Need Actinic Suggestions

[Delphinus]

I don't know much about the Aquaconnect bulb. Are you married to the DE idea? Because I recently tried out the Iwasaki 14k bulb (175W mogul) and man let me tell you I wish I hadn't sold my other 175w ballasts because it puts many other bulbs in the 250w size to shame. It's not blue though like what you would expect of a 14k label, to me the colour is "what a good 10k should look like." I guess it goes to show though that don't get hung up on labels because they mean next to nothing. The only problem with the Iwasaki 14k is that it's hard to find and it's not the cheapest bulb out on the market by any stretch.

But anyhow. The issue here is that a 20g is a small footprint to work with.

I did shoehorn some VHO actinics into my 20g canopy, and I had a 150W small floodlight style pendent in there. It can be done but it sure was tight.

If I were to do it all again, I'd probably just go with a good 150W lamp, a decent reflector, and probably not even bother with a canopy.
