 160,000 ppm? The instructions on the bottle does not say dillute it down before use? This is the argument lfs use to say BRS or other 2 parts are not as good? How do we explain to them the difference?
Dr Fosters and Smith was having a sale on its Calcium Chloride and Sodium Carbonate, 35lb (5g) for $55 each. That is cheaper than BRS by almost $30 each and the calcium is anhydrous, I asked them, so the value is even better and at that price you get free shipping.
