Beautiful build , I am following as well . How is the quality of a Crystal Dynamic Aquarium , I have received a couple of quotes for them on a custom tank as well a 29x24x24in about 73g and I was wondering about the quality of them? But I was also thinking of sending them a quote for a 120g as well... can't decide on my next up grade going in between a couple of tanks ... and recommendations? Either a 60g cube , customs 73g by CDA , or a 120g ? Possibly custom as well ...
