    OMG I had another scare - need some advice

    Over the past several days I've had a scare with my fish. We had a power failure on Sunday and I added StressCoat to the water "just in case". That means I had to shut off the skimmer because it turns the tank into a jacuzi there are so many microbubbles. Over the next few days the fish developed cloudy fins. I treated the tank with Melafix and more StressCoat. Yesterday they started panting (laboured breathing, gills going fast). I was getting advice from a couple disease specialists and preparing for the worst. This morning they were all listless and looking bad and they didn't show much interest in breakfast. Then I noticed my coral banded shrimp way out in the open - something he NEVER does during the day.

    I started looking for other problems. I did water tests yesterday and everything was great but I tested pH this morning and it was very low 7.6. I add kalkwasser to this tank every day to keep the pH up but it shouldn't have gone this low. I started thinking about oxygen. The skimmer had now been off for 5 days and although I have a huge amount of circulation in the tank it's completely enclosed.

    I turned the skimmer on and let it do the jacuzi thing anyway. Within a half hour the fish were revived. Within 3 hours there was no more panting. Tonight the fins are almost completely clear again. I put some carbon in one of the canister filters to help get the Melafix (that I didn't need) out of the water. I'll do a water change tomorrow to help get more out. The fish definitely don't like all the bubbles but they're fine. It's kind of scary having my tank that dependent on the skimmer though. I think even with the skimmer on there's not enough new fresh air getting in.

    So, apparently I have an oxygen problem in this tank. To see what I mean by "enclosed" check the setup pics here:

    I bought a nice big muffin fan that I can put in the wall at the end of the tank to blow some fresh air in there. With the "wall doors" closed there probably isn't much fresh air getting in. I have an exhaust fan on the opposite end of where I will put the muffin fan. I also have a really big air pump that I'm thinking I can use to pump some of this fresh air into the tank or at least under that enclosed top.

    You guys think that will do the trick? Any other suggestions?

    OMG, thank goodness you figured out the problem before it was too late. Lord knows, you've had enough probs as it is. I actually have the same issue with my new tank and so I keep the skimmer going at all times just to be on the safe side. It is completely sealed except where the skimmer flows and the cords from various devices come out. Because I don't have room for fans or such I have no choice but to keep the skimmer going at all times or else have my wooden bubbler going which I find puts out too many bubbles.

    Is there no constant ripply of water on the surface of the tank.

    I have a powerhead 802 angled so that part of the output stream causes a lovely ripple across the water surface.

    Did you notice any film build up on the water surface.

    My recommendation is to take off the lids and get some surface agitation going with powerheads. Just run your exhaust fan to keep the humidity under control.

    If you install the muffin fan in a way that one side is inside the wall and the other side is outside, say in your kitchen. Then it will do the trick.

    Alternately, no need to install the muffin fan. Just create some nice openings at the bottom of one or two of your wall doors. Then just let the exhaust fan do the work.

    LOL. they taste too much like coffe crisp bars for me. As a sailor its a written rule that I'm not allowed to get a hangover, or is it due to the fact that we tend to drink too much.LOL either way it works for me. But back to flames problem, Flame a premixed drink of good ole newfie screech is in the mail to you. It will calm your nerves and send a tingle right to your toes. Hard luck for such an experienced reefer like yourself. But I'm sure it will all work out. Best of luck to you.
