Cool? As in cool looking aptasia?
I've been in there once or twice, not too impressive IMO; especially the price tags.
But if you're a regular at Big Als, you probably won't notice it though LOL. Go to King Ed or J&L, price for livestock and equipment are much cheaper. $5.99/lb for LR is a decent price though. But I'd still get it through J&L, a little cheaper (depending on quantity) and the guys there know what they're doing.
