I have one berried now, noticed it this earlier this week. My 55G at work has driftwood in it and I'm wondering it was too acidic for them since I didn't really boil it. prior to that, I added about 1/2lb or so of crushed coral in a media bag into the filter.
I see others have used Kent's liquid products which I have for my reef so I wonder why they don't work so well when the micron size is the same as DT's live phytoplankton? I got the powdered stuff too but hoping they don't require live to make it easier to raise.
I have the large Marina hang on tank that I'm going to throw them in. I use it as a cheap refugium with chaeto now.
