I need to respectfully disagree here when it comes to ich. 1.009 is the recommended salinity for hyposalinity treatment of ich, with a minimum duration of 2 weeks since the average lifecycle of the ich parasite is 2 weeks at normal reef tank temps. 4-6 weeks is fairly common and gets even better results since the parasite has to go through more lifecycles. Your call as to whether you boost the tank temp while you're doing this. Some studies have shown that a salinity as low as 1.011 is ineffective at killing ich.
I know we're getting a little ahead of ourselves, but it's quite likely that Peter's fish will experience ich not long after he begins buying them. IMO, for fish diseases, these are the two best references on the web:

Peter, I absolutely agree with you. I only offered hyposalinity as a suggested possibility. Please see others' suggestions above, as well. I didn't intend to start a war or to dis anyone's opinions.nineball said:The problem I have Dave is that there was no indication from the staff of any treatment programs under way, in fact there was a sale on all fish livestock in the store. I assumed when I asked the clerk for the temp and salinity that he should have warned me that the fish were undergoing treatment for ich if in fact that was the reason for the low salinity. We are assuming that would be a plausible reason for the low salt. It also could have been a simple economy move however silly that may be.
I've been lurking for a while...
This is really an amazing thread and build! Your candor, honesty, respect for others, as well as your opened-minded wiki-style (community knowledge) incorporations makes for an epic experience for the readers.
Looking at the plumbing, a question came to mind (I am an utter novice, only have a 14G nano-reef). My background is in engines. An engines efficiency can be enhanced greatly by having equal length intake runners and exhaust pipes (like the beautiful snaking exhausts and intakes on exotic cars).
Does this concept transfer to the efficiency of the pumps and water circulation? Was any consideration given to making all the circulation loops equal length? It seems to me (I don't know if correctly or not) that it would be beneficial to have each pump and loop operating at equal pressures and flow rates so as not to cause any one pump from working harder than another.
Perhaps a better question is: Is it necessary or desirable to give any consideration to the loops in regard to pressure/flow/head equality?
Thanks so much, and I am really enjoying your build.

Thanks Peter for the kind words ... Gary will be at MACNA this year as well so you can meet us both! I was just kidding about driving your car and drinking your wine ... Gary had to one-up me and go over the top explaining his thread of the week so I had to get him back
I thought I was looking at a fine Boutique Fish Store when seeing the pics of your Mars system! It looks so perfect in that fishroom!
The MARS system and tank are stunning. This is going to be a great tank to watch grow. Keep up all the good work.
Love the progress you guys have made and I can't wait for the pictures of the aquascaping!! This has been such an informative thread with all the debates and discussions on what and what not to do. Simply amazing!!
Sara you are more than welcome to drive the car and drink the wine. In fact, in the Bentley you can do both but not at the same time and you need to find a different juristiction where it is not against the law. That may be far away from here but at least you can get there fast!!!!
I look forward to meeting you both.......
I was thinking of taking some of the thread people out to dinner if they were there Thurs night. I wonder if there's anyone else here who is going to the MACNA. Mr. Wilson and I will be the hosts. We thought we would find some sea food!!!!
Peter
mmmmmmm mars bars.....

wow, just wow!
An LFS that keeps it's fish at hypo-salinity is mostly doing so because they have been imported/exported at hypo-salinity, it's economical to keep them that way or they believe it is beneficial to the fishes health (and recovery from import/export stress/disease/illness) as it decreases osmotic pressure on the fish (no conclusive scientific evidence for this though). That is what I was told by the owner of my LFS who worked at several others stores before starting his own shop. He always works with 35ppt because he believes it keeps customers and :fish1: happier in the long run.

The lifecycle of the parasite is interesting and important to understand when evaluating a treatment. The stage where the parasite is attached to a fish is called a trophont. The trophont will spend three to seven days (depending on temperature) feeding on the fish. After that, the trophont leaves the fish and becomes what is called a protomont. This protomont travels to the substrate and begins to crawl around for usually two to eight hours, but it could go for as long as eighteen hours after it leaves it's fish host. Once the protomont attaches to a surface, it begins to encyst and is now called a tomont. Division inside the cyst into hundreds of daughter parasites, called tomites, begins shortly thereafter. This noninfectious stage can last anywhere from three to twenty-eight days. During this extended period, the parasite cyst is lying in wait for a host. After this period, the tomites hatch and begin swimming around, looking for a fish host. At this point, they are called theronts, and they must find a host within twenty-four hours or die. They prefer to seek out the skin and gill tissue, then transform into trophonts, and begin the process all over again (Colorni & Burgess, 1997).
The issue for me isn't that the LFS keeps low salinity as much as the misinformation. When I asked what the fish I had just bought had been used to for temp and salt I was told 1.021 and 78 F. If I had not checked before I might have been less careful about the transfer.
I wouldn't object if the LFS told me that it was lower salinity. The other aspect that is troublesome is that the level was 1.003 which according to conventional wisdom on this thread is waaay too low.
I think we will all be better off when you can ask an employee of the LFS what the standard is and get an answer that's more than pure speculation.
