For the last 2.5 years I have been using two Arcadia Plant Pro J5 tubes on my Rio 125. They have served me very well. I am impressed that they have maintained their brightness for nearly three years, and plant growth is good. For anyone who is wondering, the Kelvin of the tubes is 5600K, and they are 28W each, just like the Juwel ones.
Now, I know that Arcadia have been having a rough time in the last couple of years, and it looks to me like these plant pro J5 tubes aren't available any more. Anywhere that sells them just lists them as "out of stock". So it looks like I have to look at other options.
I could go back to using the standard Juwel tubes (a combination of day + nature). The day tube is 9000K and the nature tube is is 4100K, so an average of 6550K. So about 1000K more than the Arcadia plant pros.
If I used a day tube and a colour tube (6800K), I would have a higher average K of 7900. Or I could use two colour tubes to have 6800K!
If I have understood correctly, plants don't care about Kelvin. It only makes a difference to us humans, in terms of how the tank/ plants look. So, I'm just wondering what the optimum colour temperature would be for "viewing pleasure"? And what are people's thoughts on the best combination of tubes?
Thanks.
