piping

Do I need schedule 80 for everything or can I use 80 for valves and other stuff and than just 40 pipes

Yes, box stores only carry white, if you want colored, probably have to order it

i dont really care for colors, but ive heard 80 are higher quality for the valves

true, they are

Can’t really help with imperial measurements because I’m only familiar with metric, however - pipe sizing depends on the expected turnover and drain configuration (i.e: one drain + emergency would be bigger than 2 drains + emergency).

Usually when going with the classic return + drain + emergency than the drain will be larger than the other two.

I think schedule 80- just means the pipe outerrim thickness

Schedule 80 and 40 are interchangeable OD is the same

Interesting, apparently I did know the word for it in my language, though I always thought it’d be the diameter of the pipe rather than the thickness.

Interestingly enough, to my knowledge the only use of imperial measurements here are for agriculture piping.

Metric is so much simpler, just put I.D/O.D with no fractions or whatsoever and be done with it

We tried the metric thing in the US for about a year when I was in the second grade back in the early 70's, ya no. I'll stick with Feet and inches

You mean Metric?

Ya, corrected LOL

So I could just get the cheap pipes from home depot and than use higher quality valves , unions etc?

Yes. Schedule tells you how much pressure a pipe can withstand. In an aquarium, this is almost nothing vs what the pipe industry puts their stuff through. I like Schedule 80 for bulkheads because they are stronger built but they require a bigger hole to match. Otherwise, I use 40 for everything else. The only valves I have on my system are a gate valve which is Sch40, and two 3/4” barb valves for my vinyl return lines. I would never use a Sch40 hardware store ball valve, they are just too hard to adjust.
