My LTA got sucked into a powerhead a few months ago, he was wrapped around it "face first." That sucked! I turned off the powerheads and he unwound himself over time. I have all my intakes now covered with nylon (stockings from wal-mart).
I usually have no ammonia, no nitrites, nitrates usually around 15 (between 10 and 20) ph
at 8.2 (although it was low, so I added buffer) but generally the readings are usually really good. I'm working on getting the nitrates down more and the phosphates.
The anemone is "stretched up" again today, as opposed to his continued squat for the last couple days. All of his tentacles are inflated and he seems good. Can't wait for tomorrow to feed him again. Today, he snatched up little pieces of mysis when I fed the fish, so I think he's pulling through this HUGE mistake that his horrible mommy made!
