Dry fitting could be the answer you are looking for.

Hello!
After a 10 year break I’m finally back in the hobby again!
What sizeing of the pvc tubing would you guys recommend me? I’m planning on running a 23 g DT and a 20 g sump. I have an Aquabee Up 2000 that delivers 500 gph and I’m planning to use this as the return pump. The nozzle of the return pump is 16 mm inner and 22 mm outer fittings.
Really looking forward to get started in this awesome hobby again!

With a max of under 40 gallons I would follow the pump output size with hose.
Getting ready to set up my 220 with a Beanimal overflow. The Weir box will run the entire length of the tank. I have read through and keyword searched through a lot of this thread but still have some questions. Thanks in advance for the help.
1. I plan to drill the center of my 1" bullheads at 3.5" below the top of the glass. How far down should the notches in my weir box be cut? Down to 2.5" from the top of the glass?
Another way to ask is how far apart should the center of my bulkheads and the bottom of the weird notches be?
2. Where is in the world would I find a 1" slip x 1-1/4" street 90? Can I just use a 1" street 90?
3. Should the bulkheads be slip x slip? Thread x Thread? Mix? If mix, which side thread/slip? If slip, should I use Oatey transition cement? If thread, should I use teflon?

Bulkheads. The side that faces inside the tank do not have to have a tight seal. The gasket against the glass takes care of that. For ease of removal slip is usually used. For the outside you need a tight seal, so you do not have a water leak. Threaded is what I use. I use Teflon tape. It works for me. I just dont like the Teflon paste.

Weir teeth. The depth of the teeth will dictate the height of the water in your tank. The amount of teeth and the spacing plus your return pump size will dictate the amount of resistance that will buildup against the teeth also effecting the water height in your tank. This will also effect the drain back into your sump when the return pump is off.
What height of head pressure on the pump and what size pipes are you using for the overflow?

Better to oversize the pump and need to throttle it back, than to buy a smaller pump and need more flow....

Seems likely that you are not returning enough water to fill the 1" drain below the valve. A 1" fill siphon can handle about 960 gph.
I could not find a head loss chart for your pump but it seems like it would pump about 250gph at 5'. If that's the case, 1" seems like it would be too big.

For the money, if you are going with a Jebao, I would just go with a 12000. It's not much more, but it gives you a ton of variability

Yes I’m thinking that is the problem as well. If I would have a stronger pump and maybe the valve half open would it still pull around 960 gph or is it less? I’m thinking about which pump to buy.
If you have the valve half open on a 1" pipe, it will pull less than 960gph. How much less? I don't know.
I like my sumps lower flow so detritus settles. I run about 2x total volume through my sump. My sump is 100g so about 7x sump volume. I have a 400 gallon system and my return is about 750gph.
If I had your system, I would only want about 200gph max on my return and use 1/2" for the drains.
If you are pushing 900gph on your return, that's 30x total volume through your sump. If you have a 10g sump, then you are running 90x of its volume. That's a fast sump.

To me it seems straight forward. In lieu of filter socks the rollermat would take its place. it might require some ingenuity but I don't see a reason why not.
What concerns do you have?

If you're familiar with the placement of the return pipes (other than the emergency), you will notice that they are submerged. That affects back pressure and noise cancellation.
So, how would you use the rollermat when the water feeds it from above?
