Dosing - can't find the right levels.

[viperfish]

What kind of dosing pumps are you using? I ran your Alk numbers (5 to 14.8) on the BRS calculator with your tank volume and it would take 630 ml of recipe 1 to gain that much. So whatever you're adding is some potent stuff. I still think there must be an error on the testing side of things, either with the kit or the method. An alk increase of that much would kill almost any SPS and shock the hell out of any other coral. I'm with fishytime on this one, go get yourself some bulk chemicals, and use accurate dosing pumps. You only need two pumps, the Mag doesn't get dosed as much as the Calk and Alk, I actually use an IV bag for Mag and it works like a dream. Once you have the right hardware, go to the BRS site and follow their instructions to the letter and I guarantee you will have success.
