I added the BioCube skimmer with a neck mod made of PVC, it raised the skimmer cup almost 3 inches and it started skimming really well. I also started running GFO and kept up on my weekly 5 gallon water changes. At the start of this thread, it was only on one rock. It's now on all the rocks, though it's small. On a scale of 1 to 10, i'd say it's a 2 or 3 right now. I read through the huge Dinoflagellate thread yesterday and one guy beat it by dosing MB7 and phyto every day. I guess there's a theory that lack of biodiversity allows the Dinos to grab hold. Another guy let his SPS tank get completely overrun by them to prove he can consistently kill it. He dripped kalk and reached 8.6 pH, gone in a week or two. I plan on doing a blackout soon and trying the biodiversity thing then go from there. Since it's not really bad yet, i'm hoping the blackout alone will be enough.
