75 Gallon Tank Flow

[WatchBrowns]

I am thinking about grabbing a second Aqua Illumination Orbit 2’s to place on both ends of my 75 gallon tank (48x18x21) and running them at about 30-70% on a random cycle.

My tank currently houses (2) clownfish and I will eventually add an anemone, soft and LPS coral, and a handful of additional fish/inverts.

Will (2) AI Orbit 2s alone be sufficient for flow in this tank or should I need to introduce a few smaller power heads/wave makers as well?

I have (2) current USA loop wavemakers and an old Hydor Koralia Evo on hand if needed.

My sump return pump is likely only running at about 300gph and I am also running a Fluval FX4 canister filter at roughly 425gph and is primarily acting as a media reactor, helping increase water flow, and assisting with quick/easy water changes.

With a second Orbit 2 (both running at 75%) and without the wavemakers/power heads, I would be sitting at just under 4000gph of flow with the option to ramp up to just under 5000gph.

Should I include the other wavemakers/power heads or would my flow already sufficient with the 2 orbits, sump pump, and Canister Filter?

I would start with your idea for the 2 orbits and then add as needed. Your corals/tank will tell you where flow is too much or not enough.

What frequency and pulse should I be on for a 75 gallon tank with 2 clowns and an anemone
