I know it seems like the tanked crue does everything in one day and adds straight hose water and such... But if you watch the shark episode, they even mentioned they had to leave the tank and come back later. I bet they dumped some ammonia in before they left. Theyve mentioned it last season too. I think they try to make it look like its all done in a matter of hours, but fome on... They have such a huge successful business, they wouldnt have gotten this far if they didnt know what they were doing. And when they are running a hose through the house, its probably some pre mixed saltwater being pumped from their delivery truck, and if it is just regular water, they dont do corals... So its really not as important. Ive seen where they actually did a complete reef set up and they had a sump and refugium and every thing.
Its a show made for tv... Come on, they get less than an hour to present their aquariums, theres a TON of info that has to be left out. People also want instant gradification. They want to see them just throw a tank together and say tah-dahhhh! They dress in the same clothes to make it look like it happened the same day because thats what people want to see. Notice how its ALWAYS day time? Can you immagine setting up an entire tank that big in a matter of hours? No way, that tanks all day. Im just saying... They make it look that way on tv because thats what people want to see. In reality, they dont have a week to build a tank, can you immagine how big the waiting list must be for that place? They know about it wayyy in advance
