I'd recommend 1" manifold to 1/2" on the waterfalls and use like a 2000gph pump.
Kinda sucks you can't just use 2 lines and cross off onto each site. Itd be in your walkways.

Ill probably end up doing 2 1000gph pumps, finding a bunch that are well under 100w each and most of the stuff im finding above 1500gph is over 200w. Will look for probably days/weeks before I buy anything as I dont need it for a while yet.
My 2 air pumps are 112w each so I want to at least go a bit lower if im not going to use them.
yeah 1" pvc then

Have you every used any kind of filter on your water system? Ive seen a lot of veggie hydro gardeners using them but never and weed growers.

Just use a mesh filter bag tied around your pump. It keeps everything nice and clean and easy to clean. You just pull the bag off, dip it in some clean water and put it back on.

Yeah I guess thats a little bit easier, I was just thinking like a sediment filter type thing.

Ya a bag makes it a lot easier. If you use RO water, there's nothing to filter out anyways.

Here's a pump that's 1600gph. 100w. Super cheap and has worked well.

Yeah that makes sense. Cheap and replaceable.
I didnt see that it could have a 1.5" outlet.
I'll pick a couple of those up soon then.

Now I wish I wouldn't have cut these. I only have a few left that are 90 bends. They are 1/2" The little screen pops out and they have what looks to be a 3/4" slip fitting.

agreed.
you should buy 2 anyway. buy cheap and buy a spare. warranty doesn't do jack shit if your plants all die before you get it back. lol

So true. Haha. 1600GPh is more than enough I'm sure. If you can find one with more output that's not ridiculously more expensive, go for it. But from my research, 1600 is about the top, before you start getting in to higher prices and odd shaped pumps.

What would you need 1/2" fitting for? That 1600gph pump I linked you cones with SO MANY fittings. It's a little ridiculous honestly. Haha.

have you estimated roughly how many gallons your system will hold when it's running? that might be a good place to start to figure out your gph needs

He said 120 +/-10
Really most important is just getting pressure at the waterfall sites. You want really more of a water SPRAY with some pressure behind it so it agitates the water well.

this

and I could have used them for my waterfall fittings since they were 90s, I already have the perfect size bit for them. I could have done a 1" line with 3 1x3/4 t fittings and connect that to the back of them.
Was just looking at if I could reuse them. I could potentially put them in the lid and just attach the water bar to the lids instead of the boxes.. but that would take either more fittings or id have to run it along the top so ehh..

No no no just use simple 1/2" barbed elbows. Stick it from the inside of the bucket facing down, and connect a 1/2" black vinyl tube from the manifold to it on the outside

3/4" tee with threaded 1/2" bushings glued on. They sell these little black fittings at sprinkler stores that are just a 1/2" barb with a thread on one end. Works wonders.IMAG0176.jpg IMAG0180.jpg IMAG0182.jpg

Thats what im saying, they were barbed elbows.
I could have done that but without the hose straight to those fittings, or I could have cut the elbows off the bulkheads and at least used that part with hose lol.

I'd be wary of a high output pump. I starve my control bucket with a 1000gph. I have a ball valve on the output side of my pump to throttle it back.

I also have 3 outlets per tote that run back to control 3 separate lines.
