UV Help

[Cmajor]

I have a 25 watt Aqua Uv on my 150 gallon pushing 400 gph. I am hopeing to use it to help clear up some dinos and cyno. Is 25 watt undersized or will it work? Also am i running the correct gph of water through to even help?

I have the same UV on my 125g. Aqua Ultra Violet says we need 400 for parasites and about 700 for algae.

Im running at 400 now and it does not seem to be doing anything. So should i increase it to help out. Its been running 2 weeks now.

Yes. Need to go at least 700gph for it to help with algae.

Officially dinos are algae I believe and algae needs multiple tank volume turnover an hour but from my research dinos need a much slower turnover.

When I had dinos my turnover was around 1-1.5 tank turnover per hour, it did the trick within days.

Yes. In the past I have always thought slower was better. The thing about Aqua Ultraviolet is they want you to burst the uv in gph. I look at their charts and im like who runs a return with so much gph? They base it on the amount of time the water gets zapped. Other brands have slower turn overs. I just run it at around 400 and I dont have a problem with ich outbrakes and/or algae. Just the weekly glass scrapping.

Ok. Thankyou
