I have a 5 gallon bucket of this stuff. Noticed my fluid in my dosing tank is low today.... Went to go mix a new batch and found that the lid on the bucket is opened and there's water inside. The calcium's turned to a solid block.. Arrrrrggghhhhh!!!!! :headwalls: Not sure what happened or who did this but I've placed an order for some more... the thing is, I won't receive it in time... I'm going to run out in a day or two.... My tank consumes about 150ml of this stuff a day... Not sure how the other formulas in the store measure up to this so I don't want to temporarily use the other brands... So... Anyone have 2.5 cups of BRS Calcium Chloride powder they can sell me???
