Can i run a closed loop in dt without adding a pump in the dt?

[PegasisR]

As title states. Would that be possible? Needs are for uv sterilization

Do you have dual returns?

Do you have dual returns?

unfortunately not because its a rsr 525xl (herbie)

Only think I can tell you is put another pump in the sump and run a hard line from the pump to the UV and over the back or side

where would that input go? in the skimmer section and output into the return chamber?

 

[Hydrored]

You can do that although it’s not optimal. Your best bet with UV is to take the water from the return section and return it back to the tank. This would take running some additional plumbing.

Would you happen to have a diagram? The brs video doesnt really give/show a concise way to do it

No clue what you mean by the thread title?

Just meant if there was a way to have the pump outside of the tank but if you have a diagram on the best way to install a uv sterilizer, that would help immensely!

A closed loop is a pump circulation circuit where the suction and output are both in the display ..... so, yes, you need a pump to move water through the circuit. Whether that’s a good way to provide flow for an UV is a different question. I don’t think I’d do it personally .... adds unnecessary leak opportunities. I run a closed loop on my tank and it is solely for circulation, no equipment in the circuit .... other than the pump. I actually run my UV off the siphon drain, though that requires a bit of pre planning.

Any other ways to run it properly?

I see you’ve got a couple of threads on the same topic. Why not just plumb the UV into the main return? The other option would be to use a dedicated pump in the sump. As long as the output from the UV is close to the suction of your main return you’ll minimize any recirculating though the UV.

Yes i do, mainly because im really confused aswell as unsure of how to plumb it correctly (especially the dedicated pump way). How would i plumb it into the main line? Where would i run the dedicated pump from if i did it that way? Sorry for so many questions but this has got me stumped! I really appreciate the help aswell!

Go from your return pump into the UV, out from the UV to your return line. I

Will there be any dwell time issues and maybe the return being too fast?

You need to figure out the gph you will need to put through the UV for the purpose your installing it for.

It will be a useless tool if its not correct.

Is this for bacteria and algae or is it for fish parasites?
Then you need to know the correct amount of flow your UV recomends for the job you intend it to do.
The flow rates for either of these is extreamly different.
A single UV will not accomplish both.
Tapping into your filtration pump and plumbing will most likley cause you more issues than your atempting to fix.

Every tap into the return line reduces flow for everything in that system.
Just the nature of the beast.

I would run a seperate pump and plumbing for the UV.
Preferably a DC unit that you can dial the flow for optimal flow control.

This will be for algae and it's the aqua uv classic 57w (can't find how much flow for algae ) would you be able to show me how I could run it through a separate pump? Maybe in a sketch because I'm stumped how the water would return to Dt

Add another return pump into the same return section, plumb the new return pump into the uv, from the uv plumb new (secondary) return lines up the back wall and over the top of the aquarium.

 

[Chefwheredyougo]

Excuse my poor drawing, its 4 am and I'm on a phone lol. Two bottom left dots are return pumps, green line is the returns, red is drains and drain lines, big middle yellow is the UV. Its not to scale, its super basic

Perfect, thank you! Also Just for understanding, how would it work if running through a manifold?
