170 gal Peninsula system

[Peppie]

Looking for some input on this design. I want to have a 3 sided weir on this tank.
The front and back weirs will drain into the right side weir and flow into the overflowbox on the right side of the tank. The box will house a Bean Animal drain system. The over all height of the tank will be 30''. I will keep the water level 1'' below the top rim.
Please let me know if this will work for the flow of water to get to the overflow box.

While I have the attention of the flow masters here. Can you recommend what type of external pump would be best for a closed loop system. I will want to run 2 pumps for this system. I would like to have one inlet (feed) for each pump. And 4 returns for each pump. I am thinking about around 4000 to 5000 gph per pump.

Yes ? No? am I way off base ?

Reeflo pumps are good for closed loops or you can use pressure rated pumps with penductors

INteresting idea Pep. I am going to put some thought to it today while working.

My first thought was " those side overflows are going to be an algae haven" The reason why is the water time flowing over a shallow area. Your going to see a lot of growth in that shallow wier setup running on the sides. I would suggest a black out top for the two sides. Something that will cover them and block all light from entering. IF not, they will end up working like agae turf scrubbers. This is not a bad thing. You could also lay screening in the wiers so you can harvest the algae out of the system.

For a closed loop pump at those rates look into the dolphin ampmaster series. I used an ampmaster 3000 for my closed loop with great sucess. It pumped 3000 gph with no head loss. You may get away with an ampmaster 4000 for your setup.

These are low energy preasure rated pumps that are perfect for closed loop designs. Big fan of the ampmasters here

Look forward to discussing this further tonight after I have had some time to thing on the design some more.

Some how I knew you would be one of the first to reply Frankie. Yes I have thought about covering the weirs to reduce the algae growth. The weirs will be hidden from sight with a face frame. Thanks for the recommendation on the pumps. I will do some research.

Titan, thanks for the reply. I will also research that type of high pressure pump.

Hey Dave, looks like another fine project to get yourself into. With the 3-sided coast-to-coast-to-coast-to-coast design it would/could be very effective to at least one major return in bottom center of tank pushing all detritus up and out of DT. I have a Dolphin Super Amp-Master 4300gph you could plumb in.

Cheers, Todd

Perfect Todd, I will take you up on that offer. PM me what you need for it.
I have got a few more different ideas for this build. Once I get all my flow issues ironed out I will be able to order the glass

That pump will be perfect. Sorry to be the first poster Peppie! I pay special attention to you since your the last poster on my thread. lol, dont worry, im not falling behind, just letting you all catch up to me

Now a days it is hard to devote a lot of time to a hobby that is strictly a luxury. With work always getting in the way. And there is always the honey DO list.
Not to mention the kids need to go here and be picked up from there.... on and on and on.

Back to the tank. I think I am going to reduce the length of the weirs on the front and back to half the length of the tank. I am hoping to hide a couple of the return lines in there also (one per side). I think the weir being 3'' tall in can run some 3/4'' pvc close to the top of the weir (keeping them out of the water flow of the weir). I like your idea of blacking them out. I think I can use black acrylic to build them, and make the lid removable for mait.

 

[eww]

I think this is going to work great as designed Dave. You're getting better at this. Only one design submitted so far. What, are you trying to avoid the triplicate paperwork of change orders this time?

I also agree with the black-out tops for the overflows. I am considering making a couple of lids for for the 180 overflows to keep any residual light out and believe it or not we are finding snails in the sump. It would also keep any adventurous fish out. Were you talking about running 2 pumps with 4000-5000 gph per pump or is that the total for both? I could see that on a CL but a return coming back from a sump it might be a little much IMO. Why would you go Bean Animal as opposed to a Herbie? Herbies eliminate the whole air tube down the drain thing and they are dead silent (I understand BA's can be silent as well). You also get a faster drain flow with a full siphon in a Herbie. What size drain pipe and return pipes are you thinking?

 

[Peppie]

Hey Eric,
I am considering black acrylic for the whole weir system including the removable top.
I will be using a dolphin pump Todd offered up for the Closed Loop it is rated 4700gph. I want to split that pump into two lines to run a pair of 1'' squids rated 3500 gph each.
I would like to keep the sump return pump to around 1200 to 1800 gph and either throttle it back or have the option to run other equipment off of it.
I am pretty firm about using the BA I like the design and the redundancy. It will be 1 1/2'' drains that should handle up to 1800 + gph easy

I am not worried about the submission of ANY paper work on this build. I am going to do it like you did.. JUST STAMP IT APPROVED (MYSELF) LOL

 

[eww]

Self promotion to inspection manager... Gotta love it.
I happen to know someone with a couple of 3/4" seaswirls if you were wondering... Just saying...
As to the BA... You always have been stubborn
If you are planning on throttling back the return pump from the sump just make sure it's a pump that can be throttled back without putting strain on it or overheating it. I think there are some pumps that are good with it and some that aren't. I know the Reeflo we are using now and the Eheims we have used in the past don't mind being turned down. I'm not sure about others though.

 

[Peppie]

Thanks for the skinny on the type of pumps that can be throttled back. I will keep my eyes peeled in the want adds for a good price on a Reeflo

I am sure some one might want your seaswirls some day. But today is not your day. LOL

I would really like the inside of this tank to have great flow without the use of any powerheads.

 

[Frankie]

You can throttle back all the ampmaster pumps without damage to the pump. Just be sure to put the gatevalve on the output side of the pump. Not the intake side.
