Nope, and Im glad to see im not alone in using these.... I have plenty of other "basic" products I use as well. What other cocktails are you using WB?!
A lot of ppl starting out in reefs that I know are really hesitant when I say, "hey you should use pickling lime juice" instead of kalkwasser for your reef when you do WC's. LoL, most of them think im trying to kill their reef or something....
