Well, it has been 5 or so weeks since my tank made it down to a sg of 1.009. The tank has been ich free for almost 4 weeks. I am going to raise the salinity starting this week. I did encounter one problem in that my refactometer broke and I am not sure exactly when. My tank is slightly out of hypo right now at 1.014. I am pretty sure the jump happened within the past week.
I have lost a decent number of fish from ich. I lost my two clowns, although they seemed to have some secondary infections going on that I just wasn't able to heal. They improved for a few days in a hospital tank before going quickly downhill a week later. I lost my emperor angel. He was hit the worst by the ich. I also lost my powder brown tang, who got ich pretty badly. My sailfin tang and green bird wrasse both had ich badly, but have since been ich free for about a month.
In other news, I re-did my plumbing a week ago. I added a 14g refugium next to the sump. It sits a bit higher than the sump and uses gravity to drain water into the sump to avoid overflowing (no pump). The drain line from the tank to the sump now has a tee to run over to the fuge. I do have one problem though, my fuge is leaking water and so I have closed the ball valve allowing water to drain to it and disconnected it from the system. I am planning to replace it with a 10g if I can drill it for a 3/4" bulkhead.
Also, I am a proud new owner of the SWC 250 Protein Skimmer. I got it from my parents for christmas. It was working great, even in hypo. I did have to send one pump back due to a noise issue that I know shouldn't be there. I should have the pump back within a week.
I should be posting pictures in the next week or so of the changes. The tank looks like crap right now because I haven't had time to mess with the powerheads, so they have been blowing the sand around. I currently only have two MJ-1200 with mods running. I am going to go back to the 1600 gph propeller and then run all four.
