Sump design

[airvicconcre]

hello all. I'm planning to convert my 6ft 140gallon freshwater discus tank to a FOWLR. I will make a 5FT sump under it. please give me advise and suggestions on sump designs. I want to make a refugium attached. thanks

i dont live in the USA. i live in India and it is difficult or next to imposssible to buy ready made sumps hence asking for advise. i already have a Reef and we made a diy sump for that however we made it way too congested. now i have space so i can do better. this new marine tank will be fish only.
