Sump Help
 
Here is a very rough scetch. I am looking to build a sump right now there is a wet dry filter with floss no bubble trap or filter sock or sand. Here is my idea can you offer any other help. This is for a 75 gal reef tank.

Seems pretty decent. I would use pvc for the return line and the intake line.

Rogergolf66 04-09-2007 07:11 PM

Thanks

PVC not hoses? what about the tank it self? Glass, Arcylic, or rubbermaid? lol.

Glass. The others will give a little. Glass wont give under the pressure of the water.

I made some changes. the water would have been going through the refugium to fast. what about this. also I am using a double over flow now.
the DSB will still be in the refugium I just forgot to draw that in.

Fantastic.

Not fantastic. Roger, If you want to do it right, have your return in the middle, split the over flow to either side, one for the skimmer, the other for the fuge. that way you're not skimming out the bugs from the fuge (which you'll want to be carried up to the main display for live food suppliment, and youre not skimming out the nutrients that feed the fuge life.


Refugium>Skimmer>Return: Worst option. Skims out the copepods, mysis, and other bugs residing in the Refugium before they can be carried up to the display tank where they would have been beneficial in replenishing the live food supply, as well as the consumption of detritus in the tank. Defeats the purpose of the refugium (aside from the Nutrient Export via Macro Algae cultivation)

Skimmer>Refugium>Return: Better option. Skims out food for the copepods, mysis, and other bugs residing in the Refugium

Refugium>Return<Skimmer: Best option. Allows tank water entering and exiting the refugium to be unaffected by the skimmer.

I wish someone had been smart enough to point this out to me when I was asking questions.

Rogergolf66 05-24-2007 07:52 PM

Well thank you my question then would be well how do I slow the water flow down enough. MY pump will be 1200gph and that is way to fast for a refugium?

Wait what if I did this?http://www.fishforum.com/userpix/647_File0012_1.jpg

Not true. I used to believe that.

We can argue as much about this as lighting.

I used to believe the same thing.


I dare someone to show me a skimmer cup full of copepods.

I've found about 3 in 3 years.


The little of the benefit that may be skimmed out is such a tiny fraction as to not count. It matters little if the water exiting the fuge goes into the skimmer. Your tank produces plenty of pods if set up correctly.

Now for my final argument and then I'll leave you to slam my response again, How many pods do you think survive the trip through the blender known as the return pump? It helps to think it all through before you respond.

You can build a sump that has the skimmer chamber on one side, the fuge on the other and the return pump in the middle, I've seen a lot of headache go into keeping the water level correct in those set ups. I won't say that is a bad way to do it, unlike my friend above. Both ways are great.

Remember that the copepods IN the fuge are the beneficial copepods, they are helping to break down excess large particulate matter, once they leave the fuge they are only considered a food source, be it one that is whole and swimming or one that is pureed by the pump. There won't be thousands of them pouring over and into any other chamber as they typically stay attached to the macro algae and rock work, just like in the display. So the very few that do make it over and the one a month that might get caught in the skimmer do not matter.

Any takers?

SKAustin 05-25-2007 07:22 PM

okay CRM, I have a Q or two for you.

If your skimmer is doing an efficient job, then the skimmate it's producing should be a dark brownish greenish somewhere inbetweenish. How might one go about counting the bugs that make it into the skimmer? and how would one go about standing the stench long enough to count past the number three?

If "the blender known as the return pump" were to effectively puree any copepods inadvertently taking the trip up to the display, then would it not stand to reason that the skimmer pump would do the same? that being the case how would you expect to see them in your skimmate?

With what logic would the placement of the return chamber have on the procedures, methods, and overall ease of water level maintenance?

With all due respect, I agree with one thing. It helps to think it all through before you respond.

On a final note, I did not say that the other two methods were not effective. I simply stated that, some options were better than others.
