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..

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
