If I want to use the preset OGC mode should I keep the factory installed rotors A and B on or do I need to change the rotors to A and A or B and B? I have 2 xf250 pumps on opposite sides of the tank.

Really up to you. The OGC is really dedicated to running in alternating gyre formation which is either an A-A or a B-B cage and propeller. But with stock A-B you get an unusually flow pattern and may be a more attractive option if you have your pumps mounted horizontally.

Hi Jeremy and Coralvue team,

Can you clarify on this... if using dual xf250, is the correct OGC mode to use either both pumps as A-A cage and propeller, both pumps as B-B cage and propeller, or one pump AA c+p and opposite pump BB c+p?

Is this the same for Lunar LTC?

You can use AA or BB. It all depends on how you mount the pump, what orientation and where it points to. In terms of the LTC, you should leave it as default (A&B).

If they are on opposite ends, the left one should be AA, and the right one should also be AA? Or should they be opposite, the left one should be AA, the right one should be BB?

Not necessarily. It depends on what flow you want. You need to ask yourself... If you are running it vertically, do you want the top of the pump to push water to the left and the bottom push water to the right or the other way around. That will dictate if you use AA or BB. If the pump is running horizontally, do you want the left side to push water forward and the right side to push water in reverse or the other way around. That will dictate if you use AA or BB. It is a matter of how you use the pump.

Thanks Carlos :) I really like your videos. Perhaps you can ask Maxspect to make more demo videos of each mode. The Intro video they put doesn't have LTC and OGC modes, and each mode they demo is very short.

I will pass on the information and request to the manufacturer.
