SCA 66g plumbing help.

[reefgall]

I have no clue how to plumb an aquarium this is my first time, I bought this tank used and it comes with nothing but the sump and tank so I have no plumbing tools.. I know this is a long shot but, Can someone please tell me every single part I need to plumb this aquarium? or what parts you used?? I asked SCA to send me a kit and they haven't gotten back to me.. the tank has 3, holes drilled to the bottom and it takes a 1" bulkhead (that's all the info I have/ could find). I've done a lot of research and can't rlly find anyone who says what size tubes they used for everything. I know how to put everything together and I know how it functions I just do not know what sizes to order for every single part to plumb it. Ive watched videos on how to assemble but nothing describes sizing. all I know is it takes 1" bulk heads and has 3 bottom drilled holes. I know this is asking a lot but I thought it wouldn't hurt to try so... IM open to plumbing it the most simple and easy way, so please suggest the best style to plumb. Photos I found of the system :

What exactly are your plans? You can go with flexible tubing, all PVC, or combination of both, kit for overflow, etc. The easiest would be to look for a 1” overflow kit on amazon and use flexible tubing in the sump.

So you have 2 drain holes, one set slightly higher as the emergency back up drain, and one hole for returns that will be split into 2 lines above.
I like my return lines to be flex, and I like braided line.
Durso would be the setup on this.

There is some info on my build how I did mine, but I don't know exact sizes for yours, maybe hop on SCA FB page, lots of people should be able to assist you there.

Mine is older and drilled slightly different, but some of what I did may help you.
