im also keen to know how a cycle can be done so fast, and the process in which things need to be done. Seems like alot of chemicals and stuff to be putting into a tank 2-4 hours before the fish... But, im not going to say its impossible, as it obviously works for you....
Nice tank BTW. I dont like goldfish, and i prefer my tanks differently, but it doesnt matter, you like it, and it does look quite nice. Everyone has their own tastes eh?
Well done, and good on you for saving the poor goldies
