I just can't take it any more! i had 3 seahorses, and now suddenly i have 2. And on top of that I cant get my stupid Hair algea to go away. Its been there for months. I have tried everything. New skimmer, Phosphate remover, UV sterilizer, Macro algea in refugium, huge clean up crew, Nuidibrancs, water changes with Ro/DI water, reduced feeding, cooking my Live rock, and manually removing it! here is a pic of my tank exactly one week from scrubbing it spotless with a tooth brush, and doing a 30-40% water change. <img src="http://img.photobucket.com/albums/v411/whatnot45/ickyaquarium.jpg" border="0"> And about that missing Seahorse, it just dissapeared without a trace. It showed up at the feeding station one day, and the next it didnt. I thought it just was hiding and so i left well enough alone, but after about 3 days, i decided to look for it i removed everything, and it was no where to be found. Nothing in the tank could have eaten it.... I do not have mantis shrimp or anything like that.... the only tank mates are some soft corals, a couple SPS frags, and a jaw fish....
