Roger - please help with my new 9010!

Roger,

You might remember me - I asked about why my skim was blue colored. Well, I can report that after three days of blue skim, the color gradually changed back to the dark green that I am familiar with.

Now, however, after many days of working great and pulling off 200-300 cc of skim each day...it appears that my 9010 has stopped working (?)... Can you just confirm from my description that things seems to be OK?

I pulled the skimmer forward in the sump today (only about a one inch re-position)...and in doing so, one of the rubber suction cups fell off (it actually worked and was holding tight to the bottom of the sump). In order to retrieve it, I took the skimmer out of the sump. After retrieving and replacing the suction cup, I put the skimmer back in. Since then, no more foam! It has been almost eight hours - so I don't think it was just because I stuck my hand in the water.

So I just took the thing out, took it apart, made sure there was no debris clogging anything and put it together carefully to make sure all was properly connected.

Now, here is what I have:

The pump is working.
The drain pipe and drain hole in the back are draining properly (looks just like it used to). There is no water coming out of the ozone hole.
The water level inside is right at the level of the pipe/drain hole (is this proper?) and there are some very fine bubbles being made.
The blue screw is in place, but loosened almost all the way.

All of these things seem right to me...and, as I said, I do have water flow and bubble production. But the bubbles do not rise into the cup at all, they don't rise into the column coming into the cup, and there is no actual foam being produced (just bubbles)....

Have I missed something here? Did I break something when I moved the skimmer? I'm very nervous about this and any advice would be appreciated.

It might be the venturi line is kinked or not properly inserted. Barring that, just give it some time, skimmers can take a while to restart if disturbed.
 
OK. I'll sleep on it.

One specific question however - where is the water level supposed to be in a properly functioning 9010? Is the water supposed to come up into the column or cup at all?

Paul
 
No, if water exits the tube and a normal amount of air apears to be mixing inside it is correct.
 
Thanks for the continued great customer support. I'll update you tomorrow as to what is goign on...


I checked/cleaned the venturi tube/connection earlier when I was troubleshooting. No difference afterwards...

Roger,

Unfortunately, I have to report that nothing has changed in the last twelve hours. I have left the protein skimmer running and avoided "messing" with anything - but everything still looks as I reported above.

There are enough bubbles that I believe the Venturi to be working - and, as I said, I checked the connections when I took everything apart to troubleshoot.

Can you give me any advice at this point? I am leaving on vacation this weekend for a week and am troubled by the possibility that I won't have working protein skimming the whole time I am gone.

Paul
 
Can you provide any sort of pictures? Did you change any water, add any different food or additives? It is not unusual from my experience to have a skimmer not perform for as long as 3 days when a new additive is used or a fatty food is added or water is changed. It sounds like everything is fine, it does sometimes happen that their are not skimmable materials in the tank or their are too many fats to allow proper skimming.
 
At work now. Will try to provide a picture when I get home today.

No water change.
No new food.
No new additives.

I did change my activated carbon (old stuff used up, same stuff replaced it) two days before this happened. Skimmer worked that day and the next day.

And, as I said, I did stick my hand and arm into the sump in order to retrieve the suction cup.

It is hard for me to believe that there is nothing left to skim since there was so much output in the days prior to this happening.

It is reassuring that you say it seems like everything is working fine...would be nice to see a little bit of foam before I leave the tank in the hands of my friend for a week.

Paul
 
Having no skimming is not a life or death situation so I would not get overly concerned. Not skimming generally results in a slow deterioration of water conditions and excess algae growth but nothing catastrophic. It is possible the carbon was the cause. It might be worth reassembling everything one last time and being thorough and checking the air line nipple is fully inserted in the venturi. Also, keep in mind too much air can be just as bad as not enough so don't leave the venturi fully open.
 
OK. I'll do a take apart/reassemble one more time and make sure that the venturi (blue screw) is at least slightly closed.

I'll also try to calm down... ;)

Thanks for the advice. I'll see what I can do - I'll report back if something positive happens in the next couple of days or after I get back (that should be plenty of time for everything to settle out)...

Paul
 
Paul,

FWIW, my 9020 occasionally "stops" producing skimate. Usually after I have allowed my water level to go down to much by not topping off for a couple of days.

When this happens all I do is bring up the water level. Also, I take off the collection drain cups (9020 is a dual reactor unit) and clean them but let the skimmer run with the cups off for 30 minutes or so which according to the manual is supposed to activatea a self cleaning of the venturi. After I reinstall the cleaned cups, I usually have to open up the air screw a little bit to get the reactor to start producing foam again (which sometimes takes an hour or so) and after its foaming I start gradually dialing down the air over a couple of days to get dark skimate.

Hope this helps

As promised, here are a couple of pictures that hopefully will help with understanding my current situation.

The first picture is the tunze installed in the sump. Not sure if you can tell, but very little skim has been produced for the last two days.

The second picture is an attempt to show the water level and the (to me) copious bubble production - this leads me to believe that the pump and the venturi are operating properly.

Roger - does the water level/bubble production look right? If so, then it just might need some time to "right" itself.

Thanks.

Paul

It is definitely attached - just didn't get in the frame of the picture for some reason. It is working fine - steady, slow flow out of the top of it that comes down evenly around all sides.

Paul
 
So, Roger, you never answered my question. Does the water level and bubble production appear to be correct in the picture that I posted?

Thanks.

Paul
