Flow for a weird tank size

[BristleWormHater]

I have a IM 25 lagoon (dimensions L=25in W=23in H=11in) I am really struggling to figure out how to set up its flow. I plan on keeping lps corals like, blastos, duncans, torches, hammers, gsp, and waving hand anthelia. I also would like to keep a crocea clam and feather dusters. Right now my flow nozzles have a blind spot right next to the overflow chambers where the filtration is(video below). I am considering getting the IM spin stream nozzle would that help? Also wondering if I need a power head or not.

The return pumps I’m using are the stock return pumps from IM here’s a pic

Definitely need a powerhead.

What powerhead would you recommend?

These pumps are also adjustable what should I set them too? Or should I just get better pumps?

do you have documentation on your return pump that states the flow rate? Usually expressed in gallons/liters per hour. As for a powerhead, something along the size of a Nero 3 would be sufficient.

The return pumps are 130gph at maximum

Nero 3 is 2000gph and $200 I’m looking for something lower end and cheaper any more suggestions? Thanks!

Use multiple small pumps like Jebao ELW 5 and 10. I had 4 of them in there at some point.

Would 1 ew5 suffice for my tank?

So doing some rough math:

Assuming you have roughly 22 gallons of water, each pump will turn over your tank volume 6 times at max flow. I assume you have two?

I would set to about 60% and see how things look.

As for cheaper power heads: a lot of folks use some that are sold on Amazon, such as This one

Yes I have two and I have them set to here hard to tell how much it’s flowing because it’s just a manual dial

You will have to play with it. It should be fine at least in the beginning. You will end up with some deadspots with just one powerhead.

So 2 then?

 

[paragrouper]

You can visually see the opening. Set it to half, then increase a bit. After you get it running, watch the tank. If you still have dead spots, increase the opening and follow up with power heads

There's another option you might consider. You can run two 1/2in Random Flow Generator nozzles and upgrade the return pump.

You can start off with your current pumps, but you may find you get better results with something a little stronger. two pumps at 200-250- GPH each or a single pump in the 400 tp 500 GPH range.


Essently, If you can increase the flow output to something in the 450 to 500+ GPH range then you should be able to do this tank with LPS and softies without any power heads.

For instance, if you ran a single IM Mightlyjet 538, and

two 1/2in RFG will easily flow that entire tank.

You would need two 1/2in RFGs, and two 19mm Slip-For-Drop adapters.

You'll find both of these options at all the major online retailers and possible you local fish store. You'll also find them on our own website here:

If you can increase the pump to something in the 450 to 500+ GPH range then you may actually be able to do this tank with LPS and softies without any power heads. You could use the IM Mightlyjet 538, or any other DC pump that can fit in the back chamber

Run two 1/2in RFG with a god size pump will easily flow that entire tank. You would need to 1//2in RFGs, and two 19mm Slip-For-Drop adapters.

I think I have one of these laying around somewhere. @BristleWormHater , you are more than welcome to have it if I can find it. Also, if your looking for a more affordable powerhead that is tunable, the jebao pumps like This are fantastic

Ok I will gladly take or pay for it pm me if you find it and I’ll give you shipping address.

Nice! That's super cool of you

Do you have the 19mm slip-fit-drop adapter as well? For that tank, the adpaper is required for the 1/2i RFG to get it below the water line

Thanks everyone I’m putting together a shopping list now. 2 adapters 1 or 2 random flow generator(s) (ty @19Mateo83 for the other one if you find it) and 1 Jebao mow
