Ok so after finally having it out with my skimmer and doing tons of research online I finally decided it was time to raise it way up and see what happens. But what I am a bit unsure of is if the bucket logo and such will leach into the system. I did clean it up with vinegar and water really well. Here are some pics the problem I was having was that the skimmer would produce a huge foam head and hardly anything would spill over. Some times however it would work flawlessly as it did when Todd adjusted it to begin with. After battling with it for so long I am thinking that the problem never was the skimmer but something wrong in the tank. I don't dose anything and my bio load is too low to cause anything too crazy.

As you can see from the pictures everything looks to be running normally, but it always does after I clean it then shortly after (8-10 hours sometimes less) the giant foam starts. So we shall see any ideas what may cause this?

sounds like there isn't much to pull out of your tank. try raising the water level slightly and check it tomorrow. keep doing this till you are getting a medium skimmate in the cup. Not too wet and not dry foam.

Thanks Jig you don't think that the paint might leak off of the bucket? I am a bit worried about that.

Yo Tad, you might want to try cleaning the pipe in the cup and the inside top of the skimmer body with a clean rag. It may have a build up of film on it that normal rinsing can't remove. That also will inhibit foam production/height.

On the bucket, maybe saw off the areas with the paint and just leave three legs. It's going to accumulate stagnant water under there and cause other problems too.

A couple thoughts are it looks way to high in your sump. I've found that having the skimmer in the right depth of water is a big key to performance.

Are you running an ATO that keeps your sump at a constant level?

If you are topping off your sump manually the fluctuations in the level of the sump will not let the skimmer work consistently.

I doubt the logo on the bucket will have anything to do with it.

Water level looks way too low to me. 9-10" is best.

I didn't think about the stagnant water that's a great point thanks. I don't have an ATO yet but the skimmer is in the first chamber so the level is constant. After about 5-6 hours I just checked it and there is a huge foam head already. It's almost as if there were some laundry soap in there. I will try to post up a video tomorrow so you can have a better look. This is the highest I've tried it so far I tried with the level all the way to the top of the first chamber and then halfway raised up and now this. I always get the same results soapy type foam. Thaks for all the help guys I'll post a vid tomorrow so you can see the crazy foam.

Are you talking about the water level inside the skimmer or how far the skimmer is submerged in the sump. If you've always had the skimmer sitting on that bucket and tried to adjust the water level inside the skimmer I don't think you're going about it correctly.

Raising or lowering, in your case, the skimmer in your sump may be the first step in solving the performance problem. As Murph said the bottom of the skimmer submerged at least 9 to 10 inches below the water level works for most skimmers. Yours look to be no more than 6 to 8 inches below the water surface.

I have my ASM mini G in about 12 inches of water... I have been playing with height and found this is the best for my skimmer. I think these guys are right and you really need to get that skimmer down further in the water.

Ok so I am going lower the skimmer down about 4-5 more inches so it will aprox. 9 inches deep. But on any height as you can see in the video it makes this crazy foam no matter what setting it's at and if it was any lower it would produce nothing at all. I am convinced that it is something in the tank I cleaned the skimmer before I set it up yesterday and it performed fine for a while and then this. It's almost as if it has soap in it. Which I am sure could not possibly be the case cause I use vinegar to clean everything.

Have you taken the pump apart to make sure it's clean and the needlewheel isn't broke? I agree with the skimmer being in about 9" of water. You just might have to raise the water level inside too.

Yeah I checked the pump and cleaned it. I bought a new pump for it recently and the old pump made it perform the same way. I really think that it must have something to do with the tank although I cannot prove that. I am gonna set it down in to 9" tomorrow and try again and clean everything again. But I always seem to get this crazy foam for some reason.

You might try running some chemi pure and phosguard in bags. The skimmer in our 72 does that when we dose with something lik chemiclean for cyno and also when we do the heavy vsv carbon dosing. I'm not sure if it's the treatment itself or the resulting bacteria and whatnot that cause the foaming. Try the suggested adjustments, but you're probably right. It might just be some level that is off in your tank and the skimmer is telling you it needs adjusting.

sometimes you gotta let it wet skim just to catch up to itself. I would make 5 gallons of fresh saltwater and just let it wet skim away and keep topping off with SW till it settles
