Uv sterilizer flow...

[som857ee]

The secret key to success with UV results is to make the exact flow rate in the UV sterilizer unit. This is a Quotation from a well-known saltwater mentor in the reef hobby. In the theory is easy to do. but in reality is far from doing in a home aquarium. What is your approach to make it more easy and possible in the home condition? Give you an example... You go to the store buy a UV unit..open the box...and as it says on the box by the manufacturer: the need flow rate is 1000 for maximum results... Buying a 1000 gph powerhead...but what promise me that is really 1000 gph pump? And what promise me that is really what passes through the UV unit for a period of time?

It depends on what you want to accomplish. If just clearing algae, then Being too accurate won’t matter as much.

For bacteria and and parasites we care about, none of the hobby grade units on the market seem to deliver the levels of radiation proven to actually work. Manufacturer numbers are based on freshwater research and hope that a slight increase will work in saltwater.

The key is get the apex flow monitor and a valve so you can set it exactly what you want

I'm curious where that information comes from.

I'm curious where that information comes from.

Not many studies on successful use of UV on C.irritans, most research was done on the freshwater variant.

“Use of ultraviolet (UV) sterilization to kill theronts
has been suggested, based on research involving Ichthy- ophthirius multifiliis (freshwater “ich”). The recommended UV dose for Ichthyophthirius theronts is 100,000 μWsec/ cm2 (Hoffman 1974). However, UV doses required for Cryptocaryon irritans are anecdotal or extrapolated, and range from 280,000 μWsec/cm2 (industry numbers) to 800,000 μWsec/cm2 (Colorni and Burgess 1997).”

Thanks. I'll read it.

Since actual flow rate is affected by head pressure, I went a simple route: I installed a valve after the UV unit and directed the the outflow to a marked 5 gallon bucket and measured the time it took to fill it. After playing around with it a few times I managed to get it very close to the recommended flow.
