It's true that there is a fantastic amount of information here (and we're very grateful for the effort you've put into it!). I'm not trying to be lazy; I've read through this thread several times and have two main questions that I haven't been able to find the answers to:
1) In the quoted thread above, you recommended a Deep Blue light that isn't otherwise mentioned and I was trying to clarify which model you were referring to. The one I linked is in the price range you mentioned, but only seems seems to be a single 3W white LED with a tiny blue LED on either side. Were you thinking of a different model?
2) There has been some "x vs y" in your comments over time, but I was hoping to get more of a read on the sum-total of your thoughts (especially for the larger 25cm cube, since most of this has focused on the 20cm ones). The AquaTop Nano-P is obviously too strong for low tech, so what would you get if you didn't have a spare light sitting around? All of these are in the $30-40 price range:
-The untested Solarflare?
-The unspeced potential successor to the Up Aqua that has been discontinued?
-The Finnex Finnex FugeRAY-R
, which seems to be a decent product despite the poor electronics placement? (mine is well-sealed, BTW)
-Or would the Wavepoint still be your go-to for this sort of tank?
I'm leaning towards the Wavepoint or getting another of the Finnex. The Finnex really is a nice color with the red LEDs, but I'm not sure if its 5W would be too strong for a 25cm tank (and I'm terrible at eye-balling this sort of thing, so I wouldn't be able to look at it and tell without depriving one tank of light for an extended period to test my current Finnex on the cube). Conversely, I'm concerned the 3W of the Wavepoint would be too weak for the larger cube. I have very little experience with this size tank, so I'm not sure how to choose between these two without the luxury of being able to try both.
