UV Steralizer setup help?

Greenstarfish03 · Feb 15, 2020

I have a 100g dt and and about 50g in my sump in thr basement w/ about 16 foot head from thr sump to the display. Im running a reeflo Goby return (sister of the hammerhead) at my head Im probably getting between 1500 and 2500 gph return.

What flow do I need to run my coralife 36w uv at to best deal with Ostreopsis? Should i try to plumb this in to my return in the basement, a seperate pump into the basement sump or a seperate pump directly to the main display? If anyone has any info on setting up UV sterliazers in a similar system I would appreciate the link. Thanks

I also have a few maxijets pumps, and a mag drive 9.5 I can use as well. I want to get this running asap even if I have to set it up in a temo basis.

It is best to plumb it directly to the display. Best to use a dedicated pump just for the uv also. You should look up the flow rate but I think it should be around 700gph. Better double check that though.

The manual for my uv says 290 gph for parasited, 680gph for alagae so 700 seems about right. The mag 9.5 I have is rated 950gph so that seems like a good fit bc I will have some head loss and I have the pump. Do I need to get a single state prefilter and then just plumb that and the uv below my dt?

You dont need a prefilter and you can plumb it whenever you want as long as the flow out is the correct gph. It is more effective if the water comes from and to the dt, not the sump. As long as you do those things you should be good.

Any thought on how I avoid hoses hanging over the back of the tank if i plumb it to the dt? Currently its clean just the return.lines in the overflow and I want to avoid making things a mess.

What is the correct flow out? 700gph? I have no way to know other then go off what the pump is rated for. Is that close enough?

You could use hard pvc using 90s over the back so it looks clean. You could also set it up to only run when you need it so maybe you could get away with ugly if it is not going to be permanent. You need to set it up with the plumbing and pump outside of dt and let it run for 30 sec and see how much water is pumped out and mutiply by 120 for gph. You need to be fairly accurate with the flow rate or uv sterilizers are useless.

So i assume i should use a valve out of the pump to reduce or increase the flow? Any thoughts on sump pump examples? Im trying to use something I have without having to buy a new one if possible. It seem slike any pump that hits 2 or 3 hundred gph at whatever head loss should be fine. I was told in the algae thread that to combat dinos I should sit closer to the parasite flow then the algae flow rate. I think I only want to use this as needed for now bc Im generally against doing anything new that I dont need to do so im leaning towards mounting it under my dt w/ temporary plumbing and running it for a week or until my issue is resolved then turn it off unless I meed it again. I just want to make sure even a temp setup is right.

You need a valve to be accurate. You should check out the dino thread or search for best results with uv and dinos. I have not heard to reduce flow that much for dinos so do your research. Dinos multiply kind of fast so I would think faster flow used for other algaes would work better but I am not sure.
