Hey guys couple questions on the Dannco stuff.
On the ez-clean sys does the water enter from the top of the pump, ie is that black item in the pic the filter?
It appears to be pretty big and I'm concerned about it fitting into the filter box area where my pump is now.
Is there any benefit to the ezclean versus the standard Dannco venturi? Is there a difference in water output?
I'm assuming the venturi system is easily taken off the pump in the event you need to replace it?
Does the Dannco system maintain the circular water flow in a Super Bait Tank II (35gal) like I have now? That flow really helps keep bait alive.

Striperjohn. In the SBT-II, the way I've installed the Dannco is to just place it in-line to the output side of the pump, so you maintain the bulkhead and the directional fitting that is on the newer Dannco, so yes, it keeps the circular flow.
I know a tackle shop dealer in GA that is buying SBT-II tanks "bare" from Ron Vest and then he is putting the Dannco's and then selling them - he's putting the return much lower in the tank to allow for more dwell time, and putting the Dannco directly as a bulk-head fitting on the bait/filter divider wall without using the directional return fitting that Ron uses on his newer stock SBT-II's. As long as the return was placed off to the side I would think it would still generate a circular flow as the flow hits the opposite, curved side of the tank. However, in some ways a fully circular flow is not perfect in the SBT as poop and whatnot accumulates in the "dead water" middle area which you have to stir up to get back in the water column so it gets filtered out.
All the Dannco EZClean is, is a self-contained pump & Dannco venturi aerator with a small filter. Probably good for use in a boat livewell or a large bucket / homemade tank. Yes, the water would enter through the top cylinder (through the screen mesh), go through your filter material and then be ejected out through the pump then venturi. I would worry about how quickly that screen mesh is going to clog up with shad slime however.
No reason you could not plumb the output side of that venturi to an return in your tank if you desire. On the SBT-II, certainly no need for this - just put the Dannco on the output side of the Rule pump before it returns through the bulkhead as above.

Striperjohn, I have a 35 super II also. Mward showed me how to add a Dannco Venturi inline. See Picture below...pretty simple and works awesome! Much better and quieter than the Keepalive aerator that came on it stock.  |

Thank you guys. That's kinda what I was thinking but not sure. I guess I need an 800gph pump vice the 500 for the Dannco right?

Thank you guys. That's kinda what I was thinking but not sure. I guess I need an 800gph pump vice the 500 for the Dannco right? nope - I use a 500 gph, and I think my venturi is the model that the website indicates is for the 800 gph. The Dannco puts out an insane amount of air with it as is - no need for the 800 gph to have that extra flow to beat up your alewives and small shad. I've actually considered changing the 500 out for a 300, and putting in a 2nd 300 on the other side- that way when keeping alewives outside of the summer months when more air is important, I could run one just one 300 gph and have a little less current on the baits - and/or run the 2 300's as an insurance policy in case one pump died overnight...... |

GOOD LORD! I have been analyzing my bait tank today on yet another one of my thought adventures! I have considered the SBTII but screw that, I want to modify! With this being said I have examined several homemade solutions on the Internet such as 3 stage filtration hooked to bilge pumps, etc. and of course I was led to the EZ Clean system by Dannco. After a little research...you guessed it..I'm back here reading what Mward and Bentrod know. Freaking insane! Can I have a hug?  So here are my real specs. Examine pictures.   The tank is 30 gallons. The inlet is halfway up the tank and has an air intake (You can see the air intake in PIC2... black wire looking thing). Water comes in through a half inch threaded male that is in a corner of what should be an oval (SEE PIC1). There is a drain on the bottom in the middle that uses a simple rubber thing with ribs. And the overflow has a removable plastic screen on it and is about 3-5 inches from the lid. Currently, if you turn off the pump, the water will drain back down to the inlet height unless you close the valve that is in the bilge compartment. The system works good in the Winter, but I am thinking once I go closed loop, I will never go back. Thus, the existing pump that is in the bilge compartment will only get used to fill the tank when temperatures permit. I also envision filling up the tank with my raw water wash down (this is the pump in the second picture) when the temperature permits or I could use a 5 gallon bucket and some ice and a thermometer to introduce some freshy-fresh from time to time utilizing the overflow for regulating the volume. So now what should I do? I have no problem drilling a hole into the bottom side to collect water. As you can see in the second picture, I have a nice amount of room to build a masterpiece and I have a deep cycle battery that is awaiting. I am thinking the bottom would be good for removing ammonia? I will then need to draw this water into my filter. I like this filter idea using a three stage filtration system. www.youtube.com/watch?v=ectupxqftWIAlthough I am still confused at what type of pump this guy is using. Or I could just have a big 4 inch pipe that collects water and use a bilge pump to force water through a filter of some sorts? I assume a bilge pump doesn't need pre-filtration being that it doesn't have it in a nasty bilge compartment? So then there is the issue of where to reintroduce the filtered water and how? I could plumb into the existing inlet and take advantage of the existing air intake. Or..I could drill another hole anywhere including above the water line and create a long tube with holes that sprays water in. Or I could use the EZ CLEAN system if only I knew how it actually worked?? It appears to have everything I need excluding the connections to the tank? And finally, I am a bit concerned about the area in PIC1 that ruins the oval shape of the tank. I have noticed that my little buddies like to nose up to the intake from time to time. Is this a big problem? Should I baffle off this area? Maybe this area could be my filter and pump compartment via a baffle? Or maybe I should overlook this issue in the name of KISS? I cant wait to hear what you think! |

