So what is everyone preferred brand to dose with? I'm just getting into the swing of thing and I am about to start to try my had at this stuff. I have some soft corals at the moment but eventually I will have a good mix of an SPS & LPS tank. I'm thinking of using RedSea stuff or I am considering starting just to use Kalkwasser (spec the BRS Bulk Kalkwasser Starter Package) and add it to my top off system. I know I have heard horror stories of the auto top off system emptying everything in at once but I am setting up my neptune system now to monitor all of my level so something like that doesn't happen. Also I just bought the Tunze auto top off system so I'm not extremely worried out it. What is everyone thoughts love to hear some peoples xp and opinions.
