UV with T5s

[oreo54]

Here's data from Jerlov. Penetration of UV through a water column depends upon wavelength and 'type' of water. Jerlov classified seawater into 'oceaninc' (blue) and 'coastal' (green) waters. If your aquarium is well maintained (water changes, GAC, etc.) your water likely resembles Type I Oceanic (the 'clearest'.) Unfortunately, his data includes only UV-A at 375nm buthe found that better than 95% of UV-A @375nmwas transmitted in Oceanic Type I water.

I don't have access to this but might be interesting..

Partitioning of underwater direct and diffuse ultraviolet irradiance in a shallow water coral reef

In optically shallow waters of coral reefs, the contribution of both direct and diffuse ultraviolet irradiance is poorly documented yet its involvement in biological processes is highly significant. Here we present a new approach of partitioning the ultraviolet attenuation coefficient into...

Rehashing this, I suggested to my husband we consider using one of these (others would be ATIs) to the T5 unit. What do you think? Just one bulb for a little UV! And will most of it be absorbed/wasted with acrylic ATI cover?

Depends on material and thickness..

Thanks, what do you think of the spectrum, worth a shot?

Wow it looks like no transmittance of UV below 390 through acrlyic, am I reading that right!?

Unless ATI is using UV acrylic as a splash guard, doubt that right? Perhaps I could replace splash gaurd with glass or UV acrylic
