Can somebody help me with my plumbing???

[Tom Giddens]

I bought a used tank with overflow and none of the pieces are in the overflow. This is my 1st time having a tank with overflow I am excited and nervous at the same time. (Afraid I will end up with water all over my living room)I bought this for the return https://vividcreativeaquatics.com/s...ate-xxl-return-line-upgrade-25mm-to-34in-rfg/
and now I don't know what to get o complete the rest of the drain and return. I spoke with Antonio the owner at Vivid Creative Aquatics and he said there would be plenty of people here that have been in the same spot and would help.

Looks like you have the return part handled, minus the part from the pump to the return nozzles. For the drain, we'll need to know what type of overflow you have.

The overflow box is 5" on the sides and 8" across the front It has grooves cut on 3 sides 3/8 x 1-1/4 here is a pic The bottom of the tank has 2 holes 1 I assume is for the return it is 1-3/8 " and the other is 2-3/8 "