The first and easy mod is to put an in-line or bulkhead Dannco on the output side.
Then the question is how to deal with filteration. Ideally you want to draw down from low in the tank to get sediment, scales, etc. That should make it's way into a filter and then be returned to the tank. Question is how to was tilt access filter material to clean.
Take a look at the greyline bait tank website and their filter system. I don't love it but it may be something that could be rigged inside your livewell for filteration and then use your existing recirc and a dannco for aeration.

When I think output, I think overflow. Water going out of tank. Input is intake or water in. So do you mean put the Dannco on the input line? Perhaps I don't have an output as you are thinking because I am water in and water out versus closed loop? And are you defining my existing bait well pump as a recirc pump? Secondly, what are your thoughts on where to reintroduce the water if creating a closed loop? Bottom, middle above water line? Many ideas on this out there. Finally, from reading your posts and thinking back to my water treatment days, it seems that my screwed up oval shape may be a good thing for reducing dead zones in mixing. We would put baffles on circular tanks to get better mixing of chemicals. Thus, this shape may actually lead to better mixing with minimal wall bumping especially if the circulation forces the shad to swim counter clockwise. In other words, maybe the design of the tank requires that I use the existing intake for my closed loop water inlet? Or do the shad swim against the current in a tank? Dammit...this is too hard! I just need to get a SBTII and forget this. NO!!!!!!  |

You're in the same situation as me. On my old boat I had rigged up a PVC filter box and intend to do that on my new boat too. In my old boat, I put a screened thru-hull low in the live, then a hose over to a thru-hull mounted up high in the side of a vertical 4" PVC with a cap on the bottom and a cleanout on the top. I mounted a thru-hull livewell pump out the side of the PVC near the bottom and filled it up with polyfill. The output of the pump then went to a directional thru-hull in the livewell. I based it around the Keep-Alive recirculating system the last time, but when I get around to it this go around, I'll use the Dannco venturi instead. It really simple if you have room for it. The only gotcha is that you have to either fill up the filter with the cleanout off, or provide a vent to above the water line. When doing a filter box for the built-in livewell like this, you can't just have an open-top filterbox like on a real bait tank since your waterline is usually too close to the top of the tank. It has to be watertight or it will slosh into your bilge. (Sorry I don't have pics of my old install) |

Yam - by output side I mean the output of the recirc pump where it returns to the tank.

It seems the screen would keep big particles inside the live well? I assume this screen would be on the inside of the livewell and that you connected a hose to the other end of this fitting that went to your outside-the-tank PVC thingamajiggy? Secondly, did you consider the activated charcoal three stage filtration idea (link above)? I cant fathom a better way to remove ammonia build up which seems to be the third worst enemy of shad. The first two being temperature and lack of O2. Does the poly have an affect on the ammonia? Finally, me and you need to collaborate for sure. I'm on this big time now. With your experience and my tenacity, we should come up with a killer solution that is elegant and will be a place that all of Bentrod's shad will want to hang out versus his dirty ass boat! Perhaps you could create a hand sketch of your solution and post it? |

The screen keeps little ales (dead ones when I find them) from clogging up the intake. I don't know.... I never try to keep bait overnight so just the polyfill seems to be good enough. They are red-nosed by the end of the day though. I dunno... My solution is more of an hourly rate motel vs his luxury hotel in his shed already ahead of you [/quote] |
