Looking great, excited to follow along! You know, as I plan my next tank I have been lulled into the assumption that it has to be rimless. But when I think about the rimless 20g tank I currently have, it always has a black cover on it (looks like a rim) and I would love to go T5 lighting in a hanging canopy, which basically reduces the visual impact of a rimless tank, too.
So now I'm asking myself, if I can get a 40g breeder AND a steel stand from Petco for less than $100, why would I spend over $1,000 on a rimless setup that won't look rimless by the time I'm done with it anyway?
Plus...I like clear silicone better than black...there, I said it. I know, it's heresy, but I do.
You've given me great things to think about. Imagine what I can do with that $900 lights, skimmer, return pump, controller-wise!!!
