+1 , With our wind storms and the trees around here, I don't think I would be in this hobby if I didn't have one, with all those little Benjamin Franklins swimming around in the tank.:)
I got a chance to stop by there today for a few minutes, I think it will be on my fav list, like finn said lots of tank space and very clean, I will probably go back for a rbta and a yellow tang due to pretty good looking livestock and the prices.
I have replaced several inches of sand in all of my tanks with no ill effects to any livestock, I used a funel with a tube on it, its kinda in the same lines of a beer bong,lol
but it works great! make sure to rinse the sand well before though.
