[TANGOMAN]

Ever have one of those days when you're "kikkin'" around the house and the tank lights come and it's like "what the %@~! is goin' in there ? Well todays MY day. My tank, the 60g corner, is clouded in like the Vancouver airport. The Caulerpa growth that was doing so well is "bleeding out". A similar occurance happened a couple of weeks ago but minor in comparison and it was clear the next morning. I did do a 5 gallon water change yesterday and I noticed a slight smell that was different. I haven't seen my Emerald Crab for two days and I figure if I don't see it in another day or two a search team may have to go in to gather the remains. Or should I leave it and let the hermits clean it up ? The tank has been without fish for a few months thanks to some un-invited parasites I'd rather not talk about. My "beginner corals",mushrooms,and inverts.(aside from MIA "Gringo the crab") are all doing VERY well. I haven't been adding Iron supplements for the Caulerpa as it was doing well without and it's not the only form of algae that benefits from it... I do my partial water changes religiously and I am using Iodine, and Strontium/Mb supplements.
Foam production in the skimmer is nil today, a result of the oils released from the Caulerpa can I presume ?
So, Bla,bla,bla,,,Should I supplement with Iron in the absence of fish ? Should I remove the Caulerpa that is dying or all of it ? Increase flow through GAC canister ? Or should I just turn the lights off and go do some maintenance on my 90g ? Thanks for any input. Doug.
