What Would Be The Best Breeding Set Up?

[1Filmproducer]

Hi,

I plan to breed discus as im sure 90% of you know already. Im only doing it for a bit of fun and to sell to local pet shops if they breed. Im currently looking at the aquariums. My plan was to buy these things, firstly the stand ( 2 tier)

Then i plan to buy 2 of these to put on it.

They currently have 3 sections in them and i was planning on removing them. But then someone said have a cube tank. But now im confused, this is the cheapest way i can find and it works for me as 4ft is the size ive got in the garage. But should i remove the sections so i have 2 4ft aquariums to breed discus fish in or should i remove them in one or none of them. Considering 1 sections / tank has to be for the parents. And then a rather large section for growing out fry. To 6" odd, then i would like if theres space, a section to keep 2 discus to grow for showing, im planning to attempt it in Merseyside aha

Any way, could anyone help, give me some advice,
Thanks
Mike
