Flow ideas for a 90g

[Reef_puck]

What would you use for flow in a 90 G reef? 48x18x24.

not including the mile sump return.

Tank has algae issues right now as well if that makes a difference.

I ran two 2k gyres on my 80g display tank, one at either end, running around 50%.

What are you currently using for flow in the tank?
For a four foot tank, you have plenty of options. From a MP-10 on each end, or Jebao, Nero, Tunze, gyre... What corals, if any, are you planning on keeping. Flow really depends on your aquascape and corals. SPS dominate will need higher flow, LPS/softies less flow.

The algae is another issue. What are you parameters at the moment?

Excellent choice!

A pair of gyres!

 

[Reef_puck]

Had a MP40 that just broke. And a reef breeders RP-25 along the back.

I'm leaning that way as well for a 75g tank. It's only 18 wide, those gyres would do great!

With the Gyres do they really get clogged fast is the tank has algae issues, and are you referring to the Maxspect Gyres?

So you are running with just the RP-25 and your return pump?
Do you have many corals?
What are your parameters to try and address the algae issue?

If your concerned about the algae, lets get that figured out too. But, to answer your question. Just like any other powerhead, maintenance is key to longevity.

Mine are icecap 2ks, but presumably made my maxspec.

1.5 years in, never cleaned, not clogged. Your mileage may vary of course

I had another thread working on the algae and corals. The MP40 just broke this week.

So running just Gyre pumps against each other along the top of the tank gets enough flow to the bottom and throughout the rocks?

Yep.

I do mine a bit different because I like the sides clean.

This is a larger tank, 6 footer, and the gyres are on the back glass on either side of the overflow. I point the flow in to the back glass around 30 degrees and it circulates around the sides and to the front and meets in the middle.

Yes, mine got clogged even without algae issues. Nothing moves water like a gyre but it was too much tinkering for me. For a cheap option I bought a Carefree Fish wave maker that is dead silent and worked well for a year and a half. It still works well but the controller got fried so now it is frozen on the settings that I had it on. The bigger model is under $90 on Amazon. It's about the size of an mp 10 so low profile. Of course it does have a wire in the tank.

Vortech's are great but pricey. In my 75g which is the same dimensions as yours I have an mp 10 and mp 40 on the right side and the Carefree fish on the left and its plenty of flow for my mixed reef.

 

[Reef_puck]

So you run the gyres verticals and not horizontal. With the offset overflow not sure where I would place these. Where it would not blast corals . Maybe need to remove rock as well.

 

[Reef_puck]

If the gyres would work o will look into them.

Will The 2x2350 gph will be enough for anything in the tank?

More than enough IMO, and good too because running pumps over 70% or so, IME, gets them to start to be noisy.
