As Richard mentioned...it's seems as though the lazy way of fixing a problem doesn't even address the issue that caused the problem. I think that is where we should all start first. Find the problem and correct it...you can't erase it. It will just show up again.

Sorry for your loss. I take a natural approach to everything....unfortunately that can seriously test my patience but I can avoid crashes and large amounts of loss at once. I've been at battle with neon green slime for some time now. I finally have it under control but it's not gone yet....hoping I can possibly choke it out by increasing my macro with a larger sump/refugium that I plan to add soon.
