UV Installation Question

What type of overflow? Full siphon ?

It is the small bubbles that cause the most problems. If you have full siphon and an oversized UV-C - it maybe works - but it is not optimal.

Sincerely Lasse

It is an ELOS Quiet Drain. I assume it's a full siphon but it gurgles and I expect some bubbles are making it down into it. JP

I am not familary with that construction - but if you try to adjust it to be as silence as possible - you will have a better result - it is the bubbles that create the noice. If you do not have the manual - I found this

I figured i would piggy back of of This thread because I have uv installation question. I recently just picked up a lifeguard ql25 off a fellow reefer. My question is should i feed from my overflow or should i ir jade a separate pump such as a mj1200? I have about 700-800gph from the overflow with a return pump set at same rate. If I connect from the overflow should the return of the uv be placed in the filter sock, skimmer or return chamber?

I have mine separate. I have a pump on one side of my sump and the return dumps into the return chamber.

I thought about this. I don't think it's the best approach but can't remember all the reasons why. Off the top of my head you'll get particles floating through and I know you want to keep the source water as free from detritus and sand and stuff as possible.

Yea I decided I’m going to feed a pump from the skimmer to the uv and the return from the I’ve into the return chamber

Older thread but rather than starting a new one... hoping those of you with experience with this could help and/or offer advice... @Jrod381 @Lasse @Balanje

Looking into UV sterilizers to help with Ich management primarily. Have a newly running mixed reef. Like everyone Im tight on space and don't want to mount on the exterior of the stand. System is 900 liters (243 gallons). This RedSea Reefer has a separate sump that is connected to the main sump in two places (in from Fuge and then out to skimmer chamber). There isn't good flow through it so I added a small pump to keep some water moving. I planned on using this as a frag tank (thus the light). My thought would be to put a Sicce 1.5 pump in this compartment because there is plenty of room (and it would increase flow through this compartment). The UV sterilizer would mount on the side wall. Then id run the out line to either my return chamber OR my skimmer chamber. Water coming into this frag tank chamber does come from my Refugium but it seems like the best clean water source. I have a screen over the inlet so chunks of Chaeto don't enter but I suppose some pods could. Most of the water from the Refugium goes over an overflow into the skimmer chamber. I also have a Oxydator in the return chamber. Photos to help understand my set up. Appreciate any help! Thanks in advance.

Looks like you are mapping out a Vectron UV. I have a Vectron 600, the Sicce pump isn't going to get it done. I run 300gph through mine. I bought a cheap Jeabo DC so I can control the flow rate

Yes the Vectron 600. I was basing the Sicce 1.5 pump choice on the OP using it and was getting 240gph. Its rated for 358gph (which I understand they never achieve). But Im open to what is recommended. DC control would be nice especially if I ever wanted to speed up flow. What model did you go with?

I originally bought a small Eheim pump (I think it was also rated for around 350) and used 1/2" tubing. I was getting like 150gph. I think I bought the Jeabo 1200 (I can confirm later) and used 3/4." I have it on setting 6 of 8, and I am almost exactly at the recommended point (200 gph??). It's been a long time, lol.

So just an update to this thread. Ended up running two Vecton 600s in line. Closed loop to and from the display tank directly. Used a platinum blue 800 pump (which is completely silent and an awesome little pump and fully adjustable flow). Running at about 275 GPH at the moment.

The install was a little tricky as I installed into a cabinet on the back side of my tank (in another room).
