I just went back and counted... four different people said "That is not a closed loop", and most did not post anything more valuable to the thread, hence my fustration. Again, I am not griping about people criticizing my idea, just people who want to debate whether or not this system has a closed loop of any kind involved. I have no interest in that argument.

Your initial question was Can I run my return and closed loop off the same pump. Their answers were perfectly correct. THey answered that question. No, you can't because then its no longer a closed loop, and no longer functions like one. It is just an overcomplicated failure prone return. THe whole point of a closed loop is that there are no outside forces on it. No head, no chance of leak, etc. Closed loops shouldnt even be in this conversation.


I know this sounds harsh, but you asked a question, and they answered that question accurately, and succinctly.





A better solution to your High flow tank, low flow sump, multiple outlets desires would be a small pressure rated pump with eductors.

Or a CL and a return.

sorry rich i got off the subject. lol

you could also divide the sump into two areas a high flow area and a low flow area.
each area fed by a seperate line

Enclosed Sump

Enclosed Sump

Iââ"šÂ¬Ã¢"žÂ¢m new to this hobby and was contemplating something similar.
Since you all have a lot of experience with pumps and all I was wondering if you could look at my idea. Iââ"šÂ¬Ã¢"žÂ¢m leery of the HOB overflows, pump and open sump due to flooding concerns. Leaving my HOB skimmer on the tank, why could you not use an enclosed sump (no air inside) with a SCUD? This would be similar to a large canister filter.
All comments appreciated! Here is the idea:

and the top view:

If I screw this up just look into my photo gallery.

Thanks for looking,

I don't understand the purpose of putting the SCWD in the enclosed sump?

You could save yourself some money by keeping it outside of the sump. You wouldn't have to buy/use so many bulkheads.

My thought was to cause some wave action on the return with two lines instead of just one return line. The SCWD in the sump would contain leaks, salt creep and possibly keep the SCWD quiet (I do not have one but had read they were noisy).

That does make sense then.

Like you already said, it is just like a canister filter and I don't see any reason why it wouldn't work. But it really wouldn't be a sump if it worked like a canister filter, it would just be a DIY canister filter.

I'm not trying to burster your bubble or criticize your idea either.

ive seen a similar design but much more simple. it was for a nano tank and was made out of a canister filter. everything was self contained even the light for the refuge. the advantage with the design is it was able to be opened for regular maintenance. i strongly suggest that you start a new thread. i am sure you will get plenty of readers and replys. something like "sealed self contained sump" or "canister filter refuge" would make a good title.

 

[jmait769]

No I understand and I want the criticism before I spend money on this idea so I really appreciate your input.
Like you said this would be an oversized canister really but I wanted to add water volume and prevent flooding. With this enclosure do you think the refugium area is viable? By this I mean would algae grow in that area and remove nitrates or is it just a waste of space?
Iââ"šÂ¬Ã¢"žÂ¢m not married to this idea so again all comments welcomed!!
