Working on new tank design and build. Planet aquarium 235 and trigger 48” sump. Clarisea sk5000 roller mat, bubble king skimmer, two vectra L2 pumps. Uv sterilizer and two brs reactors to hang in the sump.

Question is to run build a manifold with ports for reactors, or to just run inline to return and one with the uv to return, and run the rectors off their own small pumps?

What’s y’all’s experience with manifolds?

It's better to have a manifold and not use it than need it and not have it.

My return pump pushes twice what I need and I wound up using a manifold to re direct water to my algae scrubber and I have a port I will use later on for my co2 reactor.
This uses existing pump and cuts down on power requirements otherwise using other pumps

I’d add a manifold. Easier to do now than later. Can come in handy down the line. Doing a build now myself and added a 3 port manifold. 1 port for UV, the other 2 to be named later.

I’m planning to run co2 scrubber off skimmer.
Then one L2 pump to UV then return to tank.
Other L2 pump to manifold then back to return.
Thought in that set up? And if you have any pictures would be greatly appreciated.

Here’s a pic of the manifold before I installed and piped it. I can send a pic of that tomorrow. Not sure I follow your setup. Manifold is really if you’re going to run multiple things off your return pump. If you’re going with individual pumps then manifold prob isn’t needed.

It’s pretty amazing how useful they can be. Add some. You won’t regret it. Recirculating skimmer, UV, reactors, algae scrubber, getting flow via tubing to another part of your sump, it’s only limited by your imagination.

I run a manifold, but I do it using a separate pump from my return. This allows me to utilise spigots as needed without changing the flow through the tank. I run my manifold pump dry, as opposed to in my sump, as my manifold is in my laundry / wet room behind my tank. This keeps the tank cabinet as mess free as possible, while maximising the utility of the manifold. I don't see this a lot (Most people seem to favour hard plumbed manifolds in their tank cabinet) but I've had both and I recommend an external manifold if you can.

For your manifold pump, I also think variable speed pumps are a good investment, as you can increase / decrease flow as you use spigots for different applications. It's also handy to have an additional known good pump to hand in case your return pump fails.

I like this idea. Thinking I may get a smaller DC pump to run the manifold off. Then have the 2 L2 for the returns.

I didn't, and wish I did. I keep adding new pumps for each accessory added. Regret not doing a manifold. I say go for it! Worst case scenario, you don't use it and waste <$80 in plumbing parts
