I have had some Mrs.Wages sitting unopened for a while now, not sure what to do with. Decided to do some research and make some kalkwasser and see how it goes. About a week into it and everything is finally starting to flourish!! I know your supposed to drip it in but I just use it as normal top off added slowly over time and so far so good. Cant believe Ive been reefing for this long and just started using it. My only complaint is not finding out the benefits sooner lol. Anyways those with SPS dominant tanks should do some research and find out if its the stuff for you!
