So I installed the Dannco thru hull. I really liked the existing SBT fitting. However I had the Dannco thru hull, so I used it. Air just shoots right in versus going to the side.
My question concerns scales and other debris. It seems that a lot of debris and especially scales from herring are collecting at the top versus being sucked into the filter. Is this normal or could it be that the old fitting circulated the water better? I'm also concerned that the blast from the thru hull is hurting the bait and thus removing more scales. Keyword concerned.
Keep in mind that I am still getting junk into my filter. However, I did not realize I would have to use a small net to skim the top every 20 minutes or so. I have also noted that the more I open up the air valve, the more the foam and the tendency for junk to get caught in that foam.
Thoughts?

Yam I have a 20 and 40 SBT and had the same experience using the dannco supplied through fitting. I called Dan and he said he did a study and determined that the SBT 90 degree fitting limits the amount of oxygen. I didn't like the circulation either so I stayed with the stock 90. The better question for Dan would be "how much oxygen does the tank really need?". There are problems with too much and quite frankly in the summer oxygen is probably not the biggest contributor to unhealthy bait.
Bottom line is that I use his supplied tubing and jam it on my rule pump and keep the 90 in the tank. I would be curious to see if anyone else using the dannco thru fitting have seen a much better result.

I removed the 90-use a curved hose and use a 500 pump. If you are using a bigger pump that may be your problem. Could be way too much pressure out. Most if my scales go to the filter.
Yam in the hotter water the will lose much more scales also.

I've got the same problem with a 50 gallon creekbank.

Thanks everyone. I experimented today and rigged the thru hull Dannco to the stock thingy that shoots water to the side. No doubt, the o2 produced is insanely better than the stock aeration. And the side thingy just simply makes a calmer environment. Thus, my thought is screw the thru hull Dannco and get the inline Dannco. My buddy has this configuration and he never has to skim his surface..just a few sprays of defoamong agent maybe twice in a 5 hour period.
Live and learn.

Final solution. If you have a thru hull dannco, use the remaining threads that are exposed to the bait side of the tank and screw on a pvc end cap that has a hole drilled into the side. I created 4 caps, each with differrent sized holes which dramatacally change the flow in the tank from nothing (big hole) to very swirly (little hole).

Pics? How much of the water flow are you impeding with the PVC cap? I'll take flow over swirly....  |

Exposed threads from Dannco thru-hull fitting  Modified end cap  Installed end cap  I am with you, too much swirling is probably not good and may limit the amount of settling of debris that can get sucked into the filter. I guess there is a happy medium that needs to be achieved between mixing the water and settling. Not sure on where this medium is. However, I am quite sure that blasting the tank with a direct flow not only wears the bait down, it makes the debris rise to the top rather than get sucked into the filter. |

 thanks now i'll show you mine Your venturi butts right up against the wall of the SBT where mine needed the PVC threaded piece to go through. I like yours better because I dont trust the press on fitting between the through-hull and the venturi. Did you somehow modify yours ? So the one you received has threads on the venturi itself ? |

He's got the "bulkhead" version of the Danco Venturi. It's not on the website if I recall. I'd get that one too now if I were doing it over as it gives a little more room on the filter side and one less clamp to fall off and let you down overnight the morning of a tourney with dead bait - not that I'd know anything about that |

Why not put the bulkhead coming out on the bottom of the tank? Then you don't need directional flow and it will "stir" up any sediment that settles on the bottom. |

Tyler the only thing that I wonder about that is if there will be enough static head to limit the pressure of the pump so that it will pull air through the venturi hose. I know that sometimes if there isn't enough static head the pump will just push water up the venturi rather than pull air through it.
